  1. Friends, I would like the experts to evaluate these photos and please say it is an original keichousaurus ? Tks Pics:
  2. Fossilized bone?

    Is this a fossilized bone? or just something else?
  3. Found this while digging up a flower bed today. Part of it looks sorta like copper, I scratched it with a knife and its a soft material. Then the sides look like a skin texture and the bottom and top look like the inside of a bone. I also found a piece of petrified wood in the same location. Just wondering if anyone knows what it is. Thanks A few more shots
  4. Leaf material?

    I found these few pieces in a Marl Stone mine in Popovac,and i'm not quite sure what can this be?A possible leaf material or something else?
  5. Newbie with an ID request

    Hi there! I'm new here although I've been into fossils since I was a youngster! I managed to grab the following example on the south coast of Kent in the UK which is known for fossilised wood and footprints and bones etc. I thought it might be a fossilised tree limb or small trunk. What do you think? Any guidance very gratefully received! Thanks so much
  6. Possible petrified apple

    This was found years ago by my mother in the Ozarks of Missouri in southeast Missouri, on the st. Francois river. Has been around me since I can remember. Any help would be appreciated.
  7. Fossilized nut?

    My daughter and I took our Husky down to the river (more like a creek in the summer) to play earlier today. The river is so low right now you're basically walking on a rock bed. I found what looks to be a small petrified walnut. I tried searching the net but couldn't find anything similar. The closest I found someone said it could be a type of sponge? The lines on it kind of curve around to the back to where it looks like it could have hung on a branch. I know nothing about fossils but we have found a few from just being out hiking. We found what we think is a petrified deer tooth a few years back. I was able to id it online. This little nut thing is definitely wierd and I can't seem to id it. I guess it could just be a rock that's grooved up from wear. If I had to guess it's some kind of fossil though. Any ideas? Thank you for the help.
  8. Mussle Shell Steinkern

    This is a particularly fragile type of shell, made of many fine layers, and is prone to disintegrate as these did. This rare steinkern was found on a block of matrix submerged in the Chesapeake Bay. Dimensions are for the best-exposed steinkern on the block. The entire block is 14 cm wide x 10 cm high x 5 cm deep.
  9. professional fossil prep

    Hi - thank you to all that have helped me to acquire so much information on my fossils/concretions. How would I go about hiring a professional to prep some of my larger bone fossils? I assume it would be very expensive and would like to know if it's worth the time and money. I posted several photos in the ID section under the title "Bone or Concretion" and "is this a sea lion". If needed I can resend to this post. Thank you for your continued help and knowledge... very much appreciated!
  10. Various shark teeth?

    Hi, so I found a little Altoid tin at my dad's of what looks like shark teeth. There also appears to be some tiny vertebrae. I have no idea what they are or what they're called. They appear to be in really good shape. Any help is greatly appreciated! Thank you!!
  11. Definition of a Fossil

    So, here's one bound to start arguments, but how would you define "Fossil?" I was looking at a children's book the other day, and it was trying to differentiate a modern sea shell sitting on the beach with a fossil. It said that a seashell was not a fossil because it was not embedded in rock. By that definition, the vast majority of what I have in my collection is not a fossil because it was never embedded in rock. In Calvert Cliffs (Maryland), Big Brook (NJ), The C and D Canal (Delaware), Peace River (Florida) and other locales, the matrix is packed sand if not outright loose sediment. So, by this book, they are not fossils. Another definition I saw said that a fossil had to be in stone or replaced by another mineral. I'm not 100% sure, but aren't Pliocene fossils frequently not replaced by anything, just a bit leached and/or filled in from the surrounding matrix? Maybe I'm wrong on that point. A third one I saw said that it had to be at least 10,000 years old. I will challenge this one with the case of Saratoga, NY. The springs there are so heavy in minerals that they create STONE casts of the leaves that fall on the-ever-growing mineral domes in a matter of days. A cast is thick enough to peel off the leaf in a few weeks. The domes are riddled with hundreds and thousands of leaf impressions. If this is not a fossil now, what would make it a fossil later?
  12. Our Fossilicious Summer

    WHAT WE LEARNED IN OUR FIRST FOSSIL HUNTING SUMMER This is a short recap of what we learned on our fossil trips this summer, in our first 3 months as very new fossil collectors. This week, Nancy and I gave a slide presentation on our summer fossil hunting experiences, to the Delaware Valley Paleontological Society. We didn't realize it ourselves but in 3 months we visited 8 sites in Pennsylvania and New York including: Antes Creek, Deer Lake, Red Hill, Juniata County, McIntyre Mountain, Montour and St. Clair in Pennsylvania, and a very productive trip to Tully, NY. We visited St. Clair 4 times, which has become our home site. At St. Clair, we were astonished by the diversity of species - we collected well articulated samples of more than a dozen species including: Alethopteris, Annularia, Asterophyllites, Cordaites, Cyclopteris, Eusphenopteris, Lepidophylloides, Neuropteris, Odontopteris, Pecopteris, Sphenophyllum, Sphenopteris, and numerous Seeds, Bark, Roots. Most notably - I learned to pronounce all of these without stuttering! At St. Clair, we spent one trip looking exclusively for seeds trigonocarpus), and one trip looking just for roots (stigmaria). Our most significant finds have included very large (2 foot long) display pieces covered with well articulated orange ferns, an alethopteris seed attached to a leaf stem, and many Carboniferous leaves that have different shapes from traditional ferns. What we learned this summer has really helped us find some interesting fossils - here are a few things we did that helped a lot: 1. DOING OUR HOMEWORK. It helped to study each site in advance using Internet websites and books on fossils (Dave's "Views of the Mahantango" and "Louisville Fossils" are among the best, imho). Several universities also have great educational sites that bring each era to life in very creative and interesting ways, with lots of illustrations and photos. I like the UC-Berkeleyand University of West Virginia websites. 2. LEARNING FROM TRIP REPORTS. We read trip reports from other groups and individuals to see what they reported - sometimes this helps us stumble across new places to visit such as the site at Tully, NY and Deer Lake. 3. SETTING GOALS AND TARGETS FOR EACH TRIP. For each trip, we establish specific goals - for example we may look for seeds, or roots at St. Clair, or trilobites or shell assemblages at a Devonian site. Our interest right now is in looking for things that are scarce or rare, and fossils that are extremely well articulated (which is also rare!). We also like solving puzzles so eventually we would like to find things that help add to the fossil record in areas where there are still questions or missing links. 4. DISPLAYING WHAT WE FIND. Personally, Nancy and I like collecting larger fossils that we can display in mounts and frames, and we are also looking for larger pieces that we can display like sculptures - we have a few pieces that we drilled holes in, inserted wooden dowels that we stained, and then drilled/inserted the dowels in wooden trophy bases - all available from a craft store. This allows us to display thicker fossils esp. assemblages, like sculptures, and you can turn them around and look at all sides when they are mounted like this. 5. WE AVOID FOSSIL HORDING. We both agreed that we would NOT become "fossil horders" putting hundreds of rocks in boxes and sticking them away in the basement or garage - instead, we focus on finding display-quality items, and rare or scarce finds which we are slowly putting in frames. 6. DOCUMENTING OUR FINDS WITH CLOSEUP PHOTOS. We photograph everything we find as soon as possible after returning from a trip, using a digital camera with a closeup attachment - many times we find new discoveries while taking closeup photos and some of our best finds came AFTER we returned from the trip and inspected our fossils. I usually put the finds on a white background on an ironing board and use window light, nothing fancy, but it works. 7. FOSSIL ID. We post anything we can't identify on the Fossil Forum and are EXTREMELY grateful for the terrific response from our friends on the site! We are also accumulating a growing library of fossil books (some modern, some from the 19th and early 20th century) so we can identify more fossils ourselves without having to post on Fossil ID. 8. WRITING ABOUT OUR EXPERIENCES GIVES US NEW INSIGHTS. We report everything that interests and excites us about fossil hunting on Fossil Forum to share our experiences - and we find that writing about what we're doing helps us learn more and gain insights, just from writing about it. We have also started videotaping some of our adventures and are thinking about the best place to post some of these. 9. WINTER PLANS: COPING WITH CABIN FEVER. Our winter plans are to visit one or two more sites, then go into "fossil hibernation" and organize, identify and label fossils we haven't processed yet. We have a Dremel to do some light preservation work where needed. We are not planning to become "chemical conservators" - using chemicals to dissolve limestone and so forth - that's a bit too ambitious for us at this point. We may get involved in some interesting activities by local universities that are using 3D printing to process and replicate large dinosaur bones. We are also planning to provide an exhibit (on Carboniferous plants and trees/coal swamps) at a fossil fair in April. 10. RECOMMENDED READING: I enjoy reading fossil books - I'm currently reading with great interest a small book entitled "Leaves and Stems from Fossil Forests" by Raymond E. Janssen (1939) which I bought last night at the DVPS meeting, and a textbook entitled Introduction to Paleobiology and the Fossil Record by Benton and Harper (2008) (excellent book). The book that has been the most useful to me so far is the classic book "Fossil Collecting in Pennsylvania" by Hoskins et. al. (3rd ed. 1983). I am constantly re-reading the Hoskins book and find something new each time as my knowledge grows. A book that impressed Nancy and me is a large beautifully illustrated book entitled "Prehistoric Life: The Definitive Visual History of Life on Earth" (published by Dorling Kindersley, 2012) UPDATE (Oct 11): Nancy is taking some college courses which are prerequisites to enter grad school, so I am doing most of the fossil reading and ID. I read several books at the same time and other books I purchased that I am currently reading are: Paleobotany: The Biology and Evolution of Fossil Plants (second edition) by Thomas Taylor; and Introduction to Paleobiology and the Fossil Record by Benton and Harper. I guess you can tell from this that I'm reading up on fossil plants - my main interest is not just to understand the evolution and fossil record, identification tips, etc. - but also to try to figure out where the missing links and gaps are so if we come across something that adds to the fossil record, we will be able to recognize the value. What is most surprising is that there is a lot missing from the Carboniferous record - partly because after this period, many of the oceans and swamps apparently dried up and there were ice ages and other factors that caused mass extinctions. Here are some interesting things I have learned this summer about Fossil Plants and Trees: 1. More Carboniferous insect fossils and evidence of insects are needed (by the way, there are some GREAT current discussions about insects on this forum!). 2. Many categories of lycopsids and other Carboniferous trees and plants do not have verified associations between the leaves and seeds, or leaves and trunks/stems. Many trigonocarpus (fossilized seeds and "fruits") are found with leaves, but examples of seeds actually ATTACHED to leaf sprigs are rare (we have found one example of a seed attached to Alethopteris). 3. More Leaf and Bark Verifications are Needed. Another interesting thing I learned is that there are more than 30 different types of "scale tree" patterns but only half a dozen leaves for these trees - suggesting that a lot of different species had the same leaves - or - there are a lot of missing leaf types or the existing leaf types have not been matched to the bark patterns yet. 4. Another peculiar revelation is that most Carboniferous leaves that do not fall neatly into classic fern shapes seem to be lumped together as "sphenopteris" - we have many "non-traditional fern" leaf fossils that are VERY different from each other and obviously different species, but when we go online to ID them, they all seem to be grouped as "sphenopteris!" Maybe some of these leaf types match up with the bark patterns I mentioned. 5. Last but certainly not least is the insight that fern trees could have 2 or 3 different types of leaves on the same tree! This was really interesting. Also, some leaf types can come in different shapes - for example, Neuropteris can be round at the base of a stem and elongated along the stem and at the tip...AND...some paleobotanists now classify cyclopteris - the round fan shaped leaf - as a form of Neuropteris. This definitely adds to the confusion. I'm still reading and trying to understand all of this and these are only my initial impressions, which are still forming and there may be explanations for some of these questions that I haven't discovered yet but these are the questions that I am trying to answer by reading, and of course, by fossil collecting. I hope that many of our new friend (and I should add, VERY COOL new friends!) on the fossil forum will help clarify some of these interesting questions. Hope this is helpful.
  13. Shark Trace Fossil

    There has been much debate about the identity of this strange item on the forum. I finally solved the mystery thanks to the (click next) Calvert Marine Museum web site . These are a reasonably common find on the beach near Matoaka Cabins. They vary in size and shape, owing to the different species and ages of the sharks that produced them as much as the teeth shed by the same sharks. What they all seem to have in common is the black, polished surface, the generally oval shape (which can vary in proportions), and the appearance of an outer coating that splits on one side.
  14. Found this in the water on the beach in Omiš, Croatia. There are three prominant dark curved lines across one of the surfaces. Dont know if its just a rock or if its something else?
  15. Barnacle

    Found on the beach near Matoaka Cabins. This is the largest one I have found to date.
  16. Short trip

    Me and my brother decided to go looking for shark teeth at our regular spot but road ended up being closed and we ended up at another spot along the river. I heard there were fossils there, so we decided to try it because we only had a few hours. Ended up being a nice trip. Can't wait to go back. Can anyone tell me more about these. How old are they? <img> <img> <img>
  17. Some of it is eroded so makes it a little tricky. I've come up with the following so am humbly requesting anyone who is able to verify or correct. Thanks. Kingdom: Animalia Phylum: Mollusca Class: Bivalvia Order: Veneroida Family: Mesodesmatidae Genus: Paphies
  18. Fossil?

    Found in Raubsville Pennsylvania
  19. Desert find

    I found this piece out here in the NM desert while walking our dogs.....we are the only ones that live out here so I'm not sure how this got here...or has it always been here under the sand?Can anyone tell me if this is anything?It looks like a turtle egg but is solid
  20. Bone piece ?

    It is bone? Age: Miocene Location: Southern Poland , Kraków area .
  21. Miocene whale bone ?

    Hi This is whale bone ? Age:Miocene Location: Kraków , Southern Poland I found the whole bone - jaw? Unfortunately, I was able to extract only this piece. This specimen falls into the hands and therefore remains in the rock. Do you confirm this?
  22. Found in raubsville Pennsylvania
