Unlike other feathered dinosaurs
, however, this species was not a theropod.
67 million years ago, before the dinosaurs
ruled the earth, the atmosphere contained nearly 35 percent oxygen, enough to make you giddy.
Unfortunately, though, some students only study dinosaurs
in kindergarten and there are many young students, who may want to become paleontologists, but never get a chance to study fossils in school.
