In Depth

       The discovery of Attenborosaurus was unorthodox to say the least.‭ ‬When first discovered the remains were referred to the Plesiosaurus genus as a new species,‭ ‬P.‭ ‬conybeari.‭ ‬These remains were destroyed during a bombing raid in World War II,‭ ‬but a plaster cast of them was made before this happened which has meant all but the original skin impressions can still be studied.‭ ‬This plaster cast was enough to bring the realisation that while similar to Plesiosaurus,‭ ‬the remains are different enough to warrant the creation of a new genus‭; ‬Attenborosaurus.

       As you may have already gathered from its association with Plesiosaurus,‭ ‬Attenborosaurus had the small head,‭ ‬long neck,‭ ‬round body with four flippers that are associated with all plesiosaurs.‭ ‬As Attenborosaurus approached shoals of fish it could use its long neck to reach in and snap up a fish,‭ ‬the sharp teeth in the mouth granting Attenborosaurus a secure grip upon its prey.‭ ‬The skin impressions with the original fossils are noted as being a smooth membrane that was devoid of any noticeably large scales.‭ ‬This smooth skin probably helped to streamline Attenborosaurus as it swam through the water by‭ ‬reducing drag from water resistance.

       Attenborosaurus is named after the Sir David Attenborough,‭ ‬who is perhaps best known for narrating a huge amount of BBC nature documentaries.‭ ‬The species name is derived from the original Plesiosaurus conybeari,‭ ‬which itself was named after William Conybeare who was one of two people who named the Plesiosaurus genus back in‭ ‬1821.
