Fossildude19 Posted February 23, 2011 Share Posted February 23, 2011 (edited) Hello Andy1314. I'm not sure there's enough detail to be able to tell much of anything definitively.Looks like it could be a horn coral imprint or more worn brachiopod bits. It's really difficult to pin anything down with no information on where this was found, and the age of the formation it was found in. Sorry I can't be more helpful.

andy1314 Posted February 23, 2011 Author Share Posted February 23, 2011 they were found in lost pines texas in a dry creek bed, i've also found petrified wood, gastropods, lots of chert, some jasper, it's a very diverse creek bed as far as composition goes Link to comment Share on other sites More sharing options...
tracer Posted February 23, 2011 Share Posted February 23, 2011 not sure where you're hunting but seems more cretaceous than brachiopodaceous. just sayin'. Link to comment Share on other sites More sharing options...
TqB Posted February 23, 2011 Share Posted February 23, 2011 The little raised circular bits in the depressions look rather like casts of Cliona borings (ichnogenusEntobia) - which I think would be Cretaceous. Tarquin Link to comment Share on other sites More sharing options...
andy1314 Posted February 23, 2011 Author Share Posted February 23, 2011 my thinking is they were some kind of barnacle attatched to whatever animals made the imprints Link to comment Share on other sites More sharing options...
TqB Posted February 23, 2011 Share Posted February 23, 2011 Could be - is the rock flinty/cherty? - whatever they are they look like silica casts of hollows within the original shell material rather than on it - I could be seeing the photos wrong though.

MikeD Posted February 24, 2011 Share Posted February 24, 2011 The surface geology in that area is Eocene. I have seen similar rocks with fossils and imprints dumped in drainage ditches, on creek banks, etc. to prevent erosion. Some of them inevitably wind up downstream. They are probably imported from somewhere many miles west of there. I have a few similar ones. Still trying to determine their origin. Link to comment Share on other sites More sharing options...
