Coprolite, concretion, or scute?

Recommended Posts

Reptilia

Hi there! 
 

These two rocks were found in the Aguja Formation. Wondering if they could be coprolite, concretions, some kind of scutes (unlikely), or meteorites? Material from the Aguja formation is very foreign to me, so I’m at a loss! They are rounded at the top and flatter at the bottom. Found amongst very large dinosaur bones. 

 

Thanks very much!

Lauren

I'm not familiar with that formation. I'm not really getting a coprolite vibe. Does it fizz if you put a drop of vinegar on it? I saw something similar a while back. When I looked at them under a microscope it contained bits of bone, decapod bits and invertebrate coprolites. Looking at the one with the tan underside, it looks like there might be some inclusions. My best guess is a burrow of some kind. Do you have a microscope?

You know, I have no idea but ...could it be an egg?
