The alien looking Jimbacrinus bostocki crinoid fossils were first discovered in 1949 by the manager of the Jimba Jimba cattle station in Western Australia. As you can see the genus name is derived from the property name where they are located. The Jimba Jimba station managers name was Mr J Bostock, who the fossil species has been named after.
These fossils were then further collected by fieldwork geologists from the Bureau of Geology, and transported to Melbourne. A paper first describing these fossils was published in the Journal of Palaeontology in January 1954. This paper was authored by Curt Teichert of the University of Melbourne, Victoria, Australia.
The Cundlego Formation where these fossils are found, is a sandstone formation that was created by flooding and storm event deposition during the Early PERMIAN – approximately 275 million years ago. This deposit was found along a dry creek bed and is filled with the fossilized remains of the abundant bottom dwelling species of the time.
These fossils are often found complete and have not been found elsewhere.
