Taxonomy
Nasogaluakus chorni was named by Schultze (2000) [A holoptychiid with a combination of two primitive porolepiform features (anterior margin of parietals behind orbits. parietal does not contact supraorbital) not present in other hoIoptychiids and two known holoptychiid features (anterior position of posterior pit line on postparietal and loss of cosmine): boomerang-shaped tabular which is anteriorly twice as wide as posteriorly, one large supraorbital and one large subsquamosal.]. Its type specimen is CMN 51129, a skull (flattened and somewhat disarticulated skull), and it is a 3D body fossil. Its type locality is Standard Oil Co. locality no. AR.25.58, which is in an Emsian lagoonal/restricted shallow subtidal lime mudstone/dolomite in the Bear Rock Formation of Canada.
