Next stop on the Dinosaur Diamond: Moab. My GeoCorps™ Experience in Canyon Country, Utah | Jessica Uglesich

A guest blog post for the Geological Society of America by a BLM intern describing her experience with developing public outreach and education. Jessica also decribes her work with recovering bones from a looted site and work with the local Dystrophaeus project (@Dystrophaeus).

Major bonebeds in mudrocks of the Morrison Formation (Upper Jurassic), northern Colorado Plateau of Utah and Colorado | Geology of the Intermountain West

Download PDF field guide by John Foster et. al. The Morrison Formation contains a number of large quarries that have yielded dinosaurs and other vertebrates, and many of these occur in sandstone beds representing ancient river channels. However, a number of very productive sites occur in mudstone beds representing other environments such as ephemeral ponds, and some of these yield both large dinosaurs and microvertebrates; these localities in mudstone beds represent different taphonomic modes of preservation and often preserve vertebrate taxa in different relative abundances from the channel sandstone sites. Among these important and very productive mudstone localities are the Cleveland-Lloyd Quarry, the Mygatt-Moore Quarry, and the microvertebrate sites of the Fruita Paleontological Area, and each of these preserves distinct vertebrate paleofaunas, different from sandstone sites and from each other, suggesting that mudstone localities had a very different mode of sampling the local biotas than did sites in sandstone.

Tracking dinosaurs in BLM canyon country, Utah | Geology of the Intermountain West

Download PDF copy of the field guide by Rebecca Hunt-Foster et. al. The remarkably extensive and abundant Mesozoic-aged exposures on public lands around Moab have made this region well known for ichnofossils. The nearly complete record of Upper Triassic through Lower Cretaceous rocks exposed in this area is well known for its sheer abundance of tracks and traces. This three-day field trip will visit many important classic and new sites exposed in the Bureau of Land Management’s Canyon Country District. This field trip guidebook will give one an overview of the major sites we will visit, as well as a brief summary of work previously done in these areas.
