With the release of Jurassic World, IBTimes UK looks at the five biggest dinosaurs ever to have walked the planet.
5. In fifth place is Turiasaurus – the largest dinosaur ever to be found in modern-day Europe. It is known from a single fossil specimen discovered in Spain in 2006. The sauropod lived 140 million years ago. It measured around 100ft and weighed between 40 and 80 tonnes.
4. Tipping the scales at number four is Brachiosaurus, first discovered in 1903. This herbivorous dinosaur lived between 155 and 140 million years ago in the Late Jurassic period and likely fed off leaves from the tallest trees. Although sizes differ from fossil to fossil, scientists think Brachiosaurus was about 82ft long and weighed in at 60 tonnes, although estimates vary.
3. Taking the third spot is Paralititan, meaning 'tidal giant'. This beast lived in the Late Cretaceous Period between 99 and 94 million years ago. It was first discovered in coastal deposits in the Upper Cretaceous Bahariya Formation of Egypt. While its size is difficult to estimate, it is thought it was over 90ft in length and weighed anywhere between 60 and 70 tonnes.
2. In second place is Dreadnoughtus, a herbivorous dinosaur that roamed the earth 77 million years ago. Scientists discovered a complete skeleton of the supermassive sauropod dino in Argentina. It was 85ft long and weighed around 65 tonnes – the equivalent of seven T.Rexes or a dozen African elephants.
1. The current record holder for the largest land animal ever found is the mighty Argentinosaurus. It evolved during the Cretaceous Period – about 90 million years ago – and lived on the ancient supercontinent Gondwana. It weighed in at up to around 100 tonnes and was about 115m in length.
