3.6" Fossil Crinoid, Brachiopod, Coral & Bryozoan Plate - Indiana

Fossil Crinoid, Brachiopod, Coral & Bryozoan Plate - Indiana #291829

This is a beautiful, 3.6" wide plate of detailed crinoids, brachiopods, coral, and bryozoan fossils from Crawfordsville, Indiana. These fossils have been microscopically prepared using air abrasives, revealing their intricate details and three-dimensional preservation.

It comes with an acrylic display stand.

#47 - Scytalocrinus decadactylus (1.4" long)
#54 - Agaricocrinus americanus (1.3" wide)
#69 - Macrocrinus mundulus (anal tubes both .8" long)
#110 - Cladochonus beecheri (coral .85" wide)
Unidentified brachiopods (1.2" wide & .55" wide)
Unidentified bryozoa (1" wide & .9" wide)

Crinoids from the Ramp Creek Limestone were likely buried in sediment from nearby deltas during storms. The resulting siltstone deposits are soft enough that fossils can be extracted in exquisite, three-dimensional relief.

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.
