Pterodactylus (from Ancient Greek: πτεροδάκτυλος, romanized: pterodáktylos ' winged finger ' [2]) is a genus of extinct pterosaurs.It is thought to contain only a single species, Pterodactylus antiquus, which was the first pterosaur to be named and identified as a flying reptile and one of the first prehistoric reptiles to ever be discovered.
Some species of pterosaurs grew to very large sizes and this has implications for their capacity for flight. Many pterosaurs were small but the largest had wingspans which exceeded 9 m (30 ft). The largest of these are estimated to have weighed 250 kilograms (550 lb).
Pterosaurs – commonly known as pterodactyls – lived some 225 million years ago, and thrived for more than 100 million years before perishing with the dinosaurs in the extinction at the end of ...
Size of Istiodactylus latidens compared to a human Ornithocheiromorphs were large pterosaurs, with wingspans normally ranging between 3 and 6 meters (9.8 and 19.7 ft). [ 3 ]
Pterodactyloidea (derived from the Greek words πτερόν (pterón, for usual ptéryx) "wing", and δάκτυλος (dáktylos) "finger") [2] is one of the two traditional suborders of pterosaurs ("wing lizards"), and contains the most derived members of this group of flying reptiles.
The position of the eyes of tyrannosaurids suggests that they had a very well developed sense of vision. Combined with the shape of the head they had better binocular vision than allosauroids. The eye position of Tyrannosaurus rex was similar to that of modern humans, but their eyes and optic lobe were much larger than that of modern humans.
Pterodactyls also don't have any descendants and had very fragile bones, making it hard for scientists to determine facts about them. #16 Image credits: ralph_the_rex
