Echies and Ammonites of Texas (Georgetown Formation)
JamieLynn posted a topic in Fossil Hunting Trips
I made a "concentrated" study of the Georgetown formation -about an hour north of me (I usually hunt in the Glen Rose and Walnut of Texas) so it was fun to hit up four spots to see what different species I could find. I was happy to gather a good variety of specimens, including a couple of "best" specimens of common Texas finds - a lovely BIG Neithia scallop with both the top and bottom valve intact, a nice Ostrea carinata and lots of well preserved turritells, including the tiniest I've ever found. But the fun stuff is the Echinoids and the Ammonites! For the Echinoids: I FINALLY found a Salenia Mexicana (that didn't crumble in my hands like the LAST one I found) even if it is a bit water worn. I'm still happy with it. Plus an excellently preserved Heteraster obliquatus and a nice Phymosoma which is still encased in a bit of matrix, but that's okay. But my find of the day was the Tetragramma taffi (i'm pretty sure on that ID, let me know if I"m wrong!) Even thought it's quite squished and has a lot of matrix, it's still my first one, so I"m stoked!! The "other" fossils: A pyrite shell, not great, but cool because it's pyrite The Echinoids! Phymosoma Salenia mexicana: Tetragramma taffi a nice Heteraster:- 9 replies

I was gonna call this a monthly round up but I just realized it's been four months, adjusting to new job has had me messed up. I've only gone to 2 locales in 4 months and I'm having withdrawals. Anyway, I stopped at a outcrop of buda formation for about 30 minutes while the family went shopping, the buda had given me 2 graptocarcinus carapaces previously so I was looking specifically for that, I found what I thought was a carapace but it turned out to be a chela with just a nub of a dactyl, unfortunately the finger got broken off somewhere in between getting it out of the ground and getting it home. I assume this is graptocarcinus but I have not found any pictures of the chela.
