Brachylophosaurus canadensis 78 million years old One of the so-called duck-billed
dinosaurs, this creature's genus name means "short-crested
lizard"—so-named for a flat, paddle-like
plate on top of its skull. Within their specimen, the team found highly
fragmented though still pliable blood vessels containing pigmentation and
possible red blood cells. Overall, the findings in this and planned future
studies could shed new light on how dinosaurs evolved, how their blood vessels
and muscles worked, and that age-old question: whether or not they, unlike
other reptiles, were warm-blooded.
