Feature Fossil Find of 2017

A variety of new finds were unearthed in the Hubbard Rhino Barn in 2017. Two skeletons of three-toed horses (one of which is intact) as well as other finds of interest including a partial camel skeleton (a rare find in the Rhino Barn), a number of fossil tracks from bone-crushing dogs that scavenged the carcasses during the volcanic ash storm, and a scattering of bone from a rhino calf.


A stunning fossil was found in the 2016 season. Ashfall Fossil Beds summer intern Mikayla Struble (Montana State University) was conducting work in the Hubbard Rhino Barn when she uncovered the skull of a three-toed horse skeleton identified as Pseudhipparion gratum.
