→9 cm long x 4.6 cm wide at widest point Basilosaurus pre-molar teeth →Weight 37 grams This is a very beautiful, medium-small form factor Basilosaurus pre-molar in nice brown-chocolate-yellow coloration with some interesting white lines and spots in it. These white lines are attributed to interaction of fossil with plant roots during the fossilization process eventually leaving these characteristic white lines. There are many Basilosaurus teeth in light brown color but this specimen has more dark tone to it making it unique in its own way. This is a medium-large size specimen as Basilosaurus teeth can be much larger than as well. We think the teeth is the 2nd pre-molar from front of lower jaw as indicated in illustration. There are four prominent ridges on each side of the teeth and one main central ridge. The pre-molars had the key role in chewing and shearing of the flesh from the prey in the Basilosaurus jaw as Basilosaurus was top predator during the late Eocene epoch, approximately 41 to 33.9 million years ago and lurked in the shallow coastal seas. Some part of outer layer of root is eroded giving a peek into side of the root which in technical terms is dentin of the teeth. The specimen shows how a biological specimen which in this case is a teeth gets converted to rock and geological material during the fossilization process over million of years. The teeth has been professionally conserved to make it long lasting. As one can see on both side of the teeth that restoration material being applied to fill the cracks and make the teeth long lasting as these fossils are found in hard ground either in broken form or during retrieval they can develop cracks so restoration is must. In anyone , its a very beautiful specimen. The standing and side way laying down photos are very nice to look at. The teeth is light and gives good feeling to hold it in hand. Its possible that the fossil belong to another member of Basilosauridae family like Durodon or Zygorhiza. Please refer to photos for reference.
