This is a Topic dedicated to DIGITAL FOSSIL PREPARATION. It is intended to be a repository for all topics concerning digital fossil preparation. Technology has come a long way, and now, more frequently, is being used as a means of Fossil Preparation. Getting a digitized scan of a fossil still in the matrix can be a game changing use of technology. Please post any relevant links to previously posted topics concerning CAT Scans, X-rays, or Digital modelling/3D printing.

Notice the ridge inside each alveolus, see n in the first photo just above that sand grain stuck in there. That is what tells me this is rabbit, not rodent. That is typical shape of rabbit lower molars.

It takes a bit of technical ability, but if you're up to testing its specific gravity that should do it.

I would be more inclined to call these nano teeth. They have a nano look to me at the base. More likely tyrannosaurid is appropriate though especially without having a county associated with it unless someone can confirm nano.

I think modern too. Many of the seeds from members of the family Fabaceae are extremely hard.

That is probably true. There's like 6 or 7 Ptychodus species known from the Kamp Ranch. You'd think there has to be some sort of niche partitioning at play if that is for sure the case (unless there are other weird things such as sexual dimorphisms being counted as diff species etc.). I haven't gotten to read their reasoning for why they assigned these to Ptychodus sp. (and there's multiple specimens so maybe multiple species?). Just from that pic of the partially exposed tooth and the age of the fm, it kinda looks like P. marginalis or maybe P. decurrens. Both of those are low crowned species and if any taxon of Ptychodus was eating benthic organisms, I for sure would've thought it was one of those. Now I'm even more curious as to what oddballs like P. whipplei were doing! Also, I just noticed Aquilolamna (?Cretomanta) in the background of the art. I hadn't made the connection that that amazing specimen came from the same quarry. They must have a lot of amazing sharks waiting to be published...

Brevicollis started following Teeth from a theropod, hell creek
-
Hello, I saw these teeth for sale today and they were listed as "T-Rex". And because theyre so cheap compared to T-Rex teeth, I wondered if they really are, and if they turn out as Rex, I think on buying one. The teeth are just about 1 cm in length, so quite small for a Rex. Must have been a very young individual, or a Nanotyrannus instead. Sadly there were no centrated pictures from the bottom cross section that could help identifying them. And sadly, the exact finding location and county wasnt named, it was just "Hell Creek". But there were plenty of Tyrannosaurs found in this formation. So I doubt its still identifyable. But any help and ideas are appreciated !

it is cold to the touch, it bounces on a tile floor, I am sure it is rock but the level of detail confuses me. I don't want to scratch it or anything I don't know how to test it.

Peace River 4/24/2024 (lots of 4s)
Shellseeker replied to Shellseeker's topic in Fossil Hunting Trips
Thanks Jp, Exactly !!! In January 2018, I found the ONLY fossil I ever found of Platygonus bicalcaratus in a feeder creek to the Peace River.. Absolutely great to have a comparison tooth. Now, after 6 years I hope for a 2nd one.. Take a look at the "left" m3.. I think mine is the right side m3. I was incorrect on the tooth position. A premolar is just too small for my 23 mm tooth. I looked at a couple of nice peccary premolars that @PrehistoricFlorida had on his website.. I have sent an email to Richard Hulbert.- 6 replies

Some people have great imaginations. I thought I was one. But I see absolutely NOTHING in that rock that resembles a bird or anything else for that matter, no matter how long i stare at it. Not a slam to the OP - more of a kudos for a great imagination

I’ll say it so it’s out of the way. I don’t honestly know but might as well eliminate hogs. Sus Scufa m2? Now, why does your tooth have that cool ridge around the base? I don’t see that on hogs teeth. Jp

Piece of what I believe is reptile rib bone from Big Brook, NJ. Bone fibers are very dense - any chance it could be dinosaur?
Carl replied to TRexEliot's topic in Fossil ID
I wouldn't go past IDing this is merely a bone fragment, likely reptile. -
