While playing with my poo (the fossilized version), I noticed this imprint. It is adjacent to a bone fragment. I'm assuming it is the imprint of a piece that broke away from the bone inclusion. It looks a bit unusual/ornamental, but I am hoping it is recognizable to one of you brilliant bone folks. This is from the Oligocene, Brule Formation, South Dakota. @Carl

These two mammal teeth were found in northern Florida, I dont know what formation they were found in, but they are probably from the Pleistocene. The first tooth is about 3/4 of an inch long, and about the same in width at the widest point. The second tooth is about 1/2 an inch long and about the same in width at its widest point. They appear to be herbivore but I could be wrong, I'm not good with mammal teeth yet. Thanks!

What was for supper? Did they love meeces to pieces in the Oligocene?
GeschWhat posted a topic in Fossil ID
Since I couldn't go out to dig for fossils, I decided to go on a micro dig. Today's dig was in a coprolite fragment from the Oligocene. Prior to excavation, the broken face of the coprolite looked like this. You can see a little bit of bone peeking through. After about an hour of excavation under 40X magnification, I uncovered what I think is a rodent tooth and possibly a toe bone and claw??? What do you think? Does anyone out there know their Rupelian rodents? Grinding Surface of the tooth: Side view showing roots: Small toe bone and claw or an fractured toe/foot bone? Is fossil poop cool or what???

Here are a few specimens that have been poo pooed by collectors. As I understand it carnivore coprolites like this need a "soft landing" They are produced in water and sink into the silt where protected as they fossilize. The holes are caused as the item surfaces and is exposed to the ocean tiny bivalves attach themselves to obtain minerals. Many have holes only on the side that was exposed. And others have no holes at all having never been in the ocean. The natural migration of barrier islands on the east coast is to move to the south west, this action is like a bulldozer track as the top moves west and south the contents sometimes appears on the beach surface. Most fit into a specific type and all are smaller than a big dog, more like a cat or small dog sized creature, but none bigger. if they were a type of Coquina there would be larger specimens, there are none. There are however all sizes and types from different periods of Coquina from tiny pieces to hundreds of pounds. There is evidence of shell fragments and often it appears the sample has landed on decaying vegetation or partially wrapped around a stick. I even have one that has fragments, a termination point, obvious vegetation impression on one side and a foot print on the other side. I have pressed a piece of clay in to each side as a reverse study. In the first picture he foot print is less obvious than the vegetation impression. But when the excess is removed it reveals a triangular webbed clawed print.

Hi, Even in this hard times of corona virus outbreak I couldn't resist the urge to visit again a cave that I found a few weeks ago, but couldn't explore it fully. So I went again and this last time I went in the cave I found a great number of bones scattered around the cave. I think they are probably modern, but it is weird because the cave isn't very easily accessible for animals since it has a few big drops. I found this tooth in a small ,,room,, which was barely big enough to squeeze in to. In that same place there were a small broken skull and many bones, but this is just one of the many places with such bones. At first I even thought that some explorers ate a chicken or something like that in there, but the bones are just too many and THIS WOULD HAVE BEEN A CHICKEN SLAUGHTER FEST. I would be glad to hear your opinions on what creature is this toot from and if it is modern or ancient. The color I guess would suggest modern but i am no expert on how are bones preserved in caves and sadly I have no information on the age of the cave. I hope you are all fine and the virus never gets to you!

I recently found this mammal tooth along Peace River in Florida. It is just the cap of the tooth with no root present. I'm having trouble identifying it and was hoping someone would recognize the tooth and what animal it may have come from.

I found this chunk of bone while excavating the pile of overburden where i originally found the contact end of a large shoulder blade. This sight has also yielded a vertebrae that i will post in the comments. I am, as usual, stumped at trying to identify what kind of bone this used to be. My mom says it reminders her of the wings of a pelvic bone. unfortunately there are not a lot of great pictures of the pelvic bones of large mammals on the internet. What do you all think?

Hello every one, does anyone can help me identifying this vert? It seems a thoracic vert, but I can't identify the animal, it was fished in the north sea so it's from pleistocene sediments. Maybe it's from a big cat? (that would be a Dream ahaha)
-
I found more parts of the, believed to be, cetacean vertebra. I found two of the coastal facets (i just call them wings) in the same sight, an so far im still having trouble finding and goo reference photos of vertebrae that have this feature, any ideas? [WinZip file deleted]

Thought this was a horse frag but after looking at other photos believe it may be a beaver molar??

Hi, just going through some rocks I brought back from Norfolk, UK, thinking quite a few may be fossils (I didn't have long so just grabbed anything I thought looked suspiciously organic by intuition) and as it turns out I think I was quite correct in a number of cases - I think I have quite a few pieces of whale and and a few little bits of mammoth tooth. Trying to confirm this to myself led to a lot of reading and learning online about the local geological formations involved and also whale anatomy, both new topics for me which I always enjoy delving into - part of the enjoyment of fossil hunting for me - I'm less of someone looking for beautiful specimens for display (though I'm not going to turn those down!) and more someone who loves the detective work of trying to identify obscure parts and recreate some aspect of the vanished world before us from its traces. And searching through whale anatomy and what these weird chunks could be I came across a picture of a whale periotic and realised that the weird little pot structure I had was almost definitely one of these, which if I am correct is good because I believe they are one part of a fragmented whale anatomy that is quite diagnostic. Also I then realised that a strangely hooked piece I found right next to it could well be the tympanic! The preservation here is unusual because many theorise that these kind of whale fossils were first laid down in sandstone in the Miocene when Norfolk was covered with a shallow warm sea, and then later in the Pliocene and early Pleistocene when temperatures dropped sea levels dropped too and the area became land (part of the reason the geology of this area is interesting is the constant transgression and regression of the sea over a few million years), these Miocene rocks were eroded away and the harder fossils reworked into new estuarine or nearshore sediments of this era, often but not always with a layer of hard iron-rich concretion coating them which helped protect them (I guess one question would be, is there anyway of easily removing this hard concretion layer?) So if I am right, these are bones from Miocene whales (many showing signs of shark damage), reburied in the Pliocene / Early Pleistocene and then finally eroded out again in the modern day - quite a journey! Anyway, enough background, for starters I'd love to see what people think about this periotic / tympanic. Am I right? Here's a summary of my findings (note I used a pic of dolphin periotic someone posted here for comparison so I hope that isn't too cheeky)

Hello everyone,I've recently acquired this piece of unprepped oreodont jaw section and want to do some prep work on it However I've realized that the jaw looks quite fragmented and is afraid that it might break apart into thousands of fragments. I had only prepped a knightia before and I am kinda confused what I should do now.

Hi everyone, I found this tooth over the summer in the White River formation of Wyoming. When I stumbled upon it, the tooth was already "exploded" into several pieces, so I glued it in place and dug around it, taking it out as a cemented chunk of dirt. At first I thought it was a young Archaeotherium canine, then I wasn't so sure and thought maybe Hyaenodon, I could be wrong and may not be predator at all as I know the rhinos, oreodonts and titanotheres all have canine teeth. A good amount of the crown is preserved along with several pieces of the root, however it is not complete and may be missing some vital pieces which could help us answer the question. the crown is around an inch and a half in length.

Hi all! Here's a tooth find from Monmouth, NJ. It's clearly a mammal of some kind, possibly cenozoic, but does anyone know what kind? Thanks!

Hi I found this on the beach at lake mcconaughy in Nebraska which means it could be Pleistocene or Miocene but most likely from the Ash Hollow formation. I’m pretty clueless when it comes to bones and could use some help figuring out what this is. Thanks! P.s. I did the flame test and it’s fully mineralized.
-
At first I thought it was the tip of a rib, but I see little swirls of enamel inside like a horse - though this doesn't look like the couple of horse teeth I've found. Perhaps another mammal of some kind? Myrtle Beach.

My dad collection of Indian artifacts Crystal's and all kinds of other things was passed to me when he passed. And there was this tooth I been tryin to find out what animal it belongs to and I was lead to this site. I know it's a molar and by what Google says it's a mammals. Can someone help me find what mammal it is?

I found this vertebra in Bartow county Florida along with some other mammal Pleistocene fossils. It was found in close proximity to some deer antler pieces and Mastodon incisor pieces. I found an almost identical vertebra online that said that it was a giant ground sloth vertebrae. The piece is heavily mineralized. Any opinions on this vertebra would be greatly appreciated. It has a diameter of 2 1/2 inches and a width of 1 1/2 inches.

Made a quick trip to the peace river today near Bartow today. Nothing too crazy but did find two things that I need some help on. My best guess on the first one is dolphin / whale tooth, but I haven't found many of them and the crown is kind of weird... maybe broken and then smoothed over by the river? The second is a very small fossil. I have found very similar ones before but never bothered to get them ID'd. My best guess is some kind of small mammal tooth. It is so small that I couldn't get a great picture with my iphone. The ends of the fossil (not pictured) are zig zagged, carrying on the patter from the sides (kind of like horse teeth). Definitely not ray dental plate like I originally thought. Any help is greatly appreciated! Thank you.

These pictures are one a fossil a work friend gave to me. He said he dug this up, on the opposite side of where I dig, twenty years ago when the plant first opened (I was 2 to 3). I'm thinking medium sized mammal, somewhere in the cloven hoof family. any ideas?

Found on the eastern shore of the bay.
