The vertebrai of the 20 foot shark were found in Cretaceous limestone – dating around 100 million years ago. Another shark fossil was unearthed in Kansas a short time before this one, and panned out at 27 feet in length. These have got paleontologist tongues wagging as sharks during the dinosaur age, apparently, were thought to be quite small and insignificant creatures (although shark teeth are one of the commonest fossils you will find in limestones and various other sediments from the past). It seems sharks in the age of the dinosaurs were major predators and not to be dismissed lightly.
At http://archaeologynewsnetwork.blogspot.co.uk/2015/06/ice-age-camel-bones… … the camel bones were found by miners in the Yukon and again, the discovery has caused paleontologists to rethink accepted ideas. The fossils were found in a gold mine in the Klondike and it seems they are similar to camels of Asia and Arabia – in the modern world. How did they get there. The theory is that they spread north during a warm period – but when?
Well, one of the periods it could have happened was during the last interglacial – see http://archaeologynewsnetwork.blogspot.co.uk/2015/06/dramatic-ice-sheet-… … when an ice sheet in the north collapsed suddenly. It was abrupt – unliike the last Ice Age when the melting glaciers were interrupted by several bouts of cold weather that led to a return to near Ice Age conditions (before finally stabilising at the beginning of the Holocene).
Bill Napier has connected the Taurid complex with the end of the last Ice Age, the Earth encountering streams of dense material from a large comet. What this latest research shows is that the end of the last Ice Age was completely different to the end of the Ice Age that occurred before it and in a way, tends to support the Napier theory, or rather, does not contradict it, in that the end of the last Ice Age was unique in the manner it stopped and restarted on several occasions (which fits in with a scenario like the Taurid complex). The end of the Ice Age at 135,000 years ago differed. It was sudden and abrupt – a shift in the axis of rotation, or a pole shift, might account for that, or any of a dozen other theories.
