genus of polycotylidplesiosaur , containing onespecies , "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 inLate Cretaceous ( earlyTuronian ) rocks in theHigh Atlas mountains ofMorocco in northAfrica . "Thililua" is the first Polycotylid plesiosaur discovered in Africa, and also the first discovered that lived at asubtropical latitude.Anatomy
The type specimen of "T. longicollis", which was described in
2003 , consists of an almost completeskull andlower jaw , articulated with 37vertebrae . Of these vertebrae, 30 were cervical (neck) vertebrae, which is an unusually high number compared to other Polycotylids, such as "Dolichorhynchops ", which had only 19 neck vertebrae, and "Polycotylus ", which had 26. It is believed to be an adult specimen, since some of thecranial sutures are very difficult to distinguish. Using comparisons with the head and neck length to body length ratio of a related genus, "Dolichorhynchops ", the estimated total length of "Thililua" was 5.5 to 6metre s.References
