Fossilized dinosaur brain tissue identified for the first time
2016-10-27 12:00:00| LifeSciencesWorld
[NEWS] An unassuming brown pebble, found more than a decade ago by a fossil hunter in Sussex, has been confirmed as the first example of fossilised brain tissue from a dinosaur. The fossil, most likely from a species closely related to Iguanodon, displays distinct similarities to the brains of modern-day crocodiles and birds. Meninges - the tough tissues surrounding the actual brain - as well as tiny capillaries and portions of adjacent cortical tissues have been preserv…

New study finds evidence for a 'fast' dinosaur extinction
2016-06-15 12:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Guardian: Boring is beautiful when youre studying a calamity, especially one as spectacular as the mass extinction that wiped out the dinosaurs. Thats because exciting sediments, full of variations and gaps, make it hard to disentangle the extinction signal from the noise of natural variability. So you could say that James Witts, of the University of Leeds in the UK, lucked-out with an especially boring batch of sediments in Seymour Island on the Antarctic Peninsula (the part on the map that points up...

Dinosaur Extinction Event Took Out Polar Creatures, Too
2016-05-27 22:23:00| Climate Ark Climate Change & Global Warming Newsfeed
United Press International: Whether caused by asteroid or volcanism -- or both -- scientists now know few places on Earth offered safety from the extinction event that killed the dinosaurs. An extensive survey of ancient marine fossils from the Antarctic Peninsula proves the ecosystems to the south suffered considerably during the Cretaceous-Paleogene extinction event. The survey included 6,000 marine fossils dated to between 69 million and 65 million years old. A wide range of species and sizes were included -- from sea...
