Found in Ram. Looks mammalian, possibly beaver? Throwing me off because it doesn't seem modern. Any thoughts?

This was found in northern Florida. I thought it was a claw core, as it is definitely not a tooth. However, now I am thinking antler tine. I would love some opinions on if that's correct!

Hi guys! I am new to the forum but am an avid 23 year old fossil hunter and artifact collector. I have been hunting for a good while now and have a large collection from all over Florida. I was recently doing an overnight camping paddle on the peace river to hunt now that the water is low, and I found many things (including some worked flint among the fossils, which was quite surprising) but this particular find I need some opinions on! I’m not convinced that it’s entirely fossilized, though what is confusing me is that it is much heavier than it should be and also did not react significantly to the burn test when compared with modern bone. It is similar to a coyote except in the hinge of the mandible area. I found this under a gravel deposit in a particularly limestone-y area of the river. I have other fossil jaws in my collection which are similar in weight, but not so much color. Any opinions would be appreciated!

I found this radius a while back in the Brazos river in SE Texas. This piece is about 6.5 inch long. It looks much like cat radii I see online but I'm looking for other thoughts. @Shellseeker @Lorne Ledger @Harry Pristis @garyc

Got up early, went out hunting to a favorite location with good friends. I had searched this spot so often that I went in believing that I would have to prospect new locations before today was over. Turned out not to be true. After 5-10 small shark teeth in each of the 1st 2 sieves, this interesting fossil fell into my lap. It is 6.5 inches long and 2.75 inches at its widest point. Going to be a great day. I will make some observations. 1) At 2.75 inches wide, it is far smaller than the width of an adult tooth and must be from a juvenile. 2) It consists of approximately 3 plates. A complete juvenile tooth might be 10-12+ plates 3) The section I have found has not been chewed upon YET.. It was likely un_erupted when the juvenile died. 4) Maybe redundant to #3, the section I have found is 100% enamel, 0% roots/dentin/cementum Questions: When one of my friends looked at the fossil, he said that I had found the "posterior" end of the tooth, because the "fingers" you see, are only present in this volume on the posterior end. News to me, for Mammoth tooth experts, is it true? Here is a very interesting link https://www.fossilera.com/pages/about-mammoth-molars which includes this discussion: So, if there are 2 set of deciduous teeth between Age 3 and Age 20, let's speculate that each set lasts more or less 8 years... My find was being created as a "deciduous" tooth, and creation of a deciduous tooth happens around 4 years of age and 12 years of age. My gut feeling looking at a lot of deciduous mammoth teeth, many medium in size and many larger in size is that my find is one of the larger "juvenile teeth" created at Age 12. All comments appreciated, especially from someone who knows about sizes of deciduous mammoth teeth. p.s. I did take some comfort in seeing scientific papers that estimated modern elephant age based on tooth size... and the comments that it should also apply to Mammoths.

Greetings from Venice, FL. After viewing a recent post, I am interested if anyone can identify my recovery from Pleistocene material. I believe it is the distal end of a humerus. It was crushed by a tractor. Photo A shows the distal end. The dimensions on Photo A is 5cm wide. Height is 4cm. Photo B is anterior view. It would be great if anyone could identify what animal it may have come from. Thanks in advance. -Michael

This is about the most complete vert that I’ve found. I’m horrible at identifying vertebrae, but I’m going to stick my neck out (pun intended) and suggest that this is a bison cervical vert. Found on the Brazos River in SE Texas

Hello everyone, can you help me identifying this mandible fragment, I'm unsure of what it can be, maybe Raccoon or a mustelid. I'm sure some Florida expert can determine much better than me what this can be

This was found close to Charleston, SC. Any ideas on what it might be from? It looks mammal to me.

Went hunting with my Son. That in itself made it a great day. We have grown closer as we age and the separation over the last year has only made our time together more enjoyable. For most of the day, we had the numerous and excellent finds that the Peace River hunts famous. Things picked up in the last hour. Large Tooth: Clearly an upper, could be M1, or M2 or M3. The table below has measurements for a M1 and M2, but not M3. This find 35.1 mm, 22.6 mm, and 67.1 mm respectively, so I thought "maybe" the M2. I also found this photo on the Internet: That tells me that this is the "left" maxilla, and just looking at the "shape" pattern (above and below photos), it is either M2 or M3. So, I am looking for error in my thinking. and most of all I am looking for TFF Bison experts to tell me whether it is a M2 or a M3 and why.... so I'll go after the usual Bison expertise suspects. @Harry Pristis @Brett Breakin' Rocks @garyc @digit @Thomas.Dodson Please add others you think of , Jack

Greetings from Inland Venice, FL. Pleistocene material. This is an unusual fossil find for me. It measures 6 inches long by 3 inches wide. It is 3.8 inches in height. Two different sides are flat. Photo A: overall image. Multiple images show worn black fossils embedded in relatively smoothed, compacted silica. This item was recovered from sand/clay, calcium carbonate material in hole approx. 10 feet deep. There were no other specimens with this type of composition recovered. FYI: Indian artifacts confirmed to 10,000 B.C. recovered within 10 miles. I have not previously recovered any Indian artifacts. I do not think this would be an implement/ancient tool. I'm looking for feedback. Thanks in advance friends.

Greetings from Inland Venice, FL. Unusual fossil find for me. Pleistocene material. My first thought was Dugong when I picked it up, and fit great into my hand. I have found hundreds of Dugong ribs in the last year at my location. This is an unusual one due to the smooth texture. It measures 4.5 inches long by 2 inches wide. Density is 2.51 g/cm3 if you are interested. Photo labeled "4" shows odd texture. Closeup attached. FYI: Indian artifacts confirmed to 10,000 B.C. recovered within 10 miles. I have not previously recovered any Indian artifacts. I'm looking for feedback. Thanks in advance friends. -Michael

Supersized Tilly Bone? Looks like a Large Gummy Bear. Do you agree on the fossil? Not dense at all. Looks like a sample I have collected already...but this one is very large. 7 cm long, 4.2 cm wide This is a good reference piece. -Michael

Florida Gastropod Identification Help - 2 Different Fossils
Gregory Kruse posted a topic in Fossil ID
Hello everyone, I found these gastropods along the Sanibel Causeway in Ft. Myers, 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 this fossil? Thank you!

I think this is part of a temporal bone. It's approximately 2 x 2 x 2 inches. Not expecting a taxonomic identification, I'm just hoping someone can recognize and point out a couple osteological landmarks for me so I can orient myself with respect to adjacent cranial bones and know if I should be comparing it at the left or right side of the skull as I look for a match.

Can anyone help me with the following fossils? (what species etc.). Made a selection of a bigger compilation (most important fossils are shown). Kind regards

Can anyone help me to determine the fossils on the pictures? They are all found were bone fragments from Pleistocene and/or Holocene material has been found. Could the teeth belong to Bos primigenius (Bojanus, 1827)? I think they belong to the above mentioned art. I also found some horse teeth at some locations. The brownish coloured teeth are from Zeeland. The black teeth are from Limburg (found in water/creeks). They are black and/or brown and fossil (not recent material judging by the colour and erosion).

Found in South Texas Next to white mastodon tooth with white tusk. The stuff down here does not mineralize. This is misc stuff I thought was chunkothere, but looked a second time and saw something there. first 3 I was wondering if its turtle or tortoise shell.

Found this in South Texas sandy gravel matrix. Pleistocene era. It's pretty small. But could this be a glyptodont osteoderm? It doesn't look like the turtle/tortoise pieces I normally find. The seams are very pronounced, and the grain on broken places is very fine and not as spongy as the turtle pieces.

So I was looking at some cave bear jaws for sale and saw that the same website also offers brown bear jaws(fossils). Which makes me wonder if the cave bear jaws turn out to be from an extant species,will I get in trouble? As many of you may know, pleistocene fossils contain both extinct (cave lion, mammoth, etc. ) and extant (jaguar, bear, tapir etc.) Does anyone have any experience regarding this?
