From the album: Badlands, Nebraska megafauna.
The two associated Hyaenodon horridus mandibles from Nebraska puzzled me because they appear to be from an adult but when I removed some matrix i saw gaps for a molar and a tip of a tooth peeping out. I looked into it and it seems that the last molar doesn't reupt until age 3-4 so that is roughly the age of this animal. To verify, I asked a good mate to xray it. Th huge erupting molars are clearly see in the imagine. You can also clearly see the tooth roots below the crowns of the teeth and below the gum line (ie embedded into the bone). You can also clearly make out the mandibular canal (long dark line running ventrally below) the teeth - it's where the major veins, arteries and nerves of the bone run. Great view of millions of years old bone and teeth! Confirms that the teeth are erupting molars and gives me a great idea of the age. Not, quite juvenile, more like subadult. -

This mesohippus jaw was found near the Hyaenodon. Not sure of species yet but I believe it to be a three toed horse. -

Opinion on fossil jaw
HeartandFist posted a topic in Is It Real? How to Recognize Fossil Fabrications
I purchased this fossil Globidens jaw fragment at a Gem and Mineral Show about a month ago. The crown of the tooth appears to be real, as does the jaw bone. Being cautious of Moroccan fakes, I made sure not to pay too much for the piece. While the individual parts appear to be genuine, I have noticed repair marks and markings that suggest the tooth may be composited onto the root. Any opinions or insight into the matter would be greatly appreciated. Thanks! - Geoff
