These odd rodents belong to a genus known as Ceratogaulus, but they’re more commonly called horned gophers, because, you guessed it, they had horns. And it turns out the horns probably had a purpose one that rodents would likely benefit from today.

Samantha Hopkins’ 2005 paper on Ceratogaulus with figures featured in this episode (Thanks, Samantha!): https://royalsocietypublishing.org/do...
