Sent in by William – fossil of a huge raptor dinosaur unearthed in Patagonia – see https://www.yahoo.com/news/argentine-scientists-discover-fossil-largest-225706758.html … and https://www.yahoo.com/news/shadow-death-dinosaur-fossils-discovered-145318966.html … and again, https://www.yahoo.com/news/fossils-giant-marine-reptiles-found-161604250.html … and in the case of the latter one, fossils of ichthyosaurs have been found on top of three mountains in the Swiss Alps, 8990 feet above sea level. They consist of ribs and vertebrates that have been fossilised and preserved. They date back 205 million years ago, long before the asteroid that killed the giant raptors in the first two links. In fact, very near, or at the end of theTriassic, a major extinction event in its own right. The Alps were nothing like they are now back then as they are thought to have formed, in mainstream theory of mountain building, when the African plate pushed up against the European plate much more recently [but still millions of years ago]. In other words, what is now the Alps could well have been a fairly flat landscape. In that situation a flood of water, tsunami like, could have rushed across southern Europe, and elsewhere.
