 Description: Globidens is one of the most rare of
marine reptiles and is characterized by a massive, bulbous dentition
far different from those of most other mosasaurs. Indeed, the species
derives its name from these most unusual teeth (globidens= globe tooth).
Rarity of the taxon coupled with the unusual dentition has prompted
a number of theories about life style. Most theories suggest the dentition
was utilized for crushing resistant elements such as turtles or pelecypods
or perhaps for scavenging. Specimens of this 6 meter long mosasaur
have been found in North America, Europe, Africa, the Middle East,
and South America. One specimen from South Dakota’s Pierre Shale
has been found with the remains of crushed shells from the giant Pelecypod
Inoceramis within its stomach region, attesting to its taste for “clam
on the half shell”. This one has a portion of the root present;
most I havew seen appear to be shed teeth. |
