PetrifiedDoubleGulp Posted February 23, 2017 Share Posted February 23, 2017 Yesterday I looked in my batch of unattended rocks and found one very mixed fossiliferous rock I had been meaning to explore. These are two of the specimens I found inside: Link to comment Share on other sites More sharing options...
Fossildude19 Posted February 23, 2017 Share Posted February 23, 2017 A few different views might help determine what these are. The small one looks a bit like a bivalve, but the other one I've got nothing.

GeschWhat Posted February 23, 2017 Share Posted February 23, 2017 At first glance, I'm not seeing coprolites either. Like Tim said, closeups/different views might help. Where were these found?

doushantuo Posted February 23, 2017 Share Posted February 23, 2017 let me perfunctorily chime in with the above: i don't see the characteristic morphology of coprolites as known thus far to all known experts. Link to comment Share on other sites More sharing options...

EMP Posted February 23, 2017 Share Posted February 23, 2017 Knowing the age of the rocks would be a great help for identifying specimens like these. Here's a picture of a fossil seed surrounded by other plant parts (I previously thought of as an arachnid) from a Triphyllopteris seed fern from the lower Mississippian for comparison: There are some similarities with your second specimen, but something just seems off about it. Particularly the shape and striations which are more indicative of a bivalve to me. Link to comment Share on other sites More sharing options...
PetrifiedDoubleGulp Posted February 23, 2017 Author Share Posted February 23, 2017 This clump was from Shoal Creek which has some Pleistocene and Upper Cretaceous if Im reading my geological survey right. Thanks!! Link to comment Share on other sites More sharing options...
Peat Burns Posted February 23, 2017 Share Posted February 23, 2017 If it is a seed / plant diaspore, and if it is late Cretaceous, one taxon that you might compare it to is Spinifructus antiquus. I am not sure if it has been found outside of the Lance and Hell Creek Formations, but it does have longitudinal striations. It has sort of a "pear shape". Can't tell the original shape of yours due to condition and angle. Might be a related taxon. Just a thought. Link to comment Share on other sites More sharing options...
JohnJ Posted February 23, 2017 Share Posted February 23, 2017 No mystery here. These are both bivalve fossils (very common in the local formations). The larger of the two looks like it has been worked over with a dremel or other aggressive prep tool. The human mind has the ability to believe anything is true. - JJ Link to comment Share on other sites More sharing options...
fifbrindacier Posted February 24, 2017 Share Posted February 24, 2017 I agree, both bivalves. "On ne voit bien que par le coeur, l'essentiel est invisible pour les yeux."

abyssunder Posted February 24, 2017 Share Posted February 24, 2017 I'm with JohnJ on these.
