Audi introduced its concept car Audi AI: Trail at the IAA 2019. The car is special because it combines futuristic design with autonomous driving, electric mobility.
Scientists have discovered on Antarctica a fossil of a tail bone belonging to a titanosaur, the family of giant plant-eating dinosaurs. Titanosaurs were sauropods, four-legged herbivorous dinosaurs with long necks and tails. Their remains have been found around the world but this is the first evidence they may have wandering Antarctica. The new specimen was discovered on James Ross Island by an Argentinian-led team. Scientists identified it as belonging to a “lithostrotian titanosaur” from the Late Cretaceous period around 70 million years ago. It consists of section of vertebrae almost 20cm long believed to have come from the middle third of the dinosaur’s tail.
As reported German journal Naturwissenschaften according to Authors Dr Ignacio Alejandro Cerda, from the Conicet research institute in Argentina, and colleagues thier finding indicates that advanced titanosaurs achieved a global distribution at least by the Late Cretaceous. Titanosaurs included the mighty Argentinosaurus, which may have reached 100ft (30 metres) in length. However the discovery of a single vertebrae fossil yielded too little information to allow speculation about the dinosaur’s species.
