Abstract

The steinkern of a camerate crinoid found in rocks of Middle Pennsylvanian age is of considerable interest in that very few genera or species have been reported. Megaliocrinus johnsoni, new species, is from the Cherokee Group, exposed in the Collinson quarry near Milan, Rock Island County, Illinois. Internal nerve canals radiating from the chambered organ are preserved as ridges.
