Fossils from the Kohls Ranch locality of Gila County, Arizona, include bivalve and gastropod molluscs, brachiopods, bryozoans, crinoids, cnidarians and chondrichthyan teeth. [1] [2]
Illiniichthys is an extinct genus of prehistoric bony fish that lived during the late Moscovian stage of the Pennsylvanian epoch in what is now Illinois, United States. Fossils were collected from the Mazon Creek fossil beds. The genus is named after the Illini Native American tribe.
Nozamichthys is an extinct genus of prehistoric bony fish that lived during the late Moscovian stage of the Pennsylvanian epoch in what is now Illinois, United States. Fossils were collected from the Mazon Creek fossil beds. The first part of the genus name is Mazon spelled backwards, and the second part means 'fish'.
Aaglacrinus is an extinct genus of crinoidea in the Cladia order. It has been proposed that it was a stationary (attached) suspension feeder the hard parts of which were composed of magnesium calcite.

The Ada Formation is a geologic formation in Oklahoma, within and to west of Ada. It consist mainly of shale with numerous limestone layers which get thinner and eventually disappear to the south, where they are replaced by fine-grained sandstone. Fossils are rare. Disarticulated remains of Eryops, Diasparactus, and Ophiacodon from the Ada Formation represent the first finds of these genera in Oklahoma.
