RobertBlackBeard Posted May 25, 2016 Share Posted May 25, 2016 Now this I did not find in the creek that my other findings were found in. In fact I didn't find this one at all, it was given to my father when he was seven years old in 1959. My father told me that a friend of his father found it while working on a construction project somewhere between the Oklahoma and Texas border. Unfortunately my grandfathers friend that found it decided to hammer a nail in the middle of the darn thing so he could hang it on a tree. But other than that it looks relatively unharmed. I just want to know what creature use to call this thing home, if that is even possible to know from just looking at these pictures. Link to comment Share on other sites More sharing options...
Troodon Posted May 25, 2016 Share Posted May 25, 2016 Nice ammonite, I'm sure those familiar with the locality can give you a species. Link to comment Share on other sites More sharing options...
sixgill pete Posted May 25, 2016 Share Posted May 25, 2016 You have an ammonite there. I do not know the exact species, but it is a very nice looking one. 1 Bulldozers and dirt Bulldozers and dirt behind the trailer, my desert Them red clay piles are heaven on earth I get my rocks off, bulldozers and dirt Patterson Hood; Drive-By Truckers May 2016 May 2012 Aug 2013, May 2016, Apr 2020 Oct 2022 Link to comment Share on other sites More sharing options...
Fossildude19 Posted May 25, 2016 Share Posted May 25, 2016 This looks like a Cretaceous age ammonite - possibly Mortoniceras sp. Wait for some local experts to weigh in, before attaching a label to this. Very nice one, too.

DPS Ammonite Posted May 25, 2016 Share Posted May 25, 2016 It is probably from the Duck Creek or Fort Worth Formations which are present near Lake Texoma and the Red River. My goal is to leave no stone or fossil unturned. See my Arizona Paleontology Guide link The best single resource for Arizona paleontology anywhere.

Manticocerasman Posted May 25, 2016 Share Posted May 25, 2016 this should give you an idea on how an ammonite should have looked like : growing old is mandatory but growing up is optional. Link to comment Share on other sites More sharing options...
RobertBlackBeard Posted May 25, 2016 Author Share Posted May 25, 2016 this should give you an idea on how an ammonite should have looked like : Wow freaky. Are ammonites related to octopuses and squids? Link to comment Share on other sites More sharing options...
Manticocerasman Posted May 25, 2016 Share Posted May 25, 2016 (edited) Yes they are cephalopods. Nautiluses are simmilar creatures that still live today, but they are a different group than the ammonites. Ammonites and Nautiluses have both shells that are divided in chambers, those chambers are connected to the last ( where the animal lives) with a sifo ( a tube) They are able to fil the chambers with either gas or water. So the shells kinds of works like a submarine. The 2 main differences between Ammonites and Nautiluses is the complexity of the walls dividing the chambers ( a very complex fern like pattern on the ammonites and a simple curve for Nautiluses. ) The second difference is the position of the sifo. For a nautilus the sifo is in the central position of the wall, with ammonites the sifo is in ventral position. You will find plenty of information on the internet about this subject.

Guguita2104 Posted May 25, 2016 Share Posted May 25, 2016 I agree with Mortoniceras sp. If I'm not wrong (please, feel free to correct me) they are quite common in Texas's Cretaceous. Regards, Link to comment Share on other sites More sharing options...
fifbrindacier Posted May 29, 2016 Share Posted May 29, 2016 (edited) It's a nice gift your faher had, and quite well preserved despite the hole for the nail.
