Prepping a giant beaver (castoroides) skull and mammoth femur for the Dark River Artifact and Fossil show in Leavenworth KS on April 12th. I'm plannning on having he castoroides skull restored prior to the show. #fossil #fossils #fossilhunting #fossiladdict #mammoth | Bison Bison Paleo Fossils

I've read that the castoroides (giant beaver) was the approximate size of a black bear. This is my castoroides skull with a 250lb black bear skull on the left and a trophy African lion on the right. #fossilhunting #pleistocene #Iowa #fossil | Bison Bison Paleo Fossils

Jack is in Nebraska and I highly recommend him for restoration work. #fossilhunting #bisonbisonbison #fossils #outdoor #pleistocene | Bison Bison Paleo Fossils | Facebook
