A species of ancient beaver that was rediscovered by researchers in the University of Texas at Austin’s fossil collections has been named after the beloved chain Buc-ee's — known for its toothy cartoon beaver mascot.

Details: Anchitheriomys buceei lived in Texas about 15 million years ago and would have looked similar to beavers today — except it was 30% larger than modern beavers.

What happened: While driving down a highway in 2020, Steve May, a research associate at the UT Jackson School of Geosciences, spotted a Buc-ee’s billboard that said "This is Beaver Country."

  • The phrase brought to mind the Texas beaver fossils he had been studying, per a UT news release.

What they're saying: "I thought, 'Yeah, it is beaver country, and it has been for millions of years,'" May said.
