A “pirate lizard” from Late Cretaceous North America. Named by Joseph Leidy in 1865.

“Pisano’s lizard” from Late Triassic northwest Argentina. Named in honor of Juan A. Pisano, an Argentine paleontologist at the faculty of Natural Sciences and the Museum of La Plata, Argentina. Named by R. M. Casamiquela in 1967.

A reptile with flipper-like limbs that amphibious. Fossils were found in France and Germany where it lived during the Middle Triassic period. It is not considered to be a dinosaur.

“Piveteau’s lizard” from Middle Jurassic Normandy, France. It was named in honor of Jean Piveteau (1899-1991), a French paleontologist. Named by Philippe Tauqet and U. S. paleontologist Samuel Paul Welles in 1977.

Its name “flat lizards” which were built like anchisaurids, but most were larger, with bigger, stronger skulls, jaws hinged in a more effective way, and broader hands and feet. They lived from Late Triassic to Early Jurassic times in the Americas, Europe, Africa, and Asia.

A “flat (or broad) lizard” from Late Triassic Germany, France, Switzerland, England, Nova Scotia (Canada) and South Africa. This fossil was formerly called Dimodosaurus, Gresslyosaurus, Pachysauriscus, Pachysaurus, and Sellosaurus. Named by naturalist naturalist Hermann von Meyer in 1837.

A “near” (“approximate to the Saurians”) from Early Jurassic Europe (England and Germany). It was not a dinosaur. Named by De la Beche and William Daniel Conybeare in 1821.

A “more (greater) saurian”) from Middle-Late Jurassic and Creataceous Europe. It was not a dinosaur. Named by British anatomist Sir Richard Owen in 1841.

"Sea Rex Pliosaurs" apparently were as big as buses with teeth the size of bananas.

• They probably lay in wait and lunged at their prey.
• They lived in the Jurassic period but were marine reptiles, and again, not dinosaurs.
• The largest known pliosaur fossil, a 50-foot-long, 150-million-year-old specimen was found by University of Oslo researchers.
• It was found in a hillside of shale on the high Arctic island of Spitsbergen, 400 miles from Norway's coast.

A “floating lizard” from Late Cretaceous North America was not a dinosaur. It was a marine reptile that swam in shallow seas.

Identified as being a “swift-footed lizard” from Early Jurassic North America a small carnivorous dinosaur and was considered to be one of the earliest known dinosaurs to inhabit the eastern United States.

This nomenclature (Podokesaurus, “swift-footed lizard”) is no longer recognized by scientists because they found that it described an animal that was previously given another name which is Coelophysis; named by US paleontologist Mignon Talbot in 1911.

This nomenclature (“many-toothed lizard”) is no longer recognized by scientists because they found that it described an animal that was previously given another name which is Stenonychosaurus. Named by U. S. paleontologist Charles Whitney Gilmore in 1932.

Means “Popo Agie lizard” from Late Triassic Wyoming. Its name comes from Crow Indian popo agie, “head (water) river”. It was named for the Popo Agie River, in the Triassic red beds near Lander, Wyoming, by Professor E. B. Branson. Named by M. G. Mehl in 1915.

Means “before-the-Bactrian lizard” from Early Cretaceous China and Mongolia. Named by Anatoly Konstantinovich Rozhdestvensky in 1966.

Means “before-the-horned lizard” or “before Ceratosaurus” from Early Jurassic England (Bathonian Great Oolite of Gloucestershire). Named by German paleontologist Friedrich von Huene in 1926.

This nomenclature (“before-tailed lizard”) is no longer recognized by scientists because they found that it described an animal that was previously given another name which is Iguanodon. Named by German paleontologist Friedrich von Huene in 1902.
