Chomper Posted February 22, 2018 Share Posted February 22, 2018 I found this over the summer at stratford hall in VA. Can anyone help me identify this? Thank you! Link to comment Share on other sites More sharing options...
indominus rex Posted February 22, 2018 Share Posted February 22, 2018 Could it be a sponge or a coral? I will leave this one to the experts. Life started in the ocean. And so did my interest in fossils. Link to comment Share on other sites More sharing options...
Tidgy's Dad Posted February 22, 2018 Share Posted February 22, 2018 It is a piece of chert or flint which does have bits of fossil impressions in it. Possibly sponge impressions, yes. Like this, but often the sponge body erodes away leaving just a mold. Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...
abyssunder Posted February 22, 2018 Share Posted February 22, 2018 Maybe imprints left in a pebble by gastropods.

Kane Posted February 22, 2018 Share Posted February 22, 2018 I'm in agreement with the others. I also see a kind of Hormotoma sp like gastropod imprint there. Good quality images, by the way! ...How to Philosophize with a Hammer Link to comment Share on other sites More sharing options...
Chomper Posted February 22, 2018 Author Share Posted February 22, 2018 I licked it and my tongue stuck. The lick test says bone. I'm off to mouthwash. Link to comment Share on other sites More sharing options...

Many rocks will also stick, depends on the porosity of the rock. Darwin said: " Man sprang from monkeys." Will Rogers said: " Some of them didn't spring far enough."

Rockwood Posted February 22, 2018 Share Posted February 22, 2018 Just to fill anyone not familiar with the situation in a bit. The spot is in an area where deposits are of Neogene age and Fenestrates went extinct in the early Triassic I think. It almost had to have rolled in the current of the Potomac River from some upstream source. Link to comment Share on other sites More sharing options...
GeschWhat Posted February 23, 2018 Share Posted February 23, 2018 It sticks, really? Chert does not stick. It is possible that it is a coprolite. It could have come to rest on the sea floor (hence the gastropod imprints), and those boring clams do seem to like the calcium phosphate. @Carl Lori www.areallycrappystory.com/fossils www.facebook.com/fossilpoo Link to comment Share on other sites More sharing options...

Al Dente Posted February 23, 2018 Share Posted February 23, 2018 I don’t think it was a fenestrate bryozoan. Probably an encrusting bryozoan on a gastropod that left an impression. Link to comment Share on other sites More sharing options...

It could just as easily be a weathered pebble with invertebrate molds and/or burrows. Link to comment Share on other sites More sharing options...

Like Carl said, the lick test is not definitive. Not all coprolite/bone sticks. Of course I don't usually go around licking random rocks - just those I think might be coprolite or bone. So I haven't actually encountered a rock that sticks that has not been one of the two. Here is a recent beauty I picked up at the Tucson Gem Show. It was found in South Carolina. It does not have any cool impressions, but it is riddled with clam borings. The only reason I know for sure mine is a coprolite is the button-like sphincter mark on the end. And yes, it does have good stickage as well. As you can see yours is similar. I am an optimist, so I would label yours as a "possible" coprolite.
