A fun timelapse video of the preparation of a massive 4” wide lower molar of an adult Titanothere from the Chadron Formation of South Dakota. I found this on a trip this summer with

@arsonlarson

and

@lawsonfossils

. The molar is a little weathered as it was exposed and sticking out of a cliff face when we found it. It’s actually prepped out really well though and has all its complete root system. Titanotheres or Brontotheriidae (also known as “Thunder Beasts”) were the massive horned herbivorous giants of North America during the Oligocene.
