        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.
