Now he has. It is a landmark in the field. Horner said that because of the Willo study by North Carolina scientists, he and other researchers will now start doing CT scans on any intact dinosaur fossils they find. Among the effects of the heart discovery, said Horner, is a boost for the idea that birds evolved from dinosaurs, a theory that is becoming more widely accepted by paleontologists.
Birds also have four-chambered hearts.
In this week's issue of the journal Science, a team of North Carolina scientists published the first known images of a dinosaur heart, compiled from CT-scans of a dinosaur uncovered in South Dakota just east of the Montana line in 1993 and now on display at the North Carolina Museum of Natural Sciences. I think it's incredible. This means that dinosaurs were warm-blooded. That's a fantastic. It's way cool.
