Gennaeocrinus Crinoid Calyx Fossil



Here is a picture of a rare crinoid calyx fossil embedded in matrix. It appears to be a Gennaeocrinus kentuckiensis (Shumard, 1866). The specimen was found in the Beechwood Limestone of Clark County, Indiana, USA. This fossil dates to the Middle Devonian Period (Givetian).

Genus was named by Wachsmuth and Springer in 1881.

Thanks to Kenny for showing me the fossil.
