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.
Ptychadena trinodis
"Ptychadena trinodis" is a relatively large frog with a pointed head. Males measure and females in snout–vent length. Males have paired lateral vocal sacs. The tympanum is large and distinct. There are three pairs of continuous dorsal ridges that start at the level of the eyes, and a shorter, median pair. The hind legs are sturdy and of moderate length. The inner metatarsal tubercle is massive, almost as long as the shortest toe. The colouration is generally brownish or grayish, with black or dark brown spots present on dorsal ridges, flanks, and the dorsum.
