This is a large and spectacular fossil canine fang with full root still embedded in the jaw of a large Miocene Era pinniped "sea lion" of the species Allodesmus kelloggi. The specimen comes from the famous Shark Tooth Hill deposits in California. The fang has colorful, speckled enamel of blue, gray, black and gold with a whitish gray root. The end of the root can be seen protruding from the inside of the jaw fragment. Some light feeding wear is evident on crown tip. The bone and tooth are in their original condition as fond. Tooth is original to the jaw as collected.
The rich Miocene fossil deposit known as "Sharktooth Hill" located in Bakersfield (Kern County), California has a reputation as the finest and most diverse fossil deposit of Miocene sharks, rays, bony fishes, turtles, birds and mammals (both marine and terrestrial) of the entire Pacific realm of North America. The formation is a result of silt spilling out of a prehistoric river delta into a Middle Miocene sea that once covered central California over 12 million years ago. This river originated in the nearby mountains east of Bakersfield. The fossil-bearing layer is thin ranging an average of only 6" - 18" thick but it spans approximately 100 square miles!
