OwlEyes Posted January 6, 2019 Share Posted January 6, 2019 I found these fossil in Texas and not sure what they are or which species they belong too. Please help me identify them. Thanks. 1. I found this in Kiamichi formation in Fort Worth, Texas. I think it is fragment of turtle shells but I am not sure. 2. also on Kiamichi formation, Fort Worth, Texas, I found this ammonite, please let me know which species it belong too. Thanks. 3. and the echinoid is also at the same place. Which species is it? 4. I also found this at Duck Creek Formation in Fort Worth Texas which I don't know what it is Thank you.

fifbrindacier Posted January 6, 2019 Share Posted January 6, 2019 Hi, the last ones might be burrows infilleds. Duck Creek is cretaceous.

Tidgy's Dad Posted January 6, 2019 Share Posted January 6, 2019 1. Some sort of concretion. 2. Mortoniceras. 3. Epiaster whitei. 4. Infilled burrows. 2 Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...

fifbrindacier Posted January 6, 2019 Share Posted January 6, 2019 For the urchin i propose macraster. And your shark tooth is too worn, but maybe @Al Dente or @Harry Pristis will chime in. Could you also give the size of your items ? The american dollar doesn't "speak" to me. 1 "On ne voit bien que par le coeur, l'essentiel est invisible pour les yeux."

SailingAlongToo Posted January 6, 2019 Share Posted January 6, 2019 Shark tooth looks like a Hemipristis serra (snaggle tooth shark) Don't know much about history Don't know much biology Don't know much about science books.........

Maybe a kind of oyster ? 2 "On ne voit bien que par le coeur, l'essentiel est invisible pour les yeux."

JohnJ Posted January 7, 2019 Share Posted January 7, 2019 Number one is likely the internal cast of the bivalve, Cyprimeria. This one looks like a partial infilling of the shell on one side. 4 The human mind has the ability to believe anything is true. - JJ Link to comment Share on other sites More sharing options...
BobWill Posted January 7, 2019 Share Posted January 7, 2019 I disagre on the ammonite. There are two Morts in the Kiamichi but yours is not either one. it's one of the 10 species of Oyytropidoceras found there. 3 Link to comment Share on other sites More sharing options...
-AnThOnY- Posted January 7, 2019 Share Posted January 7, 2019 Without a doubt, the ammonite is Oxytropidceras. Very nice! 1 Link to comment Share on other sites More sharing options...
KimTexan Posted January 7, 2019 Share Posted January 7, 2019 Yes the first is s bivalve. The ammonite is an Oxytropidoceras, a nice one at that. Mortoniceras have straight ribs and tubercles. The ribs on Oxys are curved and they don’t have tubercles. The long skinny things. The first looks like a Thalassinoide burrow fragment, but could be lobster if you can see fine bumps. (Not a lobster. I was looking at the little bumps on top middle, which is a piece of urchin as Dan pointed out below. I think they’re all Thalassinode burrows.) Sometimes the bumps run as a single line down the side. I have not found lobster in the Duck Creek, but I have found them in the Paw Paw, which is still part of the Washita group. There is overlap within the formations of the Washita group. The echinoids, I am not good at echinoid ID. @erose is and I thought @JohnJ was too. If I need to I can pull out my books, but let’s see if anyone I tag can help us with that. I thought @-AnThOnY- knew his echinoids. I know @Uncle Siphuncle does. 1 Link to comment Share on other sites More sharing options...

I don't think I'm seeing any lobster appendages, but rather burrows, one with a fragment from the underside of a spatangoid on it. Not knowing locality, Hemiaster whitei is a good guess on the ech, which tends to be found in many of the same intervals as Oxys, or at least close by. 3 Grüße, Daniel A.

There is a piece of shell or carapace there still in place. Or do you think it is ancillary, and random? Link to comment Share on other sites More sharing options...

The gross form lines up more with burrow as well, as the burrow is more amorphous than a lobster's body or appendages. Nature tries to trick our eyes at times. 3 Grüße, Daniel A.

Ok I can believe that it’s part of an urchin stuck to it. The lobster legs I have are straight and have a line of bumps running up the side.

Good eye seeing the ech frag in that middle one. Agreed Link to comment Share on other sites More sharing options...
