Is this spatula-shaped item a fossil? Perhaps a coral or bryozoan? From a Cretaceous fossil cliff on the coast of Portugal. Matrix is limestone. Item apparently has two elements, 1) a flattened, darker "blade" that widens from end to the other, and 2) a lighter, roughly cylindrical element that runs down the middle. A mold of this cylindrical element seems to extend beyond where it ends.

As a child, I collected a lot of "fossils". Whether it was from a campsite, a park, a playground, or my own yard, I would pick up rocks and declare them to be fossils. I still have several of the rocks I collected laying around. Most of them, as you would guess, are just oddly shaped rocks. But miniature me may have occasionally picked out things of genuine value. So I'm going to dump a few in this thread and see if I really have anything worth keeping. Note that while I can't remember where I found these all those years ago, they're most likely from within 2 hours of Tulsa, Oklahoma, since that's where I've lived my whole life. Though there's also a chance that a few are from Mexia, Texas. First up is probably the most interesting looking. Looks like it came from a stream or lake, based on erosion. Second up: Third: Fourth: Fifth and final, also has a lot of stream erosion: Tell me your thoughts.

Hello together, I got this one as a gift, all the info I have is "rock with a nice pattern from the Sahara desert ". I am relatively sure its not a fossil, even more so after looking at the macro-fotos. Still it reminded me of tentaculites, and I wonder if there are fossils disguised by desert varnish, or if it is all pure geology. What do you think? Scale is metric, as you can tell by the ten/five small marks to a big one. Best regards, J
