The newly described pterosaur with a wingspan over 30-feet was one of the largest flying creatures to ever exist.
The species, described in a new study, is actually not all that new. It was dug up in Dinosaur Provincial Park in 1992, and its skeletal remains were kept at the Royal Tyrrell Museum. Back then, however, paleontologists assumed it was a specimen of an azhdarchid pterosaur with a 32-foot wingspan called Quetzalcoatlus northropi. First dug up in Texas in 1972, Quetzalcoatlus was the largest flying animal to ever live.
As Michael Greshko at National Geographic reports, the specimen from the Royal Tyrrell had a wingspan of about 16 feet and was likely a juvenile, but another incomplete bone at the museum that is believed to be from the same species shows that it reached mammoth proportions, with a wingspan of more than 30 feet, 8-foot-tall shoulders when standing on ground and an estimated weight of 550 pounds.
