Zarafasaura

Summary

Zarafasaura is an extinct genus of elasmosaurid known from the Ouled Abdoun Basin of Morocco.[1] As a relatively small elasmosaur, it would have measured around 3–4 metres (9.8–13.1 ft) long and weighed about 100 kilograms (220 lb).[2][3]

Discovery edit

 
Life restoration

Zarafasaura was first named by Peggy Vincent, Nathalie Bardet, Xabier Pereda Suberbiola, Baâdi Bouya, Mbarek Amaghzaz and Saïd Meslouh in 2011 and the type species is Zarafasaura oceanis. The generic name is derived from zarafa (زرافة), Arabic for "giraffe" (it refers to the name given by the local population to the plesiosaurs found in the phosphates) and saurus, Greek for "lizard". The specific name is derived from oceanis, Latin for "daughter of the sea".[1]

 
Skull diagram

The holotype of Zarafasaura, OCP-DEK/GE 315, consists of an articulated incomplete dorsoventrally crushed skull and mandible and from the paratype OCP-DEK/GE 456, a complete mandible. It was collected in the Sidi Daoui area, from the Upper CIII level of the upper Cretaceous (latest Maastrichtian stage) Phosphates of Morocco.[1] In 2013, a second specimen, WDC CMC-01, was found to have a more complete skull with previously unknown postcranial elements such as the forefins, hindfins, vertebrae, pectoral and pelvic material.[4]
