Fruita, Colorado Riggs and crew found nearly two thirds of an "Apatosaurus excelsus" skeleton (commonly known as a Brontosaurus) on the northeast side of Dinosaur Hill, in Fruita. This is still considered to be one of the finest specimens known. Later, other sauropod bones were also found, which eventually led to the landmark's name. The animals were from the late Jurassic Age (150 million years ago) and within the Morrison Formation. Fossils of the "Fruitadens" (a heterodontosaurid dinosaur), the world's smallest known plant-eating dinosaur, were first found in the Fruita Paleontological Area (within the McInnis Canyons National Conservation Area) off Kings View
Total known weight found, the "total known mass" could, in principle, rise. However, this is complicated by the method by which meteorites are named. Historically (before the 1970s), every meteorite was given a simple geographical name. The total number of known meteorites was small and it was generally a simple matter to determine when a newly found fragment was "paired" to a previously discovered meteorite. When pairing could be established, the new fragment would not be given a new name, and the "total known mass" of the original meteorite would increase. But, recent discoveries of arid regions containing large concentrations of meteorites have
