Lo ha cambiato alla mostra di Millau in Francia.
Coprolite (cacca) ?? provenienza Utak USA Giurassico.
È possibile una migliore indicazione?
Grazie, Michele

We still do not know if rocks like this from Utah are really coprolites. It is possible that it could be a cast of a coprolite. Unless there are identifiable inclusions such as vegetation, bone, scales, teeth or other evidence of items consumed, it is impossible to know for sure at this time.

I would find it very hard to believe this was a coprolite. Extruding an external texture like that is very hard to conceive. For the same reasons Lori gives, I'm gonna poopoo this one as a coprolite.

No it is not a formation (corollaoid).
I remember Tucson that he saw Utak copolites that looked like.
Thank you

Beware of those Utah "coprolites." I know of no one who actually works on coprolites who considers these to be real coprolites. They are called that at rock & mineral shows because they will easily sell as "dino dung" but not as well as "amorphous silica formation." Caveat empturd.

I'm not sure that intestinal muscles would produce a such irregular shape.

I'm leaning like the others towards a coralloid concretion or an earth poop.
