Fossil ammonites found in the North State range in size from half an inch to 18 inches across, Reed said, but some found in other parts of the world are as big as three feet across. They represent the ostracod association of the present study. Ostracod associations coming from the Upper Triassic (Tropites subbullatus/Anatropites spinosus zones of the Tuvalian substage) clays and sandstones of the Mufara Formation outcropping along the west side of Monte Gambanera (Castel di Iudica, central-eastern Sicily) have been analysed for the first time.
