Well, #@#$%... The irony is that a skeleton from a baby Saltasaur
would make the thing the most complete titanosaur. Am I right in thinking
that Alamosaurus is still the most complete titanosaur, or have some
recent finds found anything better?
I dug up the article on Pelicanomimus, too, and it's a weird
creature. It has over two hundred twenty teeth, about seventy in the
upper jaw, the rest in the lower- weird. The first thing that came to
mind was "Piscivore!" but the descriptions didn't really seem to support
this. The front teeth were D-shaped, the ones further back, bladelike.
There are no serrations. It seems like the teeth themselves, however,
which are very small, serve as serrations for the jaw. The mention of the
integument was minimal, it mentioned a bit about fibers, which were not
clearly visible in the photos, and a possible throat sack (though this
could be a dewlap, as well, you'd think). Another weird thing about the
teeth- the teeth in the upper jaw were all on the front half, the back
was toothless. I didn't find the description of the integument any more
enlightening than the photos. The thing is some kind of ornithomime,
according to the authors. From the Lower Cretaceous of Las Hoyas, Spain.
Has anybody heard any ideas about exactly what this animal ate? Or any
further stuff on the feathers?
