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.
4147 Lennon
According to the survey carried out by NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, "Lennon" measures 5.2 and 7.1 kilometers in diameter and its surface has an albedo of 0.24 of 0.42, respectively. The "Collaborative Asteroid Lightcurve Link" assumes an standard albedo for S-type asteroids of 0.20 and calculates a diameter of 7.5 kilometers with an absolute magnitude of 13.0. The discrepancy is due to disagreement on the body's spectral type (V or S).
