Tiny dino a huge discovery
By MARTIN J. KIDSTON IR Features Writer
The badlands revealed another scientific prize this month to a Montana State University undergraduate student who found the skull and frill of a baby triceratops on a dig near Jordan.
Jack Horner, curator of paleontology at the Museum of the Rockies in Bozeman, announced the rare discovery Thursday and believes it will help paleontologists better understand dinosaur development.
“It was a baby,” Horner said. “It really was less than a year old.
The orbital horns are only about three or four inches long.”
The skull was found at a dig near Jordan by Sonja Scarff, an undergraduate student at Montana State University. Scarff was working on a field crew under Horner’s direction.
