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.
Metopes of the Parthenon
The Parthenon was erected between 447 and 438 BC. The "pre-Parthenon" (little known) was hexastyle. Its successor, which was much larger, was octastyle (eight columns in front and seventeen on the sides of the peristyle) and measured 30.88 meters wide and 69.50 meters long. The sekos (closed part surrounded by the peristyle) in itself had a width of 19 meters. Thus, two large rooms could be created: one, to the east, to accommodate the statue of a dozen meters high; the other, to the west, to shelter the treasure of the league of Delos. The construction site was entrusted to Ictinos, Callicrates and Phidias The decor project was both traditional in its form (pediments and metopes) albeit unprecedented in scale. The pediments were bigger and more complex than what had been done before. The number of metopes (92), all carved, was unprecedented and never repeated. Finally, while the temple was of the Doric order, the decoration around the sekos (normally composed of metopes and triglyphs ) was replaced by a frieze of the ionic order.
