The Kakuru is an ancient dinosaur that probably lived during the early Cretaceous period on earth. Their fragmentary fossil specimen was discovered from a part in South Australia. Therefore, this ancient genus was believed to be a part of the South Australian ecosystem. The name Kakuru is quite an unusual name for a dinosaur. The genus Kakuru was named by Molnar and Pledge after the Australian mythological character called the rainbow serpent and the species is named after an aboriginal tribe called Guyani.

Molnar and Pledge assigned them as theropod dinosaurs but their broader classifications were uncertain. Therefore Pledge and Molnar regarded it as a Theropoda incertae sedis. The fossil remains of the dinosaur mainly consisted of a tibia or the shin bone. The tibia was recovered from the opal field of Andamooka. The long length of the tibia indicated that the dinosaur probably belonged to the Coelurosauria order consisting of feathered dinosaurs. However, they had a high ascending astragalus which was more of an  Abelisauroidea clade characteristic. To know more facts about the dinosaur, keep on reading these amazing facts.
