thought. so why is that significant? we used to think that pterosaur is were pretty small for the first several tens of millions of years of the revolution, that they never really got bigger than about four or five metre wingspan is, give or take and later in the cretaceous period, the end of the age of the dinosaurs, the end of the age of the dinosaurs, the time of the t rex, you got dinosaurs that were as big as fighterjets. now we have this jurassic age fossil and we are seeing a big pterosaur at about 170 million years ago, as big as the biggest flying birds today so pterosaur is had evolved that size and when this animal was soaring over the heads of dinosaurs in the lagoons of the ancient isle of skye during thejurassic period, it was the biggest thing that we know of that had ever flown in the entire history of the world. and this is just a superlative scottish fossil, nothing like this has been found
