2.3" Fossil Crinoid and Gastropod Plate - Crawfordsville, Indiana
This is a beautiful Barycrinus stellatus and Pachylocrinus aequalis crinoid association from the Edwardsville Formation of Crawfordsville, Indiana. The crinoids are preserved alongside a gastropod fossil (Platyceras equilateralis). The quality of preparation on this fossil is exquisite, using skillful air-abrasion techniques under a stereo microscope.
It comes with an acrylic display stand.
#5 - Barycrinus stellatus (1.1" wide)
#35 - Pachylocrinus aequalis (.9" long including stem)
#92 - Platyceras equilateralis gastropod (1.3" long)

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.
