Rockwood Posted September 10, 2021 Share Posted September 10, 2021 Looks just a tad too complex not to be something, but, quite enough to be something ? Link to comment Share on other sites More sharing options...

val horn Posted September 10, 2021 Share Posted September 10, 2021 The first of the last photos looks like apiece of rock with several poorly preserved shells or shell impressions If it were mine i would put it in a box with a label. But i would also contact the dallas paleontology society and go on a field trip with them or go to mineral wells fossil park. Texas has so many spectacular fossil sites that i would want well preserved fossils and friends to collect with.—-val Link to comment Share on other sites More sharing options...
Rockwood Posted September 10, 2021 Share Posted September 10, 2021 There you go. I'm pretty sure this is crinoidal limestone. The texture in the first one may represent an accumulation of tiny pinnules. A certain percentage of it may be oolitic in nature. Link to comment Share on other sites More sharing options...

erose Posted September 10, 2021 Share Posted September 10, 2021 IMHO I see weathered limestone. Here in central Texas limestone of many many textures makes up the majority of the geology. But “central” Texas is still a big place so knowing where it was found would help us know what kind of rock it really is. also in my humble opinion it is not crinoidal limestone.

tombk Posted September 10, 2021 Share Posted September 10, 2021 Well, I started out thinking rock only. Then I put on my reading glasses and zoomed in. I do see @Rockwood's point about the texture in some of the photos. There is no one part that I can point to and say "There's a fossil," but some of the patterning reminds me of a compact conglomeration of tiny crinoid fragments that I've had sitting in my office. It's possible that there's some of this going on in some portions of some of the rocks in this post. I agree with @val horn that going out on some fossil hunts with other folks and to sites where there are known to be well-preserved fossils will be exciting. I, too, started out posting pictures of rocks that seemed a bit too complex in texture and shape to be merely geological. Some were and some weren't, and some we couldn't tell. But it's one thing to have a specimen that's mostly a rock with possibly some poorly preserved fragments of fossils in it and something quite different to find a bona fide, incontrovertible fossil. Happy hunting Link to comment Share on other sites More sharing options...
abyssunder Posted September 10, 2021 Share Posted September 10, 2021 I'm not sure what I'm seeing, so the rudist remains in matrix will be just a hypothesis.

Rockwood Posted September 10, 2021 Share Posted September 10, 2021 Perhaps the bigger hammer theory should be applied here ? Just to separate more particles for study under magnification. Link to comment Share on other sites More sharing options...
