Pteranodon
Pteranodon (; from Greek πτερόν ( pteron, "wing") and ἀνόδων (anodon, "toothless") is a genus of pterosaur that included some of the largest known flying reptiles, with wingspans over 8 meters (26 feet). They lived during the late Cretaceous geological period of North America in present-day Kansas, Alabama, Nebraska, Wyoming, and South Dakota. More fossil specimens of "Pteranodon" have been found than any other pterosaur, with about 1,200 specimens known to science, many of them well preserved with nearly complete skulls and articulated skeletons. It was an important part of the animal community in the Western Interior Seaway.
9951 Tyrannosaurus
This minor planet was named for Tyrannosaurus, a large and heavy bipedal carnivorous dinosaur, that lived in the upper cretaceous. It was one of the most terrifying predators, with a large skull, massive jaws and sharp teeth. Adult individuals were 12 meters long and 4–7 meters high. Tyrannosaurus rex is the best known species of this genus. The official naming citation was published by the Minor Planet Center on 20 November 2002 ().
