Fossils

A handful of times in our planet’s history, the vast majority of plant and animal life has gone extinct, leaving a desolate and alien earth, devoid of trees, fish, and familiar signs of life. In the more recent past, scientists have pointed to asteroids to explain some of these extinction events. But today, that view is being questioned. More evidence is pointing towards terrestrial causes of our past extinctions, notably climate and ocean change, spurred by the influx of carbon dioxide in our atmosphere.


The fossil skeleton of a carnivorous dinosaur recently found in Wyoming was just auctioned off in Paris. Paleontologists are worried the sale is part of a trend that will keep specimens from our region out of the hands of scientists.

Bison fossils stored at the Idaho Museum of Natural History are getting a new life online as digital 3-D scans. It’s an attempt to make the specimens available to everyone.

New research shows that horse-sized, T-Rex-like dinosaurs roamed southern Idaho 100 million years ago. This discovery shows Idaho was home to more types of dinosaurs than previously thought.

Paleontologist L.J. Krumenacker has been digging up dinosaurs in Idaho for more than a decade. But in the past, scientists have mostly found small burrowing dinosaurs.

Working with a team of Montana State University paleontologists, Krumenacker found the teeth and small bones of three types of theropods, the family of animals that includes Tyrannosaurus Rex.
