These “lizard feet” had five-toed feet, like lizards, but had little else in common with them. Among the largest beasts that ever walked the earth, these peaceful plant-eaters included giants the length of several buses, and heavier than perhaps a dozen big bull elephants. By Late Jurassic times, sauropods ranked among the most abundant of all plant-eating dinosaurs in lands as far apart as western North America, East Africa, and China.

A “lizard-bird robber” from Late Cretaceous southern Alberta, Canada. It was named by Canadian paleontologist Hans-Dieter Sues in 1978.

A “bird-like lizard” from Late Cretaceous Mongolia. It was named by paleontologist Henry Fairfield Osborn in 1924.

The "dinosaur crocodile" named in reference to the resemblance of the animal's huge skull to that of a carnivorous saurischian dinosaur. From Late Triassic South America. Named by Reig in 1959.

Known as Scomberesocidae, or skippers, they are typically active zooplankton feeders that commonly skip and jump at the surface in large schools.

A “Scania lizard” from Late Cretaceous Northern Europe. This fossil was named to indicate a form found in the province of Scania, in the Baltic region of southern Sweden. Named by Persson in 1959.

A “limb (or rib or hind-leg) lizard” from Early Jurassic Lyme Regis, southern England, Arizona (USA), and Tibet. It was named by British anatomist Sir Richard Owen in 1868.

This nomenclature (“spiny lizard”) is no longer recognized by scientists because they found that it described an animal that was previously given another name which is Eoplocephalus or Dyoploaurus. Named by Franz Baron Nopcsa in 1928.

A “small (little)-shield lizard” from Late Jurassic Arizona (southwestern USA). Named by Edwin Harris Colbert (born 1905) in 1981.

A “separate (or severed, divided) lizard” from Late Cretaceous Argentina. It was found in Patagonia, Argentina, and therefore, it is said to be a fossil-form that is geographically separated from the North American, European, and Asian members of the family. Named by Michael K. Brett-Surman in 1979.

“Seeley lizard” Early Jurassic Europe. Named in honor of Harry Govier Seeley (1839-1909), British vertebrate paleontologist. Named by White in 1940.

“Segi Canyon lizard” may be from Early Jurassic period and found in Segi Canyon (Navajo Sandstone), north-central Arizona. Named by Charles Lewis Camp in 1936.

A family of “slow lizards”.

A “slow lizard” from Late Cretaceous southeast Mongolia. Named by Altangerel Perle in 1979.
