These look like mollusks that are missing half of the shell exposing the creature itself. 2 different specimens. I found them on the Nueces River in Southwest Texas

Do these go together? Associated pieces?
Still_human posted a topic in Is It Real? How to Recognize Fossil Fabrications
I can’t figure out if these are 2 associated jaw pieces. In most pictures they sure look it, but some pictures make me second guess it, and if they aren’t, they’re definitely still the attaching pieces, even if from different animals. I was looking at it backwards for awhile, which set me back, but I figured out the thicker part is actually the front of the jaw, right before the curve, or right after it starts, if it’s been glued on at the incorrect angle, which I think could also be possible. the 1st picture looks very strange because of how that smaller section suddenly drops down and gets taller, and especially strange after researching and finding out that it’s supposed to get wider there, but actually SHORTER. the 2nd picture looks good, except it MIGHT supposed to start slightly curving inward at the point of reattachment pics 1,3,4,6,&7 all make it look like they rent supposed to be associated together, but the other pics make it look very accurate. I don’t know what to think, so I thought I’d see what people with much better knowledge than I, think about it.

From the album: Marine reptiles and mammals
Basilosaur(us?) frontal lower jaw seyction, from Boujdour, in Morocco. Hopefully the species can be distinguished with some more info -
From the album: Marine reptiles and mammals
Almost the entire frontal canine portion of the lower jaw of a Basilosaur. As you can see, the area where the absent front canines were, at the tip of the piece is visible, as well as where the missing last canines were situated. Although it was labeled as a Basilosaurus, I’m a little hesitant to consider that the case until I can personally corroborate the information. Apparently from Boujdour, I’m just having trouble finding information about which whales are, or are not found there, so until then I’ll leave it more open with just Basilosaur. -
Hey guys. I picked this tooth up recently and have delved into the world of Meg teeth. I’ve been trying to identify the position of this tooth. I am having great trouble finding a way to properly identify lower vs upper teeth. I read some things that say it’s all in the root, V shaped is lower and U shaped is upper. Other things I’ve read are no it’s all in the curve of the tooth, uppers curve outwards while lowers curve inwards. So can someone help me out and teach me how to spot the differences and properly identify these teeth? And any idea on my tooth’s position? I had it as an upper A2 initially but now I’m not so sure. It measures 6-1/16” on the slant. Thanks y’all!

From the album: Marine reptiles and mammals
Unidentified Cretaceous crocodile species, suggested by multiple people, to appear to be a Dyrosaurus, came from the second phosphatic layer of a phosphate mine(what a shocker!)around the suburbs of Khouribga, Morocco. Original teeth, not replacements. Have gone through and cleaned up the base of some of the ones that had some sand around them. -

Cross sections of the stomach, full of squid/cephalopod hooks and beaks, of an early Jurassic ichthyosaur (Stenopterygius quadriscissus). One slice has the animals ribs, the lighter tan objects, around the stomach, while the other is entirely of the stomach contents. -

Here's a treat for the troops. These have been hidden from public and scientific view since they were acquired from the finder. I purchased them from a civil war relic hunter and collector, who claimed to have these found together, but he wouldn't divulge exactly where. I suspect coastal Charleston, north to possibly southern NC, based upon his distance of travel from the sale, which was the old Civil War Museum, located in downtown Myrtle Beach - Mid 90's.(A friend who worked there, alerted me of the seller's presence.) The owner also collected fossils and displayed these, so it was known as a place of trade and sale for both artifacts and fossils. When I first saw them, I immediately recognized the possibility that they were a pair, and likely land finds, but what I didn't expect to discover, was their curious potential axial relationship. Published relative axial ratios of known or suspected associated sets reveal similar math to what I've found in these Both appear to be from the same side of the jaw, which makes a reasonable argument for how they may have literally, come together in the first place. I've managed to contact one nationally recognized expert who seems intrigued. Unfortunately, there's probably no DNA remaining, but if you've ever watched Forensic Files on TV, more than just DNA is often used to establish beyond a reasonable doubt. I think this is also a good time for a poll, recognizing of course that you can't see these in person.

Just wanted to share a new fossil I bought some days ago. It's the right side of a mandible from a cave bear (Ursus spelaeus). It's about 40,000 years old, 30 cm (12 in.) long, and was found in Romania. I find ice age mammals really interesting, so I'm happy I got this!
