Scientific name: Unidentified Basilosaurid - (primitive whale ancestor) - Potencial cf Pappocetus lugardi or Zygorhiza kochii species- Canine Teeth. Location: Dakhla, Western Sahara, South Morocco Geological Formation: Samlat - Aridal Formation Age: Late Eocene (~40 Million Years) Size (The biggest -pre-molar): 6,5cm REF.: #J1009 DESCRIPTION: Two rooted canine teeth from Pappocetus lugardi or Zygorhiza kochii , a type of protocetid cetacean (early whale ancestor). These outstanding teeth come from the Middle Eocene-age Aridal and Samlat Formations, located in the Western Sahara near Gueran, Morocco. They're commonly found associated with teeth of the shark Otodus sokolovi (Carcharocles auriculatus), a megalodon ancestor. Observations about Restorations/Repairs/Comments: They have few glued amd filled fractures. Mainly on the basal part of the root. Despite these restorations, they are a truly magnificent enormous specimens. Pappocetus lugardi is an extinct species of protocetid whale that lived during the Eocene epoch (approximately 40–44 million years ago) in Africa. As a transitional form between land and sea, this amphibious, 20–25 foot long carnivore is considered an ancestor of Basilosaurus and represents a crucial stage in whale evolution. Key Facts About Pappocetus lugardi: Discovery: First described by C.W. Andrews in 1920 based on fossils from the Ameki Formation in Nigeria. Additional specimens have been found in the Sahara Desert in Morocco. Evolutionary Position: Pappocetus belongs to the family Protocetidae, which are early, amphibious whales that could likely move on land using their large limbs, while also being capable swimmers. Physical Characteristics: Size: Estimated to be around 20-25 feet in length. Diet/Habits: A large, amphibious, aquatic carnivore with robust teeth, likely relying on vision and smell for hunting. Appearance: More whale-like than its predecessors, with a streamlined body, yet retaining functional, though reduced, hind limbs. Fossil Record: Known from jaw fragments, teeth, and skull material. Relation to Modern Whales: While it was a transitional form, it is unlikely to have possessed the modern echolocation abilities found in later cetaceans.
