Biggest pterosaur ever found was as tall as a giraffe

A remarkableflying reptile that was as tall as a giraffe, weighed half a tonneand had a longer wingspan thana Cessna Skyhawk plane has been put on display at a museum in Germany.

The bones of the powerful pterosaur, an ancient flying reptile closely related to dinosaurs,are now on display at theAltmuehltalDinosaur Museum in Germany as part of its Emperors of the Skiesexhibit. The museum saidit's the "largest and most robust" pterodactyl ever found.

In a news release,paleontologists who excavated and studied the creature reported that it would have likely had a mass of more than half a tonne and would have stood as tall as a giraffe. Itswingspan was more than 12 metres and possibly up to 20 metres. A Cessna Skyhawkfour-seater plane has a wingspan of 11 metres.

The pterosaur was also very powerfully built, with a neck as wide as a full-grown man and a wrist bone bigger than that of a mammoth, said Matyas Vremir, the paleontologist who discovered the first bone of the fossil, in a statement.

The pterosaur has been nicknamed Dracula because it wasfound in an 120-metre high cliffin Transylvania in Romania in 2009. The cliff would have been part of a subtropical island at the time the pterosaur lived, during the Cretaceous period leading up to the extinction of dinosaurs 66 million years ago.

Paleontologists working on the project say they initially didn't believe the creature was what it turned out to be.

"Facing this gigantic neck vertebra, we couldn't identify it, you know," said Raimund Albersdorfer, a paleontologist at theAltmuehltalDinosaur Museum. Eventually, they realized it must be a pterosaur "a gigantic, unique pterosaur and we just freaked out."

Albersdorfer said his teamhad to rappel downa steep slope and hammer into the rock 80 metres above the base of the cliff to excavate the fossil.
