Besides dinosaurs, the Cedar Mountain Formation has produced a wealth of small fossils (a.k.a. microfossils), mostly teeth from a variety of vertebrates.
For example, a widespread layer, up to 1 m (3.3 ft) thick, of rhythmically bedded carbonate-chert, called zebra rock, occurs near the base of facies 2. The bed of zebra rock often grades upward into a 20 cm (7.9 in) thick bed of rippled and cross-laminated carbonate sandstone that exhibits well-defined linear, to bifurcating, ripple crests ...
