Charles Robert Knight (October 21, 1874 – April 15, 1953) was an American wildlife and paleoartist best known for his detailed paintings of dinosaurs and other prehistoric animals. His works have been reproduced in many books and are currently on display at several major museums in the United States .
La Brea Tar Pits fauna as depicted by Charles R. Knight A list of prehistoric and extinct species whose fossils have been found in the La Brea Tar Pits , located in present-day Hancock Park , a city park on the Miracle Mile section of the Mid-Wilshire district in Los Angeles , California .
Paleoartist Charles R. Knight, the first to depict dinosaurs as active animals, dominated the paleoart landscape through the early 1900s. The modern era of paleoart was brought first by the " dinosaur renaissance ", a minor scientific revolution beginning in the early 1970s in which dinosaurs came to be understood as active, alert creatures ...
[23] [40] Osborn (1899) included a life impression of AMNH FR 221 by paleoartist Charles R. Knight. [39] The restoration carried a number of erroneous features, such as a baggy throat, bloated belly, and inaccurate paddles and dorsal fin. [41] But a seminal feature was the addition of a dorsal crest (known as a fringe) lining the mosasaur's back.
Tylosaurus was the third new genus of mosasaur to be described from North America behind Clidastes and Platecarpus and the first in Kansas. [13] The early history of the genus as a taxon was subject to complications spurred by the infamous rivalry between American paleontologists Edward Drinker Cope and Othniel Charles Marsh during the Bone Wars.
Instead, they primarily relied on stratigraphic associations and Cuvier's 1808 research on the holotype skull. Thus, in-depth research on the placement of Mosasaurus was not undertaken until the discovery of more complete mosasaur fossils during the late 19th century, which reignited research on the placement of mosasaurs among squamates.

From roughly 230-200 million years ago, during the Late Triassic and into the early Jurassic periods, dinosaurs emerged from just one of many reptilian species to become the dominant species on Earth.
Mosasauroidea is a superfamily of extinct marine lizards that existed during the Late Cretaceous.Basal members of this group consist of small semiaquatic forms with terrestrial limbs ("plesiopedal"), while laters members include larger fully aquatic paddle-limbed ("hydropedal") forms commonly known as mosasaurs.
