Late Jurassic
Morrison Formation, Colorado
ITEM# JEWERLY-Colorado-0001
Beautifully cut and polished dinosaur bone bracelet made from bone acquired on private land from the Morrison Formation, Colorado.
The Morrison Formation is a distinctive sequence of Late Jurassic sedimentary rock that is found in the western United States, which has been the most fertile source of dinosaur fossils in North America. It is composed of mudstone, sandstone, siltstone, and limestone and is light grey, greenish gray, or red. Most of the fossils occur in the green siltstone beds and lower sandstones, relics of the rivers and floodplains of the Jurassic period.
It is centered in Wyoming and Colorado, with outcrops in Montana, North Dakota, South Dakota, Nebraska, Kansas, the panhandles of Oklahoma and Texas, New Mexico, Arizona, Utah, and Idaho. Equivalent rocks under different names are found in Canada. It covers an area of 1.5 million square km (600,000 square miles), although only a tiny fraction is exposed and accessible to paleontologists and geologists Over 75% is still buried under the prairie to the east, and much of its western paleogoegraphic extent was eroded during exhumation of the Rocky Mountains.
It was named after Morrison, Colorado, where the first fossils in the formation were discovered by Arthur Lakes in 1877 at the type locality (the location that defines the formation) at Dinosaur Ridge, west of Denver, Colorado. In Colorado, New Mexico, and Utah, the Morrison Formation was a major source of uranium ore.
Though many of the Morrison Formation fossils are fragmentary, they are sufficient to provide a good picture of the flora and fauna in the Morrison Basin during the Kimmeridgian. Overall, the climate was dry, similar to a savanna but, since there were no flowering plants (angiosperms-grasses, flowers, and some trees), the flora was quite different. Conifers, the dominant plants of the time, were to be found with ginkgos, cycads, tree ferns, and horsetail rushes. Much of the fossilized vegetation was riparian, living along the river flood plains. Insects were very similar to modern species, with termites building 30 m (100 ft.) tall nests. Along the rivers, there were fish, frogs, salamanders, lizards, crocodiles, turtles, pterosaurs, crayfish, clams and monotreme mammals, the largest of which was about the size of a rat.
These bracelets have a large amount of both fossilized bone and sterling silver, and are rather heavy.
