Five Alian-Looking Jimbacrinus Crinoid Fossils - Australia
These Jimbacrinus crinoids are hard to acquire due to Australia's strict fossil export laws. This specimen was exported legally during the 80's and was in a collection for year before being recently re-prepared.
Crinoids, sometimes commonly referred to as sea lilies are animals not plants. They are echinoderms related to starfish, sea urchins and brittle stars. Many crinoid traits are like other members of their phylum. Such traits include tube feet, radial symmetry, a water vascular system, and appendages in multiples of five (pentameral). They first appeared in the Ordovician (488 million years ago) and some species are still alive today.
