“…Our understanding of the morphology and phylogenetic inclusiveness of edrioasterids (Echinodermata) has been greatly enhanced over the past few decades. Bassler (1935, 1936) presented a classification dividing edrioasteroids into five families: Stromatocystitidae, Hemicystitidae, Agelacrinitidae, Edrioasteridae, and Cyathocystidae, and this classification was followed by Regnéll, (1966). Kesling (1967) added Pyrgocystidae to this scheme to accommodate taxa with a flexible, highly extendable, peduncular stalk.…”

The new edrioasterine Pseudedriophus guensburgi n. gen. n. sp., is described from the Lower Ordovician Ninemile Shale of central Nevada based on three complete to partial small specimens, a well-preserved large ambulacrum, and an isolated ambulacral floor plate. The weathered-out holotype of this edrioasterine exposes the bottom surface of the theca that bears an aboral collar, peduncular stalk, and attachment disk, features that are poorly known in this clade. These specimens were found with a single specimen of a new edrioblastoid, Porosublastus inexpectus n. gen. n. sp., only the second edrioblastoid ever found in the Early Ordovician. Some of the ambulacral cover plates are stripped off one of the ambulacal grooves, revealing new information about how the ambulacra are built in this rare group of bud-shaped edrioasteroids.

“…T HE LATE history of edrioasteroids has come to light only in the last 40 yr. When the edrioasteroid chapter of the Treatise on Invertebrate Paleontology was published (Regnéll, 1966) the youngest known edrioasteroids were upper Mississippian (Chesterian). Since that time, a series of papers have described edrioasteroids in the Pennsylvanian (Fraunfelter and Utgaard, 1970;Bell, 1976;Sumrall, 1992;Sumrall and Bowsher, 1996;Sumrall et al, 2000Sumrall et al, , 2006.…”

Pennsylvanian edrioasteroids now include nine species distributed among six genera, including one fauna bearing four genera (Sumrall et al., 2006). These edrioasteroids are not limited to a single clade but include postibullinids, plesiomorphic agelacrinitids, and derived clavate discocystinids.
