The plant and trace fossils of Dinosaur Ridge, Morrison, Colorado, are given further descriptions. Most of the plant fossils in this outcrop of the Dakota Formation are in the form of broken pieces of charcoal or as casts, which often record the wood grain. Charcoal fragments mixed within the sand are interpreted as being deposited under catastrophic conditions. Rocks containing the charcoal along bedding planes are interpreted as being deposited under conditions slow enough to allow buoyancy to separate the plant matter from the rock detritus.Charcoal fragments were also present in the upper third of the Dakota Formation in the local region near Dinosaur Ridge, at Canon City, Montrose, and Fort Collins, Colorado, and at Newcastle, Wyoming. The charcoal appears to be catastrophically deposited in the region of Dinosaur Ridge and at Newcastle. Further observations and research may fit these widespread deposits into the middle to upper part of Flood strata.
