As herbivores, these animals had large teeth for grinding their diet of plants.

“These mammals can have enamel two to three millimeters thick. It was a lot of material to work with,” Dr. Green said.

“Nobody’s ever found peptide fragments that are this old before.”

Until now, the oldest published materials are about 3.5 million years old.
