Hello, I found an oyster layer situated below a terrace overlooking the Colorado river in Travis county, Texas. I became curious about the ID after reading about the ostrea fossils found nearby. May be some more recent eastern oysters left over from others. There were plenty of these oysters embedded in reddish clay. Any help with this appreciated!

I think this is a piece of a crab, perhaps the ”torso”? I found a paper with crabs from Kristianstad basin, but only images of claws, and it is not part of a claw from what I can tell? https://sp.lyellcollection.org/content/434/1/241 The crab in the paper is named Protocallianassa. What do you think?

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!

I met up with my wife to celebrate Valentine’s weekend out east near Ft. Benning over the last few days. Finally, I got to take her out for an easy echinoid harvest at a place that was flooded on our last attempt or 2. This time she hit paydirt in the form of Upper Cretaceous Hardouinia bassleri echinoids. Kind of exotic for us, as cassiduloids aren’t too common in TX.

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.
