Predator X


A marine monster described as the most fearsome animal ever to swim in the oceans boasted a bite up to 11 times as strong as that of Tyrannosaurus rex.

The fossil remains of the huge pliosaur were dug up last summer from the permafrost on Svalbard, a Norwegian island close to the North Pole.

Analysis revealed that it was a turbo-charged swimmer. Its front flippers allowed the creature, dubbed Predator X, to cruise along comfortably but when prey came into range the power of its hind flippers kicked in to provide extra acceleration.

Measurements of its jaw and the killing power of its dagger-like teeth have shown that it could bite down with a force of 33,000lb per square inch compared with T. rex’s 3,000lb per square inch. Alligators have the strongest bite today with about 2,500lb per square inch.

New Dinosaur Species Revealed on PREDATOR X - Funny videos are here
Researchers have been astonished by the size of the reptile, which exceeded even that of another pliosaur, called The Monster, which was found at the same site a year earlier.

Predator X is thought to have been at least 50 feet long, perhaps more, and measurements of its bulk suggest that it would have weighed in at 45 tonnes.

Its discovery was announced yesterday in Oslo by Jørn Hurum, of the University of Oslo, who led the expedition to dig up the remains. At least 20,000 fragments have been recovered including most of the jaws, which were 10 feet long. Dr Hurum said: “It was the most ferocious hunter ever. It’s like a turbo-charged predator. This is a very, very large carnivore.”

He added that Predator X was smaller than the biggest marine reptile yet known, a 75ft ichthyosaur from 210 million years ago, and was about the same length as the largest fossil shark to have been identified by palaeontologists. Predator X, however, was armed with much bigger teeth and, with its ability to close in at enormous speed, would have been much faster and deadlier than either of them.

Dr Hurum believes that Predator X and The Monster are likely to represent the same species of pliosaur. “Its anatomy, physiology and hunting strategy all point to it being the ultimate predator — the most dangerous creature to patrol the Earth’s oceans.”

The turbo-charge feature of its hind flippers was identified in tests by John Long, of Vassar College, New York State, using a four-flippered robot called Madeline.

Researchers had been puzzled about why the marine predator should have needed four flippers when the front two were perfectly adequate for it to swim well.

A CT scan of a pliosaur skull held at the Natural History Museum in London has showed that the ancient marine predators had a brain the same shape and proportion as the great white shark, which is regarded as today’s “perfect killing machine”.

Tiny flying dinosaur found


"Scientists believe they have found evidence of a tiny pterodactyl in China.

The toothless flying reptile has been studied at Brazil's national museum, where it was found to have a wing span of just 250 millimetres (9.8 inches) and unexpectedly-curved toes.

Most pterodactyl fossils are found in coastal areas but this specimen was discovered in the western part of China's Liaoning province, which would have been covered in forest 120 million years ago.

As a result, scientists have called the reptile "Nemicolopterus crypticus," which means 'hidden flying forest dweller',

Palaeontologist Alexander Kellner said: "The fundamental importance of this discovery is that it opens up a new chapter in the history of evolution of these flying reptiles.

"So far, we never knew that these animals were adapted to live in the canopies of the trees, which is the case of the Nemicolopterus."

The tiny fossilised reptile has a skull that is not fully fused, so it died before reaching adulthood, but the ends of the bones were developed, so it was not a hatchling either."

Earths first Spaceport?


Sooner or later, we gotta get of this planet. Me thinks sooner, judging reports about global warming and the on-coming War of the Cultures.

Over-population and the usage of our natural resources means that we must find some resources (and even somewhere else to live) before Earth has another Extinction Level Event (ELE). We know a giant rock is coming to change the order of things. It has happened 5 times we know of already. The dinosuar event, 65 million years ago in the Chixalub in Mexico is just the fifth ELE that they know of.


And of course I havent mentioned Super Volcanoes, Global Plagues, Ice Ages, and good old fashioned Thermal Nuclear Death.

sings "We gotta get out of this place". But how?

It is actually really fuel intensive to get of this planet. So much of a rockets fuel is just needed to break the Earths atmospere. You probably couldnt launch a vessel that was meant to go deep space and back again with conventional rocket fuel. It would probably weigh too much. Thats why they dont paint the fuel cells on the shuttle. The extra weight would mean extra fuel to cover it, and even more fuel to cover the extra weight of the extra fuel! phew!

So if you could launch from somewhere where you didnt have to break the Earths atmosphere, you could take so much extra fuel with you for your deepspace exploring or mining trip! Nice :)

And finally, what is the main componant of rocket fuel? Hydrogen, the H in H2O.

Which brings us to that magnificent photo from the Mars Exress showing a crater at the north pole of Mars full of water ice. It is about 10km across and about 200/400 meters thick. And its not the only crater at the pole. Concieivably, you could build a base at the poles of Mars, build a machine that converts water into Hydrogen fuel, and launch missions from there.

Many years in the future, I fear; but we have the technology now, not the political will.

Peace out.
