A crinoid crown.

Submitted by: David Thompson
Taxon: Athroacantha carpenteri
Submit date: 2008-11-23
Location (approximate): Sylvania, Lucas, OH
Stratigraphy: Silica Formation
Age: Erian (Middle Devonian)
Submitter notes: Note the 'prickly' thorns at the nodes of the arms which along with the spines on the caylx made these rather hard to hold. Note the gold pyrite triangle in the front arms where there had been a platyceras attached but was broken off.
