DESCRIPTION:
Pappocetus is a protocetid and a large amphibious aquatic carnivore. Pappocetus is also an ancestor of Basilosaurus. Rare specimen from an early evolutionary stage of the modern whale. In the phosphate basins of the Moroccan Western Sahara, the fossil record of these enormous vertebrates is very well represented, of this type of cetaceans that speak of an evolutionary transition from land to sea.The protocetids had large fore-limbs and hindlimbs that could support the body on land, and they were most likely amphibious capable of living on land and in the sea.
Nicely preserved specimen still on its jaw bone. It only has some glued and tiny filled fractures.
