Lance creek repaired

[MSirmon]

I received this shattered baby in a field flat of fragments I ordered through an online trading site out of the Lance Creek formation. Pardon the crude repair but it is a work in progress and my first major undertaking. Trying to see if anyone can help identify what it is.

Nice repair. Even so, a chunk like this will be hard to identify to say the least. There aren't exactly a lot of diagnostic features present on it.

from one of the shots it looks to be a larger, flatter bone so perhaps the scapula or some hip element? If so it would probably be from Triceratops or Edmontosaurus but from just one assemblage of fragments it would be hard to tell.

Nice repair job! 

Not sure what it is, though.
