These marine creatures, also known as sea lilies, lived during the Permian period. The fossils are usually found complete and have not been uncovered in any other location. They were first discovered in 1949 by the manager of Jimba Jimba cattle station, for which the genus was named.
The Permian period was the final period of the Paleozoic Era, lasting from 298.9 million to 252.2 million years ago. The climate was warming throughout Permian times, and, by the end of the period, hot and dry conditions were so extensive that they caused a crisis in Permian marine and terrestrial life.
