What you describe sounds like the alleged Tyrannosaurus bataar eggs.  
If true, I suspect that the eggs were bought in the past year or two.  
Most likely they came from the Maastrichtian of China, possibly Henan 
Province.  No one has yet described an embryo that would prove the eggs 
are those of T. bataar.
