The genus was erected by David Starr Jordan in 1907, in honor of the late University of Wyoming professor Wilbur Clinton Knight, "an indefatigable student of the paleontology of the Rocky Mountains."

Dunkleosteus. Dunkleosteus is an extinct genus of large arthrodire ("jointed-neck") fish that existed during the Late Devonian period, about 382–358 million years ago. It was a pelagic fish inhabiting open waters, and one of the first apex predators of any ecosystem. [1]
The fossils include unique species of fish that had never been found in the area before. The discovery is reshaping views on California geology with the possibility of extinct islands.
Folsom site. Folsom site or Wild Horse Arroyo, designated by the Smithsonian trinomial 29CX1, is a major archaeological site about 8 miles (13 km) west of Folsom, New Mexico. It is the type site for the Folsom tradition, a Paleo-Indian cultural sequence dating to between 11000 BC and 10000 BC. The Folsom site was excavated in 1926 and found to ...
March 30, 1973. The Calico Early Man Site is an archaeological site in an ancient Pleistocene lake located near Barstow in San Bernardino County in the central Mojave Desert of Southern California. This site is on and in late middle- Pleistocene fanglomerates (now-cemented alluvial debris flow deposits) known variously as the Calico Hills, the ...
Paleontology in California refers to paleontologist research occurring within or conducted by people from the U.S. state of California. California contains rocks of almost every age from the Precambrian to the Recent. During the early Paleozoic, California was covered by a warm shallow sea inhabited by marine invertebrates such as ammonites ...
The evolution of fish began about 530 million years ago during the Cambrian explosion. It was during this time that the early chordates developed the skull and the vertebral column, leading to the first craniates and vertebrates. The first fish lineages belong to the Agnatha, or jawless fish. Early examples include Haikouichthys.
