when did the second species you mentioned live?
hey existed during most of the Mesozoic: from the late Triassic to the end of the Cretaceous (228 to 66 million years ago).
Pterosaur
Pterosaurs (; from Greek "pteron" and "sauros", meaning "wing lizard") were flying reptiles of the extinct clade or order Pterosauria. They existed during most of the Mesozoic: from the late Triassic to the end of the Cretaceous (228 to 66 million years ago). Pterosaurs are the earliest vertebrates known to have evolved powered flight. Their wings were formed by a membrane of skin, muscle, and other tissues stretching from the ankles to a dramatically lengthened fourth finger.
where is the cliturous located on a woman It is at the front junction of the labia minora (inner lips), above the opening of the urethra what is the function of this organ? It acts as a primary anatomical source of human female sexual pleasure. and what is the biological process through which this is achieved? Through sexual reproduction is it present in the female species of all animals? It is present in mammals, ostriches and a limited number of other animals. who identified it for the first time? UNANSWERABLE what are the distinguishing features of the class of animals you just mentioned? They are a group of vertebrate animals constituting the class Mammalia (), and characterized by the presence of mammary glands which in females produce milk for feeding (nursing) their young, a neocortex (a region of the brain), fur or hair, and three middle ear bones. can you name some of the first species of this class who lived on planet earth? It included crocodylomorphs, the pterosaurs ,the dinosaurs and arge cynodonts like "Trucidocynodon" and traversodontids

Pterosaur [SEP] Introduction
In life, pterosaurs would have had smooth or fluffy coats that did not resemble bird feathers. They were warm-blooded (endothermic) active animals. The respiratory system had efficient unidirectional "flow-through" breathing using air sacs, which hollowed out their bones to an extreme extent. Pterosaurs spanned a wide range of adult sizes, from the very small anurognathids to the largest known flying creatures of all time, including "Quetzalcoatlus" and "Hatzegopteryx", which reached wingspans of at least nine metres. The combination of endothermy, a good oxygen supply and strong muscles made pterosaurs powerful and capable flyers.
