  1. Florida Fossils

    I found some fossils this weekend that I found on a creek along the Peace River. There were three bones that I needed help identifying. The first appears to be a toe bone. I was kinda thinking horse, but it may be too small. The second is a jaw bone. I believe it may be a racoon, but not sure. The third item looks like a claw. My guess is a giant tortoise spur, as I'm not sure what else looks like it. Any help would be appreciated.
  2. mammal bone id

    I have seen nothing like this bone before and have no idea how to start attempting to identify it. I've been through the gallery of @Harry Pristis and seen nothing there. I can't tell how complete it is, but I think there are some good diagnostic features there.
  3. Clacton find

    Hi, this is a find from high up the beach in the dry sand found 50m east from Clacton pier, I dont think its bone or ivory, it was in two pieces when found so I stuck them together, a lot of material from the Pleistocene and before found in this location due to the beach recharge, Bison horn?, any help with a possible ID would be great, many thanks.
  4. Hey guys, The wifey found this one. Turtle or bird? And what bone? Cheers, ash.
  5. Great variety today. I’ll add more pics tomorrow but just had to get this piece uploaded tonight. I’m almost positive this is capybara. I only hesitate because I have not found any other capybara material on the Brazos River. Needless to say , I’m pretty stoked with this find!!! Will definitely be entering this in FOTM!!!
  6. Pleistocene Tooth , What is it?

    Tooth of Unknown animal from Pleistocene deposits of Cyprus. I thought it was the tooth of the extant species of dwarf elephant. What is your opinion?
  7. Whale vertebra?

    I was in a Texas museum yesterday and was looking at a case of primarily pleistocene fossils. This vertebrae was labeled mastodon, but really doesn't look like any mastodon vertebrae that I've seen. We don't generally find whale vertebrae where i look for fossils, but this hits me and I definitely don't know whale, as possibly whale? Vertical thickness is approximately 4-5 inches, 10-12cm. There is no other labeling other than mastodon. Sorry for the quality of the photos, dark lighting and a hand held camera.
  8. La Brea Tar Pits Bone Fragment

    Here’s an interesting one. I docent at the Page Museum at the La Brea Tar Pits, and while I was talking to some visitors one of them gave me a piece of bone fragment his father found (among many other easier to identify pieces) at the tar pits before the museum was created. I have showed to some of the researchers at la Brea, and their guess was that it was a tibia fragment from some mammal. So far based on my own comparisons, it seems closest to a dire wolf, but if anyone else has any other ideas, I’d love to hear them. Thanks!
  9. I had a fun hike at the North Sulphur River Texas yesterday. I figured it would be picked over but I found a pretty remote spot with my 4x4. The one sawfish tooth I found in a small creek a few days before. Everything else is from yesterday. It was a great day for Cretaceous coprolite (Poo). @GeschWhat The one coprolite is full of fish verts, bones and fins.
  10. Unknown Impression?

    Im really not sure what this could be. It was found yesterday in 2 million year old fransician muds at Centerville. Im thinking some sort of plant impression. Or maybe a fragmentary piece of sand dollar which are known from this locality aswell.
  11. https://www.dailymail.co.uk/sciencetech/article-6755503/Ancient-tooth-extinct-four-metre-sloth-Belize-reveals-creatures-days.html
  12. Mammal vert

    This may be a long shot. Can anyone I’d this vert I found on the Brazos River in Texas?
  13. Tooth ID from TX Gulf Coast

    Found this mammal tooth on the beach in Galveston. Any ideas what this tooth came from? Thank you.
  14. Encope borealis (A.H.Clark 1946)

    From the album Echinodermata

    9cm. Sand dollar. I'm assuming that this comes from Pleistocene layers somewhere in Mexico. The seller had no idea, but fortunately the friends here in the forum did.
  15. Encope grandis (Agassiz 1841)

    From the album Echinodermata

    9.5cm. Sand dollar. I'm assuming that this comes from Pleistocene layers somewhere in Mexico. The seller had no idea, but fortunately the friends here in the forum did.
  16. Mellitella stokesi (Agassiz 1841)

    From the album Echinodermata

    9.5cm. Sand dollar. I'm assuming that this comes from Pleistocene layers somewhere in Mexico. The seller had no idea, but fortunately the friends here in the forum did.
  17. Teeth found on a beach

    Hello, A few years ago me and my daughter found this tooth on the beach in the Netherlands. Since then we started to go regularly to several beaches to find washed off treasures. I though one of them was a horse tooth from the pleistocene...now i am not sure..it's too compact and short..i would love to have your expertise on it
  18. Hey all! This week my colleagues and I published a paper we spent most of the last decade sweating over. It is an exhaustive report of all known late Miocene-Pleistocene records of teeth of Otodus (aka Carcharocles) megalodon teeth from the west coast in an attempt to estimate the date at which O megalodon went extinct. Aside from some conspiracy theorists who will wait until they die and not see a live 'meg', we all know it's not living today as there is not a shred of positive evidence indicating its existence. We know it's around in the Miocene, and the early Pliocene. Did it survive into the Pleistocene? End of the Pliocene? or become extinct sometime earlier? These questions require serious thought because it has direct implications for whether or not O. megalodon went extinct at the same time as a bunch of weird marine mammals or if it was killed off by a supernova known to have occurred 2.6 Ma. An earlier study pooled fossil occurrences from around the globe and statistically reconstructed a mean extinction date of 2.5 Ma, with significant error (~3.6 Ma to 100ky in the future being the max and min extinction dates). We found that in the California record, reliable occurrences are only found in early Pliocene rocks. All examples of late Pliocene or Pleistocene teeth were either poorly dated, reworked from Miocene rocks, had poor provenance, or are completely missing (and never photographed) and therefore the identification cannot be confirmed. We thus predicted a 3.6 Ma extinction date. To test this, we re-analyzed the dataset published in 2014 but chucked a bunch of bad data and exhaustively re-researched the stratigraphy of each locality and corrected about 3/4 of the dates in the remaining dataset, and added our new California records. When we analyzed this corrected dataset, our margin of error (the time between the max and min extinction dates) shrank from 3.6 million year long interval to 900,000 years; *probably* extinct by 3.6 Ma (mean extinction date), definitely by 3.2 Ma (min extinction date), and possibly as early as 4.1 Ma (max extinction date). This extinction therefore precedes the 2.6 Ma supernova, as well as the Plio-Pleistocene marine mammal extinction (which in all likelihood was not a mass extinction or an extinction event, rather just a period of higher extinction/origination rate). About 4 Ma is when fully serrated Carcharodon carcharias teeth show up in the North Atlantic, indicating when the two overlapped, however briefly. We think this biotic event matches best - the mechanics of exactly how this was driven are to be figured out by someone else, but perhaps adult Carcharodon outcompeted juvenile O/C megalodon prior to becoming gigantic. Some analyses of Otodus lineage growth rate is going to be necessary. Here's the open access paper here: https://peerj.com/articles/6088/ Here's a blog writeup I did for PeerJ here: https://peerj.com/blog/post/115284881293/early-pliocene-extinction-of-the-mega-toothed-shark-otodus-megalodon-boessenecker/ Excellent summary in Nat Geo: https://www.nationalgeographic.com/science/2019/02/megalodon-extinct-great-white-shark/ CNN: https://www.cnn.com/2019/02/14/us/megalodon-extinct-earlier-scli-intl/index.html Fox News: https://www.foxnews.com/science/megalodon-shocker-huge-killer-shark-may-have-been-wiped-out-by-great-whites Forbes: https://www.forbes.com/sites/melissacristinamarquez/2019/02/14/great-white-sharks-may-be-the-reason-why-giant-megalodon-shark-is-extinct/#6a06986a6486 Daily Mail: https://www.dailymail.co.uk/sciencetech/article-6700495/Giant-50-foot-long-predatory-shark-went-extinct-one-million-years-earlier-previously-thought.html

  20. Fossilized Arizona Human Footprint (?)

    Let me start this off with two disclaimers: 1- I am sorry if this post would be more appropriate on an archeology forum. I would think that it would be fine here, however, because the "footprint" impression does appear to be fossilized. And because I have yet to join any archeology forums. I anyone has a recommendation for a good archeology forum let me know. 2- Being almost entirely engulfed in learning about just the Cretaceous of my local area, paleoanthropology is a bit out of my purview. So bear with me if I sound like I don't know what I am talking about. Because I don't. I feel more comfortable with ammonites and Ptychodus. On Wednesday night my mother brought to my attention a post by a Facebook friend of her's, Kevin, who was recently out leading a group of 4-wheeler enthusiasts along some extremely remote Arizona desert trails when he happened upon what appears to be a fossilized human footprint. He really enjoys the rugged beauty of the deserts of the southwest and has been leading groups on such 4-wheeler outings for many years. Because he doesn't have a TFF account and because his Facebook page is private, I am posting this for him. I don't know if this is a real print or, even if it is, that it would be a significant find. I just thought that it wold be appropriate to check with TFF now before it eventually erodes away, just incase it is important. My mother has been friends with Kevin on Facebook for years, and his association with our family goes back to him knowing my great-grandparents at their church in Parryton, Texas decades ago. From that long association, he seems to be the type of person that has neither the inclination or time to be faking tracks. His interest is in exploring the desert, not perpetrating weird hoaxes. My concern is not that he faked it, but that perhaps some other unscrupulous person, apparently with a lot of talent, came along the trail and did it. When this fossil piqued my interest I asked him if I could post this to a fossil forum that I belong to and he gladly allowed me to, saying that he hopes to learn as much about it as he can himself. During our conversation, he also said that he found it, "out in the middle of nowhere near Quartzite, AZ." Along with the pictures of the impression he wrote, "While I've seen several dinosaur footprints this is the first human one I've seen preserved in sedimentary rock. I'm always amazed when I think of all of the circumstances that had to come together for this to occur. Of course, I have no idea how old it is. I have been under the impression that Native American tribesman that might have roamed these area were small people, partially based on the size of the doorways in dwelling I've been to in Utah. This print is an adult and looked to be about a size 10 [about 25 to 28 cm long]. Perhaps this is older or more recent. No telling. But still impressive." To my untrained eye I don't see any obvious signs that this is faked, but I would like to know what you think about it. His didn't indicate the presence of any other tracks in the area, so either he missed them, the others are already weathered away, or more are still buried. Again, my knowledge of paleoanthropology is still wanting, but from reading theses articles (here, here, here, and here), I gather that human tracks in North America are rare but, as I see from the first article, they are not unheard of in Arizona. The first article is on a multi-track site just north of Tucson. And from the pictures in the articles, Kevin's would seem to be a very well preserved specimen if it is real. Interestingly, Mancos shows that the geology around Quartzite is very similar to that just north of Tucson, even though Quartzite is about 200 miles to the northwest of Tucson. The geology around Quartzite and Tucson is mapped as Quaternary surficial, with the age range listed as from the Gelasian (1.8 Ma) to modern holocene. Here are the only two pictures of the impression that he posted, along with his pictures of the surrounding scenery of the area. I am also including pictures of the Mancos map of the areas around Quartzite and Tucson. Hopefully the pictures are enough to at least say whether or not it is worth further investigation or an obvious fake. Thank you for your time. Fig. 1 Fig. 2

  22. I found this today while I was out seeing if I could find more pieces of my bison. It was at the same level as the bison, but about 30 feet down the creek. It is turtle or tortoise, but I’m not sure what kind or if it is modern or Pleistocene. I looked through a Texas turtle database and did not find a match with any listed there. So it leaves me wondering if it could be an extinct variety. The shell patterns are so distinctive I’d think it could be ID pretty close to what it is. Here are pics. Any thoughts or or comments would be appreciated.
  23. This comes from Centerville Beach, Humboldt County California. I've found alot bivalves and snails in the cliffs where I found this. Another Formation 5 miles away has had reports of turtles, shark and marine mammal teeth and even agatized whale bones. I'm sorry about the quality of the pictures. I do not currently have a very nice camera. Its sticks to my tongue and has a rough porous surface. The divet on the right side of the bone in the first picture is a place where is has apparently broken.
  24. Fossils and Magma

    Hey guys. In NZ we have quite a few volcanoes, and luckily for me living in christchurch, the most recent eruption in the south island was about 20 mya. On the "vanished world" trail, there is a preserved basaltic volcanic dyke/sill that has been injected into the strata beneath an ancient lagoon. While I'm aware that these magmatic intrusions don't break the surface, there is a broad fossil horizon not far from the top most termination of the sill, with beautiful small spirulla (?) (Some kind of elongate fossil snail) preserved in the rock. I was wondering, that as I mentioned before that this fossil horizon is not too far from the intrusion, just how much heat or mineral replacement does it take for igneous rocks the the associated hydrothermal minerals to completely destroy/deform/disfigure fossils in these kinds of geologic environments? I have included a rough sketch. Like all great geologic exposures, it occurs at a public road cutting, to provide context.
  25. Cave Lion - New look!

    Hey everyone! Here is the new look of the Cave Lion! With smaller mane as u see. This is something new for me,to draw animal in the other position.Also, at the end of the paper is a bison skull, example of his diet. Enjoy Darko
