This is a picture of an eroded crinoid calyx fossil. It appears to be a Dolatocrinus. The fossil was found in the Jeffersonville Limestone of Clark County, Indiana, USA. It dates to the Eifelian, Middle Devonian Period.
Thanks to Kenny for the picture.

I believe the is actually a Megistocrinus rugosus. The bottom plates are worn away a little. Kenny
