The following pictures are of a fossil collected near Chadron, Nebraska circa 1971. I have received opinions that it could be the base of an Archaeotherium or Brontotherium skull. There are several small teeth on the matrix, I presume they are unrelated. I would appreciate any information anyone can give me about it.
Thought I'd share a few photos of a tortoise prep I just completed. This is from the white river group of Chadron, NE (circa 33 mya). Here is a series of photos from discovery to excavation to restoration and preparation. The discovery: broken shell (As usual, I forgot to take a true "before photo". I've already probed a bit here). After some digging, it was discovered that this individual is upside-down. Here, the plastron is being revealed.
