INDIANA JONES - Interestingly enough, I actually read a recent bit of paleontological information that suggests the term "pterodactyl" has its strongest roots within older television shows and movies, such as the Flintstones, the Land that Time Forgot, Journey to the Center of the Earth and the Lost World (not that which is related to the Jurassic Park series). Much like what CARNOSAUR has been so kind to illustrate, it would appear that the name Pterodactylus was shortened to Pterodactyl because it was phonetically "awkward".
As for my favorite pterosaur, I believe I must second CARNOSAUR'S nomination for Ornithocheirus! That was one marvelous and incredibly massive pterosaur! I can only imagine what such a creature would have looked like on the wing! :)
