Hi all, I'm a newbie to the forum and fossils in general, so need all the help I can get! Found this on the coast in the UK today. It appears to be the fossilised end of a limb bone. It's heavy, nearly a 1lb, and is as hard as rock. It's 4.5 inches long (11.5cm) and 2.5 inch widest. Any help from the keen fossil minds on this forum would be fantastic.

I found this chunky bone end fragment in sandy gravel matrix, Pleistocene era. This may be a chunkosaur, but since there are at least a couple of possible identifying characteristics here, I'm hoping that someone with more experience than I have could help me narrow this down. Didn't seem to fit calcaneus or astragalus, but it does show a groove and two points on one side that are pretty well defined. Image One: Flat face Image Two: View of taller side Image Three: View of shorter side

Found in Creek stuck in wall sediment by Corpus. Was next to arrowheads I will do burn test soon but it might be only 5 - 15,000 years old so I dont know if it will pass

Hello everyone, My name is Tim and i currently work as an archaeologist in the Netherlands. Specialty: middle ages. I also excavate other periods like the paleolithic - Neolithic, metal era's and all other, but the middle ages are my favourite. Also scuba diving is a beloved hobby. I dive in the Netherlands and during the summer along the French, Croatian, Spanish and 1 time Cornish coast. In England we only had 1 day of dry weather in august.. During my dives i'm allways searching if I can find man made objects or fossils (I have found only 2 shark teeth fossils this far) Beside this: I'm allways on the lookout for fossils. As a kid I always picked up every stone hoping it had a fossil in it. And when I grew older. More picke up stones contained fossils. On the Dutch coast and in the fishingnets I searched for Pleistocene fossils, like bone fragments, fish or shark teeths. I also searched for cretacious fossils in France (Cevennes) and Lime Regis, England with my american & english hammer and chisel/opinel knife. Most fossils I have are the ones I found in France. Ammonites and belemnites. And pleistocene fossils from the coast. I hope to see and learn a lot on this forum! Tim

Hi all, I'd appreciate any input you have on this piece please. I bought a lot at auction only labelled 'North Sea Pleistocene'. I live in the UK, so there's a fair bit of coast that can get North Sea fossils washed up, usually nowadays seems to be Norfolk area - unfortunately I have no way of knowing whether that is the locale. This measures 170x100x50MM approx at its longest/widest points. I suspect its from a sort of deer/small horse sized mammal but don't really have any further ideas. It could have broken off something larger. Thanks in advance for any input! John

Found these teeth recently along the Peace River in Florida. Was curious what species these may be from. Any help would be greatly appreciated.

First million-year-old DNA extracted from Siberian mammoth teeth

Hi All, I am new to this forum. I am over my head in what is, in my novice opinion, a preponderance of quartz stone tools that go back to the Pleistocene. Among the unverified relics, I have found a variety of bones which appear to have been altered for use as tools. Additionally, they have what appear to be teeth marks at the edges, as if a person was holding them in hand and biting. I wanted to post a pic of a rib that I think belongs to a Camelid. I have spent a lot of time looking over pictures of all sorts of mammal ribs, and Camelids come the closest. Additionally, I viewed a post on this site where a person posted the exact same bone, and said a expert told him it was probably a Camelops. Notably, this bone has had the vertebrae side sawed off. It fits in hand perfectly to accommodate waist level thrashing. If these are teeth marks, it seems possible it was done intentionally to give the rib more of an abrasive blade for thrashing. Speculation aside, positively identifying this bone will at least give me some confidence that I am (or am not) in the right period of human history. Thanks for your help!

Galveston Bay dredge spoils, Beaumont formation late Pleistocene. Collected this vertebral epiphyseal plate this afternoon. Based on size and shape I'm guessing a proboscidean?

Tube-shaped marine fossil/junk/artifact from Brazos feeder
jtangandgorditi1994 posted a topic in Fossil ID
Found this on the surface in a Brazos River feeder creek near Houston. It was not near any known exposure, but the Brazos itself transport marine Eocene and Paleocene from up north. It also erodes out Pleistocene bone pretty often. The bank of this feeder creek was sandy with clay underneath. One end of the cross section appears to show something organic within. When looking in from the empty end, the cavity wall is rough but doesn't look like bone-porous. Lick test of the outer surface is positive, noticeably, which makes me think this is marine. Overall, the segment is 1" in (outer) diameter and 1" long. I am still novice at fossil hunting, but this is entirely unfamiliar to me. I would guess baculite or horn coral, but only the because of the shape Any ideas appreciated!!!

Florida Gastropod Identification Help (small - less than 1 cm)
Gregory Kruse posted a topic in Fossil ID
Hello, I found these gastropods in north Cape Coral, FL. They were in a pile of shells being used for landscaping so I presume that the sediments came from a nearby quarry of ?Pleistocene age, possibly the Caloosahatchee Fm. Can someone help me verify and identify these fossils? Thank you!

A group of UK scientists reexamined a group of late stage Neanderthal teeth from the early 1900s with modern techniques such as CT scanning. They discovered a mix of new characteristics indicative of both modern Homo sapiens and Neanderthal, more evidence supporting a gradual absorption of Neanderthals into emerging modern human populations.

Anyone know of or have information on Gomphothere Ivory Schreger angle?

I was hunting the Peace River on Wednesday and up came this bone that seems to have enough features to be recognizable. In the 1st photo, long bone coming in from right; in 2nd photo from left... Yesterday, I moved to a pre_pleistocene location, with mostly Blancan fossils. Found this one about the same size and once again with features that should be recognizable. So to start, I am just trying to determine type (Femur, Humerus, Tibia, etc). Certainly, let me know if you recognize the species, but even type of bone would give me a starting point...
