→12.4 cm long Basilosaurus pre-molar teeth →6 cm wide at the widest point →170 grams It is a beautiful, top quality and large Basilosaurus pre-molar teeth. This teeth is a true symbol of enormous size and bite force of Basilosaurus as it ruled the shallow seas in late Eocene Epoch, approximately 41 to 34 million years ago. This amazing teeth features 6 major side cusps or ridges and the central main ridge along with 2 small additional side cusps or projections. These ridges are key in shearing and cutting the prey which included marine life like fish, Durodon and other animals who came near water or lived in the swamps nearby like Moeritherium for example. The crown of the teeth is in nice light chocolate brown color while the root region is light yellow-golden color. As one can notice, the teeth is double rooted, which again is characteristic feature of Basilosaurus pre-molars. The roots are also quite large as can be clearly seen in the photos. The teeth is in natural state and if one loks at the top central ridge there is change in color giving an impression that it is composite but it is absolutely not the case. It is purely due to fossilization process probably the top central ridge got used and eroded during the Basilosaurus lifetime and when it got fossilized it got different brown tone than the surrounding region. Although its a fossil where biological tissue is replaced by rock & minerals, still the root region has looks and feel of a bone to it making it very cool especially when hold it in hand and look at the underside and sides of the root region. A small elliptical region is eroded in the root region giving an insight into inside of the root layer of the teeth probably its the dentin of the teeth. Similarly a small portion in the enamel of the teeth is also eroded, revealing the layer below. The unique mix of fossilization, mineralization are very nicely revealed in this fossil. This fossil truly shows what is fossilization and how biological is converted to geology in fossilization process over million of years. The fossil also looks like a standing man in one of the photos giving it interesting looks. The teeth is in natural state and to best of our inspection it is not restored or repaired. The teeth has been professionally conserved as well to make it long lasting. Please refer to detailed photos for reference. Different photos have been provided to give an idea about the shape, size, color and other features of this fantastic fossil.
