  1. Apps for the Fossil Hunter

    I've been wondering if anyone on the forum has a favorite App or Apps they've found useful in searching for fossils? I haven't been able to locate any apps that focus on mapping your location in relation to underlying bedrock data, and it got me curious. Thanks! Have a good weekend!
  2. So today Ive went down to the bay that I was planning to find fossils in for awhile, only to come back empty handed (I couldnt reach any of the shale quarries and just decided that its layers are too flat to house fossils anyways). Being a Palos Verdean, There are small pockets of quarries which are generaly unprotected by preserves (usually alongside roads, sometimes beaches). Palos Verdes has a rich history of Miocene-Quarternary fossils, but much of the fossiliferous zones are protected by preserves. Because I cant really go far just to find fossils, I can only hunt in the small pockets I can find. Ive studied some geological maps and do know where the according-to-theory fossiliferous shale are, I just dont know how exactly to find fossils without destroying the place and getting under a legal flat. Are there any tips and tricks for this kind of fossiling?
  3. NC & VA Rivers

    Can anyone explain why the majority of rivers in NE NC and SE VA have most of their high banks/ bluffs on the southern (right) sides? And please let me know if I have that wrong and they're not skewed that way.....but it does seem like that. Thanks.
  4. Hey all, I've recently caught the "fossil bug", and I have been looking at geologic maps online to help determine potential hunting locations. Is anyone aware of an exhaustive website, book, etc. that labels stratigraphy? If not, what do y'all use to determine the age of certain locations/formations? Any advice is appreciated! Thanks, Caleb
  5. Dear TTF Members, I was wondering if you experts on the forum could provide a more in depth explanation of time periods such as the Mesozoic Era and what kinds of creatures dwelled at these times. I would like to learn more about the evolutionary timeline to help me become a better fossil enthusiast and helper in this forums' community. Sincerely,
  6. For anyone who finds themselves up to the challenge of fossil hunting in Massachusetts/New England I have a couple of very informative books to recommend. These books are also relevant for anyone hunting in Connecticut and Rhode Island. Fossils can be hard to find here in Northeastern USA so it pays off to do your homework! I've met both of the authors of these books and they're definitely experts on the local geology/paleontology. Happy Trails! Title: Carboniferous Plant Fossils of North Attleboro, Massachusetts Author: Steve Emma Description: An in depth guide to the Pennsylvanian aged plant fossils that can be found in the Narragansett Bay area. This area includes southern Massachusetts and much of Rhode Island. Title: Windows into the Jurassic World Author: Nicholas G. McDonald Description: An in depth look at the Jurassic aged geology and fossils found in the Connecticut River Valley area which extends from Western Massachusetts down through Connecticut.
  7. If you could spare a few minutes then please read the description for the wonderfully apt title for the book below. " Chrissie and the fossil tree " https://depositsmag.com/2017/03/28/chrissie-and-the-fossil-tree/
  8. Career in paleontology.

    *Looking for some advice from paleologists and/or geologists* I am thinking about going back to school. I dropped out of college 10 years ago because I was never quite sure what I wanted to do. I have taken a lot of course hours, but I do not have a degree since I basically took anything that interested me. Now that I am 30 and a bit more stable, I would love to go back. I am extremely interested in paleontology, but I know that it requires a lot of school, and it isn't easy. From the small amount of research I did, it seems like most paleontologists do their undergraduate degree in either biology/geology. I would love to hear advice from anyone who has either done or looked into doing this. I live in Florida, so I am thinking UF might be the best choice, but I am also wanting to look into doing as many online courses as possible. Thanks in advance!
  9. Deposits Magazine

    Deposits Magazine is quite a popular read here in the UK. And I can thoroughly recommend it to all aspiring fossil and mineral collectors. The Magazine on Fossils, Geology & Minerals. Deposits is both a printed and online magazine featuring articles by high profile authors. I hope to help on a article in the magazine some time in 2017. As I continue on my self educated journey. Utilising my free lessons of advice here on TFF. https://depositsmag.com/

  12. Geological mapping question

    I am having trouble figuring out a geology mapping problem. The problem is "Slickensides Oligoshain Formation pitch 60 degrees N on a fault oriented at 335 degrees, 60 W. What is the plunge of the slickensides". I kept getting arctan of 1.5 as my answer, but the answer key disagrees. Any help would be appreciated.
  13. Stumbled on this today. Dated 1936 but has some great info in it about time periods and shore lines with relative elevations. PDF format. https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=4&ved=0ahUKEwi92tatsvXMAhVKaT4KHanOAHMQFgg1MAM&url=https%3A%2F%2Fpubs.usgs.gov%2Fbul%2F0867%2Freport.pdf&usg=AFQjCNHJWSf2eOZOiDbN9Ow2rqkMe5vxaQ&sig2=mfMXvhHbqU1RQtOcJaoPjw&cad=rja
  14. Does anyone know where I can get my hands on a decent stratigraphic wall map of North America? Or a stratigraphic atlas of the United States? I've seen very pretty ones, but I can't find one that is commercially available. Thanks in advance!
  15. Over Christmas, my husband and I visited and photographed the Orton Geological Museum in Columbus, OH. It's a small, single-room museum in the geology building of Ohio State University. It's well worth visiting! My photoset is a compilation of four different photo sessions, one from my first visit in 2010, the other three on different visits during this trip. If you want to know which visit a given photo is from, look at the image title: my format is a picture number, a photoset letter, and an image description. The 'a' set are from 2010, the rest from 2015. Where I had multiple images, I chose the best one to post here. I'll start with some views of the geology building, Orton Hall. It was purpose-built in the early 1890s to house the geology collections and library, out of Ohio stone and clay. The tower houses a set of bells to ring the hours, and is ornamented with a lot of gargoyles: More building pictures next. Unfortunately, my photos are too large to include more than a few of them in a single post, and my image compression software doesn't have an option for another 50% reduction.
  16. Almost there! Over 270 pages of full color fossils from the Pennsylvanian of North Texas The long-awaited sequel to the Pennsylvanian Fossils of North Texas (2003) Available Q4 2015 in hardcopy, digital and e-reader formats.
  17. I still carry my trusty Geologic Map of New Mexico, tucked inside my gazatteer, right next to the BLM use maps. But this... ...mapView:Geologic Maps of the Nation... ...has been a wonderful prospecting tool. You can overlay geology onto road, topo and satellite imagery! Fossils, look out!...explorers are on the way. Happy Hunting! -P.
  18. This was totally spontaneous and done as we moved through the project. My only suggestion if anyone else wants to do it is get your ingredients for a legit cake or brownie recipe first and use the flour for your initial glacier project... the texture of our "creation" was not very cake-like, but it was good nonetheless. http://fossilforay.blogspot.com/2015/06/a-fun-and-yummy-way-to-show-kids-geology.html
  19. While looking for some of our crystaline finds from a trip to Rose Creek Mine (Franklin, NC) my 12 yr old, Duncan, found he had what I believe is fossilized coral. I've searched the web and it seems to be a correct guess - any corrections greatly appreciated! Struggling with a migraine but the best I can seem to find is that Rose Creek Mine is in the Blue Ridge Belt. NC Geological Survey Map has it labeled as Biotite Gneiss with pegmatites interspersed. The pegmatities are shown to be from the Devonian to Silurian periods 390-435 mya.The biotite gneiss are shown to be within the Ashe Metamorphic Suite and the Tallulah Falls Formation. This is a decent map of the area around the GA/SC/NC/TN mountains showing the geologic formations. So what I've learning while searching for information on this fossil is that the area was once part of the sea between Laurentia and Gondwana (info). When Laurentia and Gondwana began to collide to form Pangea, that is when the Appalachian Mountains were born. Learned tons looking up this one fossil! Love it! About to school the kids on it now. Again, if I've made any errors in my research, please let me know. Thanks!
  20. Hey there! I know I know, I've been missing in action for the past few months. Work and Field work kept me busy. But I've now am taking the time to update my blog, and sharing some of my recent adventures. This one is not so much of a fossil hunting trip, but of discovery on fossil history in New Brunswick. A few weekends ago I went for a day trip to Saint John to meet up with my friend Matt at the New Brunswick Museum's Steinhammer Lab. He's currently doing a stint at the research facility and I couldn't resist, desperately wanting to tour this historic place. This building was the original New Brunswick Museum until it needed more space to accommodate a growing collection. In the 1990s, the exhibition displays found a new home downtown (Market Street area), but most of its collection (closed to the public) was kept at the original building on Douglas Avenue. This museum is considered Canada's oldest, housing collections dating back to its first proprietor, Abraham Gesner. The influence of the Steinhammer Club, comprised of geologists from the area and abroad, was pivotal in the history of Geology across the globe. They founded the Natural History Society of New Brunswick, and from there the contributions to science have been crucial to the advancement of several fields. I had also wanted to meet up again with Dr. Randall Miller, curator of the collections and museum, but he was currently out of town. I arrived at the old museum in one piece after dodging a hellish traffic and weird road designs. Beautiful city, crappy roads. Matt making sure Steve is hard at work I got to the museum and after talking to the wonderful staff, I met up with Matt and one other friend, Steve. Steve is an amazing fella and will keep you on your toes. They were in the middle of taking specimens collected in recent field work (a couple that I've participated in) and offered to lend a hand. We unloaded the material to the lab, and headed out for a bite to eat. After parting ways with Steve as he headed back to Fredericton, we proceeded in taking a tour of the Steinhammer Palaeontology Lab. I didn't take any pictures as Randy wasn't around and didn't want to take any just in case he didn't approve. Going through the collection, I've seen some incredible representations of various paleobiological and paleobotanical specimens, including many type specimens. Trilobites, which a cast of one of the biggest I've ever seen barely fit in the collection cabinet. Eurypterids, or sea scorpions, that could give you nightmares, were the size of your average family dog. Fish, bones, and even the remains of a wooly mammoth (Mastodon) graced the collection. This animal was collected from the Hillsborough area, near where I live. The tusks were incredible to behold. Walking through the halls, it was easy to get lost amidst the many artifacts laying around, beckoning, hungry for your attention. Even going to the washrooms you have to pass a wall of jars, each filled with animals living, and extinct. One doesn't linger too long in the bathroom let me tell ya. Also among the specimens at the lab were the many trackways that we collected, waiting to be analyzed and studied. Seeing specimens that you helped bring up in the light of day and residing in this place was quite a special feeling. As the day winded down, me and Matt chatted about the importance of keeping collections together, and the crucial role that these play. Every effort must be made to help save these as they help us understand our past and help dictate a future most rich. Our friend Margaret arrived near the end of my stay. As we said our goodbyes, I felt that it was imperative that I participate in the discovery and safekeeping of fossils, and to contribute in the advancement in the fields surrounding those of paleontology and biology. That is why I love geology, as it makes me have an intimate rapport with science, to which I love and am passionate to no end. To understand and comprehend, wonder even for what nature has left in our path, often hidden, for us to uncover and rediscover. Cheers! - Keenan Saint John River, view from behind the museum
  21. a book review of: "The Monkey's Bridge: Mysteries of Evolution in Central America" by David Rains Wallace. Trinity University Press trade paperback edition (originally published by Sierra Club Books, 1997). 277 pages. Suggested Retail: $18.95 USD. The formation of the Isthmus of Panama, the land bridge connecting the Americas, was the most recent, significant tectonic event of the Cenozoic Era. It occurred just over three million years ago and carried with it not only local but also global consequences. The land connection allowed terrestrial plants and animals to invade new territories north and south as it also cut off a seaway between the Pacific and Atlantic Oceans. It would later pose a confounding and deadly obstacle course to Old World explorers and fortune-hunters - a land untamed even into the 20th century. "The Monkey's Bridge" tells three stories: how the Isthmus of Panama evolved in geologic time; how Europeans discovered Central America across the past five hundred years and how the author arrived at his understanding of it across his adult life. David Rains Wallace is an award-winning natural history writer. He has also collaborated with the National Park Service publishing handbooks about Yellowstone and Mammoth Cave. His research leading to the "The Monkey's Bridge" involved extensive travel through the Americas which also produced his earlier book about Costa Rica's national parks (Wallace, 1992). Following a 10-page prologue, the book is composed of two parts: Exploration and Evolution. Part 1 introduces the European explorers and naturalists who encountered the landforms, organisms, and native peoples of Central America. Part 2 focuses on the landforms, organisms, and peoples themselves. While the first part could be said to be the history section with the second, the prehistory section, the paleontology of the region is also discussed in the first and historic figures reappear in the second. Across both parts Wallace recalls his own trips taken from 1971 to 1994, traveling by hitchhiking, by bus, and often on foot. Wallace writes in a very literate but also readable style different from the comparatively flat descriptions of people, places, and things in the average paleo-related story. It's the difference between a professional travel writer and a scientist who is also a writer. He looks for more connections between history, art, and science while a scientist writing the same book might translate the technical into the popular without unpacking as many adjectives. While this book is clearly well-researched as Wallace cites several publications and quotes numerous people, the reader might sense that he is not a scientist from a few minor fumbles. He refers to the Florida Museum of Natural History twice as the Florida State Museum (p. 70, 71). He thinks that extinct horses did not have toes - just hooves (which he calls "hoofs"). In reality they did have hooves on their toes. Related to that, he notes that "three-toed horses were replaced by larger two-toed horses." Actually, three-toed horses had one-toed descendants without a two-toed transition. Wallace does reveal a good knowledge of today's plants and animals of the Americas. He recognizes species he didn't expect to see in Central America - forms seemingly more at home in parts of the United States. They add more diversity to the picture of the intercontinental exchange of organisms after the formation of the isthmus. Other than a map at the beginning of each of the two parts of the text, there are no illustrations. The writing will hold the attention of the average natural history fan and perhaps even interest the more casual reader used to more visual support. However, I think when dealing with extinct organisms and colorful living ones, an author should include some photos and figures to break up the text. Wallace did not feature much illustration in his "Beasts of Eden" (2004) a book about two museum murals, but he did in his "Neptune's Ark (2007), which discusses several extinct animals of the west coast of North America. Even with so little illustration I highly recommend "The Monkey's Bridge" to anyone interested in natural history. It is very informative with an excellent mainstream explanation of the geologic processes that created the Isthmus of Panama. Throughout the book, the reader travels along and experiences the author's first-timer surprise in different areas of the land bridge: the limited stretches of jungle, the sudden expanses of near-desert, and the abrupt changes in elevation. Wallace meets interesting people, visits remote museums, and seems to find himself on the edge of a bad situation more than a few times so it is an adventure well worth reading. Jess
  22. Hi everyone, Here is a PDF called Guidelines for the Curation of Geological Materials it’s freely available from the Geological Curators Group website and is really a must read. Theres also a Geological Curator PDF publications archive on the website. Regards, Darren.
  23. Professional Geology and Paleontology Language Codes.... There are TWO languages in the Sciences: (1) Professional Language (2) Amateur Language There are TWO major sources of Geological Information: (as far as this Topic is concerned) (1) Professional Journals and Books written by Specialists (books, papers, monographs, etc.) (2) Amateur books written in the layman's language (hobby, fossil books for the public) Often, and I probably should emphasize, OFTEN, the amateur collector of fossils or minerals will read a technical paper and not understand some or much of the terminology. There is no disgrace not understanding the terminology being used... but there is also NO EXCUSE not to deCODE the terminology to comprehend what has just been said. I was reading a bit on Cambrian trilobites and it was to prepare for some exploring some Cambrian trilobite locations. It applied to "blind trilobites" known as Agnostid Trilobites. Terms like oceanic-neritic boundaries, pelagic life, lithotypes, laminated strata, mimicry and other Scientific Code Words are used frequently. I am using "Code Words" for a lack of a more interesting term. Scientists can take one word that has a definite meaning. It would take several paragraphs or even a book to define the term... but they know what it means and use these "words". To an amateur, as myself, I must have a way to deCode the language. I have a book in mind that should be on every amateur's desk top, like a dictionary. Once YOU understand the definition of the terminology your understanding will benefit you for the rest of your life. Since most of the terminology has been in use for many years, the Second or Third Edition will provide enough information that is accurate. I see a Fourth Edition is available, but I would not spend the money for a copy, unless you are a Professional needing to use current terminology. A paper written in the past is what you most likely will be using and the terms will be defined in this book. Inliers or Outliers... very important stratigraphy terms in the UK that until I read the meanings... they meant very little to me at the time. Just simple things bring in large consequences. If you have already rolled your eyes back into their sockets... I understand. Many hobbyists have no use for a book to deCode Scientific language as they are not interested in getting into depth of the subject. There are 20% who are curious and want to understand. They are the most active on a Forum in identifying and explaining a subject in layman terminology. Want to find any crystal forms of Corundum? How about a fibrous silicate? Even mineral terminology needs some deCoding at times. Bates and Jackson Glossary of Geology "It is not really a mark of distinction for a geologist's writing to be so obscure that a glossary is required for its comprehension." Jules Braunstein "Definition is that which refines the pure essence of things from the circumstance." Milton "A leader who is lost during the hike, was lost before the hike began and needs no encouragement from those who persist in following, by sharing information lost in the translation." Donkey Jenkins
  24. www.blm.gov/pgdata/etc/medialib/blm/co/programs/minerals.Par.44677.File.dat/Rockhounding%20Brochure.pdf Get the Rockhounding & Fossil Collecting BLM State brochure(s). Each area in a State can vary somewhat, so check in with each local or regional office. They KNOW what is going on for decades, so just ask... do not play stupid. For other State BLM Offices... inquire. Even the small local offices will provide you with information when you stop at the offices. There are also National Forest Service (NFS), National Grasslands, Bureau of Land Management (BLM), National Park Service, State Parks and Recreation.... and others. This example is for the Colorado BLM. Best local information: Local Rock Shop(s). They know everything that is going on in the area. They also sell books, booklets and maps at some larger shops. The "tourist shops" sell mostly Brazilian amethyst geodes and Morocco fossils... just kidding... but you know what I am saying. Nothing seems to be local at these shops and I haven't time to look at the same stuff you can buy in Tucson at the February shows.
  25. Hunting For Fossil Literature

    A typical Post on the Fossil Forum begins... "where can I find a book on (fill in the blank)? This is a very good way to BEGIN your search, but the Fossil Forum is a very diversified "collection of individuals". Members' interests may be focused or wide... but it is impossible to comprehend the large numbers of very significant references that are... as hard to find as the fossils anyone seeks! My approach to finding anything in PRINT, which is quickly being replaced with CD, Digitized or Pdf files. There are numerous sites to "search" for the topic you have an interest. The larger the book site, the more diversified the selection. Ebay: www.ebay.com Amazon www.amazon.com ABE Books www.abebooks.com State and Government geological websites Google Search www.google.com Institutional websites (Carnegie, Chicago Museum, Smithsonian, American Museum, etc., etc, etc.) Some organizations specialize: One for Foraminifera might contain 125 feet of hard bound books and going strong for the Petroleum industry. Saber Toothed Cats... maybe three feet of publications, if you are lucky. Geological Society of London, mostly Great Britain. Geological Surveys: example- United State Geological Survey for mostly USA subjects and some International work. You can also search Meddelelser om Gronland (printed in Denmark in English) for Devonian armored fish. Every country has a Geological Survey... or had at one time. Russian and Chinese geology had been only available in Russian or Chinese text. Today the Chinese also have English texts. So if you speak German... search in German. France... French. Many languages print theirs in English. Almost ALL Spanish speaking countries print in Spanish text... only. So the literature is diverse, you will learn HOW TO SEARCH various countries. Israel... mostly English text. The United States Geological Survey has a library in Denver, Colorado. The main floor is thousands of square feet and this is "some" of the material available to browse. They maintain material from all countries, institutions and whatever else might be of importance to geologists. If you have a USGS library in your area, visit it, browse the isles. It is overwhelming! Associations, Society and Institutional publications: Geological Society of America, Palaeontological Society of London, Geographical Society of America, Journal of Paleontology (Society of Economic Paleontologists and Mineralogists and the Paleontological Society), Palaeontology (the Palaeontological Association- London), Palaeo- Geography, Climatology, Ecology (An International Journal for the Geo-Sciences), Lethia and International Journal of Palaeontology and Stratigraphy (Norway), Japanese Journal of Geology and Geography (National Research Council of Japan), Geochimica et Cosmochimica Acta (Journal of the Geochemical Society- mostly Meteorites and Cosmic subjects) and.... on and on. Remember, British Palaeontology and American Paleontology are spelled with the "ae" and "e", so you sometimes must keep that in mind. The Hunt for information that you want: If you thought that someone knows WHAT book or short paper you really need for yourself... this is just the beginning of your search for knowledge. The more technical the subject matter, the shorter the publication! Some organizations specialize. A group that prints papers on Trilobites, will not have mammals. Crinoids will not be found in a book on Ammonites. IF, you want specialized information. Beginner books or Introductory to.... books: The more general a book, the less useful it will be to you once you have some experience. BUT, they sell more copies as many beginning collectors need a very general book. These are easily found at book shops or advertised for sale in hobby magazines... Rocks and Minerals, Gems and Minerals, Earth Science. The must be general to sell well. The more specific a book, the fewer copies that are printed. First Edition, Second Edition.... Twentieth Edition: Some beginner books are so poorly written, many mistakes are made in identifying a fossil, can be misleading and are often subject to revisions in... future editions. Some are offered in new editions as they correct the text and expand into other areas and provide more information. The First Edition of a general fossil book can also be in the Tenth Edition. You would want as late an Edition you can find. If you know there ARE later editions. They may cost more, but these are corrected and updated each time they are printed... BUT.... Edition and PRINTING are not the same. A new Edition is updated and corrected. A Third Printing is exactly that... the same book but reprinted once it is sold out and there is a demand for more copies. One exception to the first, second, third and fourth Printings would be Index Fossils of North America. They are all the same, unless I missed something. The first printing in 1944 is the same as the Eighth Printing of 1965 and so on. When it goes to the Second EDITION, then take notice it has been updated and any corrections made. **************** This is just a beginning. I have just scratched the surface but you now have the ability to seek and find a technical book that will be current for a life time. A mid 1800's technical volume might have been updated since then, since interpretations change and new discoveries change the geology and science. But, the first recognized identifications have priority to names... unless competing names exist at the same time and one is MORE correct than the other. Cope and Marsh come to mind in Western USA Dinosaurs and Mammals... but I wander. As time permits and if anyone has ANY interest in this Topic... I would be happy to explore those obscure papers that would add to your knowledge of your special interest(s).
