![]() “Never before has so much detailed information on azhdarchids (the pterosaur family that includes Quetzalcoatlus) been gathered in the same place, this meaning that the work will serve as the standard go-to study of this group for years – probably decades – to come,” concluded vertebrate paleontologist Darren Naish.īy Andrei Ionescu, Earth. With a wingspan nearing 40 feet, the giant pterosaur Quetzalcoatlus is the largest known animal to take to the sky. While the larger Quetzalcoatlus might have lived like today’s herons, hunting alone in rivers and streams, the smaller species appeared to flock together in lakes with at least 30 individuals found at a single fossil site. The researchers also found more details about these dinosaurs’ possible habitats and behaviors. “Pterosaurs have huge breast bones, which is where the flight muscles attach, so there is no doubt that they were terrific flyers,” said collection co-editor Kevin Padian, an emeritus professor and emeritus curator at the University of California, Berkeley.Īlthough scientists previously assumed that the pterosaur rocked forward on its wingtips like a vampire bat, or built up speed by running and flapping like an albatross, these new analyses suggest that it may have initially jumped at least eight feet into the air before lifting off by flipping its wings. Later on, they applied their insights to its larger cousin too. This offered the scientists the possibility to reconstruct an almost complete skeleton and study the ways in which it moved and flew. quetzalcoatlus a giant flying pterosaur with a 36 feet wide wingspan from the late creataceous period, soaring on thermals above what is now the state of texas. While the larger species is known from only around a dozen bones, hundreds of fossils from the smaller species were discovered. Last thing I remember on the big Azhdarchids since Witton and Habib was the monograph on Quetz, which I kinda hate because Padian kinda hijacked it to push his unorthodox-if-not-fringe theories on their membranes and launch postures, which, of the multiple authors, only he promotes.The in-depth study of all confirmed and suspected Quetzalcoatlus bones led to the identification of two new pterosaur species, including a smaller one, with an 18-to-20-foot wingspan, which was named Quetzalcoatlus lawsoni, in the honor of Douglas Lawson, the geologist who discovered the bones in 1971. That relatively pointless rant aside I'm not sure if I'm missing some big paper recently because I've not been watching as closely as I once did. Quetzalcoatlus was one of the largest animals ever to fly: its wingspan has been. I hate to focus on this especially considering this is the internet and English might just not be your first language in which case this is just something this language does sometimes that sucks, but you're kind of insisting a non-technical term has a very particular technical definition- if you were saying mass is the BEST measure of an organism's size, as it gets around bauplans that can "cheat" (giraffes, siphonophores, pterosaurs themselves), I would be inclined to agree, but then that would mean that a Holstein cow is like three times the "size" of both Quetz and Hatz and that's why being specific about the type of size is important. Quetzalcoatlus was a pterosaur from the pterodactyl group that lived in. ![]() Size and Big are not specific dimensional terms, and can refer to any linear, area, volumetric, or mass dimension equally well, as well as quantities and so on. By the dimension of length specifically, the size of Spinosaurus exceeds Tyrannosaurus (unless that changes too, at this rate I wouldn't doubt that).
