Abstract

Abstract : In north‐west Europe, the Permian is limited to the New Red Sandstone and the restricted marine facies of the Zechstein, yet elsewhere it is constituted of thick marine deposits with an abundant shelly fauna. One of the most notable sites for the marine Permian is the island of Timor in south‐east Asia, where thick, olistostromic blocks of limestone have yielded 1000+ shelly species. Over a third of these are stalked echinoderms, both crinoids and blastoids, two diverse Palaeozoic groups that would be devastated by the end‐Permian mass extinction.
