Abstract/Notes | Pycnocrinus altilis n. sp. is described from the Upper Ordovician Georgian Bay Formation of Ontario. Closely related to P. dyeri (Meek), 1872, the cup of P. altilis is characterized by stellate ornamentation of plates comprising ridges bounded by deep subtriangular pits. Pycnocrinus altilis inhabited submarine channels in the prodeltaic regime of the Queenston deltaic complex and is inferred to have been anchored to the substrate by a distally coiled column. |
