Mosasaur tooth- M.Hoffmannii aff, 99.6-66 Ma, Cretaceous. Khouribga, Morocco.

with the lack of prisms to this tooth and taking into account the size I am confident that this tooth can from one of the largest Predatory mosasaur species known as M.Hoffmannii. Although little is know about this Cretaceous monster of the deep it has been estimated, from little remains found that Hoffmannii could have probably reached lengths of over 50ft. This is a superb rooted tooth and even featured the resorption pit (The depression showed on the root) Mosasaur would replace teeth often, the apsorbtion pit is the depression from the next tooth inline waiting to erupt. Often at this point we see hairline cracks. 

This tooth was located and found at Ouled Abdoun basin, Khouribga, Morocco.
