→5.4 cm long x 4.6 cm wide at widest point Basilosaurus pre-molar teeth This is a small but uniquely beautifulr Basilosaurus pre-molar in nice brown-whitish coloration with some interesting black lines & spots in it. This is a size specimen as Basilosaurus teeth can be much larger than that as well. There are four ridges on one side of the teeth and what it eroded away ridge on other side and the central main ridge. This pre-molar appears to be towards the end of the jaw as illustrated in photo of Basilosaurus jaw. 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. Basilosaurus molar roots are also usually unequal and assymetrical which adds to the uniqueness. The specimen illustrates 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 and one of the ridge has been rebounded as well. There is natural fault line which is prominent on one side of the fossil. Due to application of conservation material it has been re-enforced. So basically, this teeth is I a way professionally restored as well. Its possible that the fossil belong to another member of Basilosauridae family like Durodon or Zygorhiza. Please refer to photos for reference.
