This work started 10 years ago, when the first dates using the OSL method were obtained. It is then that the first traces of footprints left by vertebrates were found. In subsequent years the successive natural collapse of sand has revealed further material and has permitted a detailed study including new dates.
A new dinosaur that wears its ‘heart’ on its tail provides new clues to how ecosystems evolved on the African continent during the Cretaceous period.
Scientists have discovered the fossils of an iguana-sized reptile, which they named ‘Antarctic king,’ that lived at the South Pole 250 million years ago (it used to be warmer). Antarctanax was an early cousin of the dinosaurs, and it shows how life bounced back after the world’s biggest mass extinction.
“It’s great to see the number of people present here today,” said one march organizer. “It’s an incredible signal. This cannot be ignored.”
An international team of palaeontologists has discovered that the flying reptiles, pterosaurs, actually had four kinds of feathers, and these are shared with dinosaurs — pushing back the origin of feathers by some 70 million years.
More than 85 well-preserved dinosaur footprints — made by at least seven different species — have been uncovered in East Sussex, representing the most diverse and detailed collection of these trace fossils from the Cretaceous Period found in the UK to date.
Sixty-six million years ago, an asteroid hit the Yucatan Peninsula in Mexico and produced cataclysmic disruptions that, it is believed, killed off about 75% of species (the K/Pg extinction). But many researchers think there must have been other factors at work.
