A new species of prehistoric sea monster unearthed in Nevada chowed down on prey its own sizea€”the first ocean predator that evolved to do so, a new study says. The bus-size beast was an early ichthyosaur, part of a group of reptiles that prowled the world's seas during the dinosaur era. The Thalattoarchon fossil, partially excavated in 1998, was unusually well preserved, including the skull, fins, and entire vertebral column.
But more compelling to Fröbisch were reports of the animal's fearsome teeth, briefly spotted on the last day of the 1998 expedition.
So, in 2010, Fröbisch and colleagues returned to the Nevada site to dig up the rest of the fossil. Thalattoarchon's modern counterparts would be orcas and great white sharks, both of which will take on similar-size prey.
The sea monster's discovery also shows how ecosystems can bounce back from even the most extreme events, Fröbisch noted. Despite thriving some 160 million years, Thalattoarchon and fellow ichthyosaurs went extinct for unknown reasonsa€”leaving no living relatives. The sea monster study was published in the early-electronic issue of the journal Proceedings of the National Academy of Sciences. After spending centuries obscured in myth, the real giant squid is finally becoming known to humans through photos and film taken by dedicated scientists and amateurs around the world. When a 20-foot (6-meter) predator catches you off guard, will you know how to defend yourself?

Gaze into the face of the frilled shark, a creature little-changed over millions of years and usually hidden in the ocean depths, thousands of feet below the surface. This material is based in part upon work supported by the National Science Foundation under Grant No.
Incredible: Robbie Shone, 32, has travelled the globe for the world's best cave but seems to have found the best one in Sheffield. Talented: Mr Shone used his rope and abseiling skills - gained from his previous job inspecting tall buildings and bridges for structural damage - to access the caves to photograph and record details about them for the first time. The giant storm drain called Megatron looks stunning when lit up and is all the more incredible because it is located directly beneath Sheffield City Centre. Mr Shone said: 'Exploring somewhere no one else has been before, is a very, very special feeling. Dangerous: A cave explorer stands in the main chamber of Gaping Gill in the Yorkshire Dales as it is hit by a raging flood pulse. Different world: The photographs are a collection of six years work by Mr Shone from some of the most beautiful and remote caves ever discovered.

A Chinese tourist has taken what he says is a photo of a "monster" hiding in the valleys of Huairou, in the north of Beijing. In the process, the scientists discovered an enormous skull and jaw-laden with large, sharp teeth that are big enough to carve up other large marine reptiles, she said.

The presence of a top predator like Thalattoarchon during that time period shows that the system was intact within a relatively short time, since marine ecosystems build from the bottom of the food chain up. Learn why sharks attack and what you can do to keep your next encounter from being your last. Mr Shone used his rope and abseiling skills - gained from his previous job inspecting tall buildings and bridges for structural damage - to access the caves to photograph and record details about them for the first time.The explorer is so committed, he even spent 13 days in a row underground - camping, sleeping and eating in a remote cave in Vietnam. It pushes me on to keep finding unexplored caves.'The more difficult caves are the vertical ones when you're suspended on a rope for a long time. We stayed for three months exploring caves.'They could be quite dangerous as they had a large amount of white water flowing through them.

Sometimes you don't even know when you're going to reach the bottom.'You can run out of rope before you reach the cave floor, in which case you have to go back up and get a longer rope. So care had to be taken when crossing the river because if you slipped in it would be quite dangerous. I took a few pictures of it, but I am now terrified." The image of the strange flesh-coloured creature nestled among the bamboo is certainly striking, and has a marked resemblance to the creature Gollum from the Lord of the Rings films.
