A “fisher lizard” from Late Cretaceous North America. Its name comes from Greek hydrotheras, “fisherman”. It was found in the Maastrichtian Moreno Formation, Panoche Hills, Fresno County, California. Named by U. S. paleontologist Samuel Paul Welles in 1943.

A “woodland (Wealden) lizard” from Late (or Early) Cretaceous southeast England. It was named for the lower Cretaceous Wealden deposit at Tilgate Forest. In an 1832 presentation before the Geological Society, Mantell originally explained the name as “forest lizard”, alluding to Tilgate Forest where the first specimen was unearthed; however, in later published works he gave the meaning as “Wealden lizard”, establishing the use of hylaeo- as a kind of pun in 19th century paleontology for the geological term “Wealden” (Hylaeochampsa Owen “Wealden crocodile”, Hylaeochelys Lydekker “Wealden turtle”,etc.). The British geologist, Peter Martin, invented the name “Wealden” in 1828 for the Early Cretaceous sands and clays found in the once-forested Weald (“wood”) region of southern England. This creature was previously known as Polacanthus. Named by British paleontologist Gideon A. Matheron Mantell (1790-1852) in 1833.

Means “under (below) the top lizard” or “very high lizard” or “near-topmost lizard” from Late Cretaceous Alberta and Montana. Formerly known as Cheneosaurus. Named by paleontologist Barnum Brown (1873-1963) in 1913.

A “high-ridge lizard” from Late Cretaceous southern and central France and Spain. Its name is based on Greek hypselos, “high, lofty”. Named by Pierre-Emile-Philippe Matheron in 1869.

An extinct fishlike marine reptile of the order Ichthyosauria of the Triassic to the Cretaceous periods.

A “fish reptile” which was a dolphin-like reptile believed to have been in what is now England, Germany, Greenland, and Alberta, Canada during the Early Jurassic to the early Cretaceous periods. It was not a dinosaur but another type of extinct reptile.

“Indian lizard” from Late Cretaceous central (Jabalpur) India. Named by paleontologists Friedrick von Huene and Charles Matley in 1933.

Means “in Tedreft lizard” from Late Cretaceous period and found in Tedreft and In Abangarit, Niger. Named by French paleontologist Albert F. de Lapparent in 1960.

“Ischigualasco lizard” from Late Triassic Ischigualasco Valley and Triassic rock formations of northwest Argentina. This name is now known as Herrerasaurus. Named by Osvaldo A. Sauvage Reig in 1963.

This nomenclature (“strong lizard”) is no longer recognized by scientists because they found that it described an animal that was previously given another name which is Pelorosaurus. Named by British paleontologist Richard Lydekker in 1888, but he attributes the name to J. W. Hulke in 1874.

Found in India, it was a titanosaurid dinosaur that is believed to have lived during the Late Cretaceous period. Named by Adrian Paul Hunt, Martin G. Lockley, Frederic Augustus Lucas (1852-1929), and Meyer in 1995.

A “Jaxartes-leg lizard” from Late Cretaceous Kazakhstan. Named by Anatoly Nicolaevich Riabinin in 1937.

The “Kai River lizard” from Middle Jurassic China. Named by Chinese paleontologist He Xinlu in 1984.

The “Kangna’s lizard” is the name given to a tooth and leg bone found in Early Cretaceous rocks of Little Namaqualand, South Africa. Named by paleontologist Haughton in 1915.

An early reptile, not a dinosaur, that lived during the Triassic period. Fossils were found in Guanglin, Guizhou Province, China. Named by Chung Chien Young in 1958.
