Interpreting Sequences from Mastodon and T. rex

2007, Science

AI-generated Abstract

This research investigates the sequencing of ancient collagen peptides from fossil remains of Mastodon and Tyrannosaurus rex. The findings confirm that the collagen sequences from these ancient species closely resemble those of modern birds, particularly chickens, suggesting evolutionary connections. The implications of improved sequencing methods such as ultra-high-resolution mass spectrometry are discussed for future studies.
