We have a pair of tyrannosaurid eggs in the geology museum here at
ASU. The species and genus are unknown (I haven't spoken with Dr. Dietz
about these eggs, so I can only tell you what it says on the display
placard.) The two eggs are pretty broken up, but the basic form is
rather like a pair of giant Tylenol. They're about 16 inches long, but I
imagine they would be compressed to 12 inches or so if they weren't so
broken up. The matrix has only been partially removed from them, so they
are still oriented as they were found. They lie almost parallel to one
another, and at first glance look like the counter-piece of a two-toed
footprint. I do not know if more than these two eggs were found.
Locality? Horizon? Age? Sorry, I don't know, but it wouldn't be difficult
to find out if someone wants more info.
