An articulated skeleton of the fossil dog Cynarctus has been revealed at the Ashfall Fossil Beds. Cynarctus fits into the subfamily of Canids known as Borophaginae, an extinct group - some of which are referred to as “bone-crushers”. Cynarctus and a few of its allies appear to have had an omnivorous diet; with dentition similar to Procyonthe modern raccoon. The skeleton, as well as a complete skull and mandibles of a separate individual also recovered from the volcanic ash bed, are the well-preserved remains of a species otherwise poorly represented in the fossil record.
