Syrian Posted August 19, 2018 Share Posted August 19, 2018 I joined the forum to get some help on IDing the fossils... They were found in the Blanco River area of eastern Kendall County, Texas. We find plenty of bi-valves and gastropods on a regular basis. Most everything we find is from the cretaceous period and makes sense given our ranch location. I've looked around for several months on the web trying to find something close to these below and can't seem to find anything. The graph paper is .5 CM squares so most of these are just over an inch long. I will let the experts give their opinions. Thanks for your interest!

DPS Ammonite Posted August 19, 2018 Share Posted August 19, 2018 They look like steinkerns (internal molds) of a highly curved clam (unknown). The marks on the inside of the curve look like impressions of a hinge area. Local experts should be able to give a more specific ID. @Uncle Siphuncle @erose @JohnJ To help us: any idea of what formation they are from? My goal is to leave no stone or fossil unturned.

JohnJ Posted August 19, 2018 Share Posted August 19, 2018 They look like rudist steinkerns. Search TFF and you will find very similar examples. The human mind has the ability to believe anything is true. - JJ Link to comment Share on other sites More sharing options...
caldigger Posted August 19, 2018 Share Posted August 19, 2018 I can't answer your ID question, but I know an auction site that you can pass them off as dinosaur claws on. Link to comment Share on other sites More sharing options...
Uncle Siphuncle Posted August 19, 2018 Share Posted August 19, 2018 I’d start with rudist steinkern as well. Grüße, Daniel A. Wöhr aus Südtexas "To the motivated go the spoils." Link to comment Share on other sites More sharing options...

ynot Posted August 19, 2018 Share Posted August 19, 2018 Look like steinkerns of some type to Me. Sorry no jokes on this one (from Me at least). Darwin said: " Man sprang from monkeys."

BobWill Posted August 19, 2018 Share Posted August 19, 2018 Since I have little experience with rudists (or curved clams or claws or skulls:) my 1st thought would be very worn whorl sections of ammonites but they would have to be fairly evolute and from the body chamber unless they were some of the rare phragmocone pieces without septa or suture showing. Is that too vague? lol Link to comment Share on other sites More sharing options...
FranzBernhard Posted August 19, 2018 Share Posted August 19, 2018 My first thought was also rudist steinkerns, but what puzzles me is, that all have nearly the same curvature. No, wrong, not all have the same curvature... Btw, the small squares are 1 mm large? Then most specimens are a little bit over 1 cm lage, about 1/2 inch.

Syrian Posted August 20, 2018 Author Share Posted August 20, 2018 Thanks for the help, I think they look like at least half of a rudist steinkern. Help...how do I close my thread? Link to comment Share on other sites More sharing options...
DPS Ammonite Posted August 20, 2018 Share Posted August 20, 2018 You do not close your thread. It remains open unless an administrator or moderator finds a problem and: hides it; locks it to further replies; or deletes the whole thing. My goal is to leave no stone or fossil unturned.

Miocene_Mason Posted August 20, 2018 Share Posted August 20, 2018 Leaving it open allows future people to learn from the thread, in this way the forum becomes a sort of open encyclopedia that stores information for those in the future, while continuously creating new content. “...whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been and are being evolved.” ~ Charles Darwin Happy hunting, Mason Link to comment Share on other sites More sharing options...
