ULTRA RARE METAXYTHERIUM TUSK FROM A MIOCENE ERA SEA COW

Dixie Co. - Florida, USA

MIOCENE PERIOD:  23 - 5.3 million years ago

This is an extremely rare tiny front tusk of an extinct Miocene Period sirenian called MetaxytheriumMetaxytherium was a prehistoric dugong (sea cow) that lived in coastal waters and inland waterways, fighting for its survival amongst the existence of the giant killer Megalodon shark.  It is most likely that Megalodon relied on Metaxytherium as an easy kill and these slow-moving dugongs were probably an important staple in the Megalodon's diet.  Often, Metaxytherium bones are found with shark bites on the surface and the bones are found in areas where many prehistoric shark teeth are found like Megalodon.  Metaxytherium fossils are common in the southeastern United States but mostly in the form of their bones such as ribs.  Even in the few rare instances where a skull was found, these small front-most tusks are usually missing.  If you collect tusks, this magnificent rare gem will most likely, classify as one of your rarest specimens amongst a collection.  The richest Metaxytherium fossil deposits are in Florida where our company is based and despite seeing an incredible array of rare fossils over the years, this is the FIRST time we have seen a tusk like this.

The specimen is in superb, intact condition with no breakage, full enamel surfaces, very minor natural wear on an unbroken tip and even a partial root.  It is solid and well mineralized.  An incredibly rare fossil tusk in complete form.  INTACT WITH NO REPAIR and NO RESTORATION.  

Sirenians first appeared in the Eocene and eventually spread world-wide through various time periods mostly preferring warm water environments.  Interestingly enough, Florida is the only area in the world that can boast of continual habitation of sirenians since the Eocene!  Fossil remains in the state represent all known sea cow families that ever existed!

Due to the extreme buoyancy of the creature, sea cows have very dense bones that lack marrow cavities or spongy internal structure.  This allows their skeletons to act as ballast thereby offsetting their buoyant body mass.  They are exclusively herbivores and are highly docile creatures allowing human contact in the wild.
