Dear Dr. Campbell
Yes... I have the same impression about the paleontological information
published on Sciences and Nature. In fact I´m involved in the study of an
extraordinary fpssil assemblage from México (The Tlayua Quarry) were the
fishes show the same kind of preservatoion as in the Santana fossils from
Brazil... For the first time in North America we have Cretaceous fossil
fishes with soft tissues phosphatized... and in some of them the bloody
system is preserved as lines of red color along the ventral border of the
vertebral colum taht in some cases in extended into the anterior part of
the abdominal cavity.......probably here we can get some proteins, older
than those found in T. rex bones....
