What is "thililua"

Thililua is a genus of polycotylid plesiosaur, containing one species, T. longicollis. The name Thililua is derived from that of an ancient aquatic god from local Berber mythology; longicollis refers to the animal's long neck. Thililua has been found in Late Cretaceous (early Turonian) rocks in the High Atlas mountains of Morocco in north Africa. Thililua is the first Polycotylid plesiosaur discovered in Africa, and also the first discovered that lived at a subtropical latitude. In 2010, Thililua was transferred to Leptocleididae as a sister taxon to Nichollssaura.
