→6.6 cm long x 3.5 cm wide at widest point Basilosaurus pre-molar teeth This is a very beautiful, medium size Basilosaurus pre-molar in nice brown-chocolate-yellow coloration. We have seen similar pre-molars with lots of white lines on it which are attributed to plant roots interacting wit the fossil over million of years but in this fossil there are just 2 or 3 such lines or one can say those are virtually absent and hence the teeth is in its distinctive coloration. The crown of the teeth is in chocolate brown color while the root region is in light color. We think the teeth is the 2nd pre-molar from front of lower jaw as indicated in illustration. The ridges in the teeth are all intact and in excellent shape. There is one central ridge and 3 small ridges on either side. Basilosaurus molars are asymmetric and this asymmetry is evident here as well. The root legs are asymmetric as well as the ridges are asymmetric and over teeth does not have a 100% central symmetry either. 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. Our close inspection reveals that the teeth is in natural state without restoration or repair. This makes it an excellent specimen as repair or restoration is common is Basilosaurus fossils. In short, its a very beautiful specimen. The standing and side way laying down photos are very nice to look at. It looks like a standing person or person leaning against a wall. The teeth gives good feeling to hold it in hand. Its possible that the fossil belong to another member of Basilosauridae family like Durodon. Please refer to photos for reference.
