Published Description

Holland (UGA Strat Lab, 2013):

  • Formerly: Agelacrinus pileus, Lepidodiscus pileus, Agelacrinites pileus
  • Includes: Carneyella cincinnatiensis, Carneyella nicklesi, Hemicystites curtus, Hemicystites richmondensis, Isorophus germanus, Bassleridiscus mowhawkensis

Sumrall (2010):

  • Carneylla pilea (Hall) is represented in the Maysville hardground by two large specimens (Fig. 3.3-3.4). These individuals are easily distinguishable from the locally more common Carneyella ulrichi Bassler and Shideler because they lack all hint of the large nodes that characterize C. ulrichi having instead fine rugose surface ornamentation consistent with the species assignment (Fig. 3.1). The width of the peripheral rim is also somewhat narrower. These specimens add no new information concerning morphology of the species.

Davis (1998) :

  • Edrioastroid. Differs from Isorophus cincinnatiensis in smaller size, fewer plates (especially over the mouth area at the junction of the ambulacra), and shorter, less curved ambulacra. Specimen slightly enlarged.

Fossils of Ohio (1996) :

  • Characterized by a single biseries of plates along the ambulacra and three primary orals.
