Well-preserved Lower Ordovician graptolites in the Ibex region of Millard County, Utah, include 45 species from 13 genera. Of these, 15 are new and described and named; 26 were collected in great enough numbers to be accurately identified and statistically analyzed, and 12 have excellently preserved ontogenetic and/or early astogenetic developmental stages, descriptions of which add considerably to our present knowledge of graptolites of Early Orodovician age.
