Hello and welcome to!

 

I am not very good at recognizing fossil eggs, but in my opinion I think they are just rocks shaped like eggs.

But I'm really not sure, so let's see what others have to say, hopefully they'll have better news!

 

Warm regards,

Sorry no eggs, only shaped rocks...

[Troodon]

Agreed.  In trying to identify eggs one feature to look for an outer eggshell around a millimeter thick.  Dinosaur eggshells typically have some ornamentation on the surface and are not smooth.

 Not eggs, but the first two could be coprolites. If they are coprolites they would most likely be comprised of apatite (a type of calcium phosphate). It is really hard to definitively identify them as coprolites unless they contain bone/scale inclusions and/or retain surface features such as sphincter marks or folds. These are pretty abraded.  Were there other fossils in the area? If so, what type?
