Scientists
have found the fossil of a squirrel-tailed dinosaur with feathers that
challenged the image of the dinosaurs as giant lizards:
Previously, paleontologists have found feathers only on coelurosaurs—birdlike
dinosaurs that evolved later than so-called megalosaurs such as Sciurumimus.
Because Sciurumimus is not closely related to coelurosaurs, the
new fossil suggests feathered dinosaurs were the norm, not the exception,
Rauhut said.
"Probably all dinosaurs were feathered," he added, "and
we should say good bye to the familiar image of the overgrown lizards."
