Why are these beaches so rich in fossils?

     From :- BBC World News    By :-  Dave Gilyeat - South of England   Editted by :-  Amal Udawatta  Getty Images The Dinosaur Isle Museum has its very own Iguanadon skeleton, which was discovered on the Isle of Wight An amateur fossil hunter recently discovered a rare fragment of the world's oldest marine crocodile in Lyme Regis, so what is it about the Jurassic Coast and the Isle of Wight that makes them so rich in prehistoric fossils? In the early Jurassic period ichthyosaurs and plesiosaurs ruled the waves in what is modern-day Dorset, amid schools of smaller weird and wonderful sea creatures. Later, in the Cretaceous period, the Isle of Wight was the "acme of dinosaur diversity in the UK", according to palaeontologist Dr David Button, with specimens of almost every shape and size. We know this because of the unique geology of these places, where seas continually erode the cliffs and new and exciting fossils emerge into the light of day....

'Predators that just run in and grab, stab and kill': The deep cave bacteria resistant to modern medicine

Their only food source is each other. The survival tactics they develop make them resistant to almost all antibiotics. Now scientists hope to use their tricks to inspire new drugs and treatments. Deep underground, plunging 1,604ft (489m) beneath the Chihuahuan Desert in southern New Mexico, lies the Lechuguilla Cave, a cavern which stretches on for 149 miles (240km). There is no light, and little to eat either. Any living thing must eke out an existence under conditions of near starvation. "You can go in an entrance and travel for 16 hours in one direction before you get to the end of it," says Hazel Barton, professor of geological sciences at the University of Alabama.  "So you're a very, very, very long way from the entrance. You're iso...
