  1. Took a trip out to South Carolina today to visit the Campbell Geology Museum! It wasn't big, but honestly I was surprised by how many really cool specimens they had. Pictures to follow:
  2. What is it?

    Finding a lot of fossil wood this past week. Agates to for carving. The bedrock underneath the gravel at Stillwell Ranch is limestone packed with fossils. Mostly Rudist. Then there are enigma. This stone has the blue infill, I associate with one type of fossil wood preservation. I thought it was a cluster of horn coral initially. But they don't pack up like this. No septa at all. Just finger length long ovals, width of your big toe...........The best detail are the onion layers which are micro crenelated. The end photo seems to have bisected a number of the lobe features. I think they were long and egg shaped un-eroded. With a hollow cavity in the center that was filled with blue & white chalcedony. Chime in if you have a good idear or two of what this is.:
  3. Hi, Bit of a geological question here, I recently took this photo of some of the Upper Hamstead Member strata exposed on a headland at Bouldnor Cliff whilst out collecting. I really like this spot as the colour variation in the beds is really interesting. I've heard that the colour mottling in mudstones such as these can be indicative of the paleo-environmental conditions they were deposited in. Generally speaking these muds were deposited in ponds, lakes, and sluggish waterways on a low lying coastal plain. However, would it be correct to presume the redder areas indicate more arid conditions i.e. a period when the Hampshire Basin coastal plain was very dry and the other green and grey beds periods in which the environment on the plain was wetter? Thank you, Theo
  4. Herrick on Herrick

    "Our laboratory was the geologic wonderland of New Mexico; our problems anything and everything which the face of that remarkable region presents to the student of earth history. The lecture platform was one end of the wagon seat, the shaded ground under a juniper tree, or the ragged wall of an igneous dyke. My student's desk was the other end of the wagon seat, a rock in the shade, or the bank of some arroyo. The hours were from daylight till long after dark, the discussion endless, and the themes were notebooks filled by the shifting light of the campfire. Under the stars of New Mexico's matchless sky I listened to a great man discuss evolution, magmatic segregation, stream erosion, and as the dying fire sunk to glowing embers and the stars shone more brightly I listened while the scintillating mind strayed into those fields of psychology and philosophy he loved so well, and heard him expound the principles of dynamic monism." -Douglas Johnson (field assistant) Clarence Luther Herrick: Pioneer Naturalist, Teacher, and Psychobiologist
  5. Geologists matching rocks from opposite sides of the globe have found that part of Australia was once attached to North America 1.7 billion years ago.

  6. Trilobase Users question

    Hey Trilobase Users. Finally, decided it was time to seriously address cateloguing my fossil collection. I just started using the Trilobase program, so I'm still on a learning curve. So far I like many of its features, however, the Geologic Section for the Collection Site information does not seem to have a designated spot for including the site's geologic formation. Since the geologic formation is important information for a fossil specimen, this seems to be an oversight. I'm curious how you users have dealt with this issue? Please let me know what you have done to resolve this issue. Thanks
  7. Hello, I am a student at Centralia Community College working on an identification / analysis of fossils from the Clarkia Formation. I was wondering if anyone here has worked on this formation? If so, do you have any advice on how to properly set the sediment they are in to limit breakage/crumbling? Thank you! ~ AQM
  8. NC during the Pleistocene

    I'm curious as to what North Carolina was like during the Pleistocene. Does anyone know if there are any references specifically addressing this time period for NC or the Southeast? It is my understanding NC was not covered by glaciers. Is there any reason why Pleistocene aged fossils could not be found in most areas of the state? Any information or resources would be appreciated.
  9. 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?
  10. 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.
  11. 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!
  12. 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
  13. 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.
  14. 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,
  15. 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/
  16. 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!
  17. 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/

  20. 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.
  21. 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
  22. 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!
  23. 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.
  24. 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.
  25. 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.
