Kakuru kujani

Kakuru is a dubious genus of theropod dinosaur from the Early Cretaceous of Australia.

==Discovery== thumb|left|Left tibia The only described species, Kakuru kujani, is known primarily from evidence of a single tibia, which had been fossilised through a rare process in which the bone through hydration turned to opal. The bone was dug up at the opal fields of Andamooka, South Australia. The opalised tibia was exhibited by a gem shop in 1973 and by chance brought to the attention of paleontologist Neville Pledge. The owner at the time, a certain A. Fleming, allowed pictures and two casts to be made but eventually the specimen was sold at an auction to an anonymous buyer. It was presumed lost to science. In 2004, however, the South Australian Museum succeeded in procuring the fossil for $22,000.
