WEIRD THINGS FROM THE MIDDLE ORDOVICIAN OF NORTH AMERICA INTERPRETED AS CONULARIID FRAGMENTS

Abstract

Small phosphatic fossils recovered from acid residues of the Galena Group Middle (Ordovician) of Wisconsin were recently described by Clark et al. (1999) as weird things. Here, we report that specimens identified by those authors as Thing 3 and Thing 6 are fragments of conulariids belonging to two species that occur widely through Middle Ordovician strata of eastern North America. Similarly disintegrated, conspecific specimens from the Trenton Limestone of northwestern Indiana, and articulated, conspecific specimens from Ohio and New York, are introduced for comparison.
