5 rare and hard to obtain anal sacs that graced a crinoid approximately 300 million years ago. I have been told that these are anal sacs or calyx however I am not an expert by any means and would appreciate any feedback you fossil buffs have.

Geologic Age:   Permian

Stratigraphic Detail:  Sonnebait Formation, Basleo Faultline

Location:    Timor, Indonesia

The Permian of Timor in the Lesser Sunda Islands has attracted the attention of palaeontologists since the middle of the nineteenth century because of the richness, diversity and excellent state of preservation of its fauna.  The Permian rocks of Timor were deposited on the northern margin of Australia.  The region of Timor was involved in a continent–arc collision, where Australia collided with the Banda Arcs.  As a result of this collision, Permian rocks of the Australian margin have been disrupted by folding and faulting with generations of mud-matrix mélange, and uplifted to form part of the island of Timor.  This has an elevation of about 4,000 feet where they were found. 

Timor is described as an “uplifted, faulted margin of the former Australian craton, composed of Permian to Cretaceous aged rocks. Miocene and lower rocks form a thin layer in some areas”
