Fishkeeper Posted January 23, 2017 Share Posted January 23, 2017 ( the weird succulent plants under it are Lithops, I wanted natural light and they were in the window) Found this along the San Gabriel river near Georgetown, TX. It was in with some small chunks of shale that had broken off the main formation. Pretty sure it's a sand dollar, and I know it's probably not possible to tell exactly what kind, so what I want to know is this: does finding this mean that I should go back and look again? This was the only fossil I found in the area, but it could have been I just didn't know what to look for. And I know there are some fossils that, if you're finding them, tell you "hey, this is a good area for X, Y, and Z because they require the same conditions to show up", but I'm not sure what those fossils are. I find oysters and occasional snails upstream in the loose river rock, if that helps at all. Though, really, there's nowhere in Texas I've seen that doesn't have fossilized oysters and occasional snails. And would anyone happen to have any links to what marine fossils look like embedded in shale, so I can start dialing my eyes in? Link to comment Share on other sites More sharing options...

Fishkeeper Posted January 23, 2017 Author Share Posted January 23, 2017 Ah, cool, thank you. The ridges looked a bit deep for a sand dollar, but evidently I'd forgotten that scallops exist when I was trying to ID it. Does the scallop give any clues as to what else I should be looking for in that patch of shale? Rounded shells? Long, thin shells? Segmented exoskeletons?

According to this website, the area near the San Gabriel river is Cretaceous in age - ichnofossils,vertebrates-reptilia-dinosauria(tracks) are known from there. Hope that helps.
