The very name ‘Pterosaur’ comes from the Greek for ‘winged lizards’. These astounding flying reptiles ruled the skies between the late Triassic to the end of the Cretaceous Period; and quite unsurprisingly, one of the largest known flying animals of all time – Quetzalcoatlus, comes from this extinct clade. In terms of size, the larger variant of Quetzalcoatlus’ is estimated to have had an incredible wingspan of over 36 ft. But interestingly this was just one end of the size spectrum, with some Pterosaur specimens also showcasing the diminutive dimensions of small sparrows.
