New stegosaurus tracks found near Morrison

A new set of Stegosaurus tracks were found west of Denver, near Morrison, in the old Dinosaur Ridge fossil quarry. Scientists have reopened studies in this area, after closing them in 1879, when most of the fossils were shipped off to Yale. From the Post article:

Mossbrucker painted a picture of six or seven
species of dinosaurs - some as small as sparrows and others with the
combined bulk of eight elephants - making the imprints while walking in
wet river sand about 150 million years ago.

Aside from a system of shallow Platte-like rivers and shallow
ponds, the Morrison area's landscape in the Jurassic featured few
plants, a dry environment that served as an area to walk through to get
to someplace with more to eat.

An even rarer discovery is blocks of concretelike sandstone containing a combination of fossilized dinosaur bones and tracks.

Interesting too:

"You never, ever get footprints where you get
bones," said Robert Bakker, an internationally known paleontologist and
scientific adviser to the museum.

Mossbrucker is quoted in the Rocky:

"When I see these tracks, I half expect to look up and see a
stegosaurus walking away from me," he said. "That's how good they are."
