Summary

Description

Jimbacrinus bostocki Teichert, 1954 - fossil crinoid from the Permian of Australia.

Crinoids (sea lilies) are sessile, benthic, filter-feeding, stalked echinoderms that are relatively common in the marine fossil record. Crinoids are also a living group, but are uncommon in modern oceans. A crinoid is essentially a starfish-on-a-stick. The stick, or stem, is composed of numerous stacked columnals, like small poker chips. Stems and individual columnals are the most commonly encountered crinoid fossils in the field. Intact, fossilized crinoid heads (crowns, calices, cups) are unusual. Why? Upon death, the crinoid body starts disintegrating very rapidly. The soft tissues holding the skeletal pieces together decay and the skeleton falls apart.

Classification: Animalia, Echinodermata, Crinoidea, Articulata, Ampelocrinida, Calceolispongiidae

Stratigraphy: unrecorded/undisclosed Permian-aged unit (possibly the Cundlego Formation, Lower Permian)

Locality: unrecorded/undisclosed site near Jimba Jimba Station, western part of Western Australia
