The Pterosaur also had a small crest on the top of its head which was probably used in mating rituals as well as to stabilize it during flight. What makes this species interesting, apart from its bizarre anatomical endowments, is that it provides a tantalizing glimpse into the global distribution of pterosaurs and their lifestyle. Most pterosaur fossils have been found in areas which were once river valleys or arid plains, suggesting that they dwelt mainly inland and that only the larger species were built for overseas travel.
This fossil was found in marine sediments, adding another ecological system to the world of the pterosaur. Secondly, the closest living relative of Guidraco is a Brazilian species called Ludodactylus sibbicki. 120 million years ago, the landmasses which would become South America and China were on opposite sides of the Earth, separated to the east by a land ruled by dinosaurs and to the west the young Pacific ocean, ruled by giant marine predators.
Yet the similarity between the two species shows that some pterosaurs or pterosaur groups had a global range. The palaeontologists predict that this will become more apparent with more fossil discoveries around the world,' said Eberhard “Dino” Frey, a paleontologist at the State Museum of Natural History in Karlsruhe. 'It’s only a matter of time before more pterosaurs pop out of the rock. I don’t think we are at the end of the findings, we’re going to see more and more overlaps and discover only a few species were endemic to a region'
