Badlands yield another impressive fossil

By ERIC NEWHOUSE • Tribune Projects Editor • June 2, 2008

MALTA — Two weeks ago, the fossil-rich badlands about 20 miles south of the Canadian border in northcentral Montana yielded yet another dinosaur, a 75-million-year old brachylophosaurus. …

The brachylophosaurus was a mid-sized member of the hadrosaurid family with a bony crest over the top of its skull and a drooping over lip. An adult could be 25 to 30 feet long. It grazed on vegetation, but with powerful back legs was probably able to stand erect to eat leaves from the trees.

When this dinosaur lived here in the late Cretaceous period, northern Montana was a swamp, complete with fish, turtles and crocodiles, said Bakker. “There is no evidence of frost here,” he added.

“While there were plenty of crocodiles and turtles, there was only one common dinosaur: the brachylophosaurus,” said Bakker. “This is something that suggests that a natural disaster wiped out other dinosaurs, and there was some lag time before other dinosaurs filled in.

“But that’s my biggest mystery, why the other dinosaurs died out,” he said. “I can’t find any evidence of unusual droughts or flooding.”

A team of paleontologists and engineers has found that duck-billed dinosaurs had an amazing capacity to chew tough and abrasive plants with grinding teeth more complex than those of cows, horses, and other well-known modern grazers. Their study, which is published today in the journal Science, is the first to recover material properties from fossilized teeth: here.
