In contrast, Asara's team had only those seven T. rex protein sequences to work with, and it turned out all of them matched up with modern-day sequences.

"Out of seven total sequences, we had three that matched chicken uniquely," Asara told reporters. "We had another that matched frog uniquely, one that matched newt uniquely, and a couple that matched multiple sequences."

The bottom line was that the T. rex's biological signature was most like a bird's, at least based on the first fragmentary data. "It looks like chicken may be the closest among all species that are present in today's databases for proteins and genomes," Asara said.

Now to see the same done with hominids.
