Question: What is the sentiment of the following document towards the entity Alexander Kellner ? Pterosaurs ran the gamut from the gigantic  aircraftlike Quetzalcoatlus all the way down to animals about the size of a sparrow  such as Nemicolopterus. Some had the long  pointy snouts we typically associate with the flying reptiles. Others boasted wild and crazy crests  which may have been used to attract the opposite sex  as has been suggested with H. tianshanensis. And still other pterosaur species had short  squat skulls more like  that of a frog   Chiappe said. (Albeit  a very scary frog.)
