Air-breathing, cold-blooded vertebrates that have scaly bodies as opposed to hair or feathers; they represent an intermediate position in evolutionary development between amphibians and warm-blooded vertebrates, the birds and mammals, those named Reptiles.

Remains of a bus-sized prehistoric "monster" reptile found on a remote Arctic island. It may be a new species never before recorded by science.

Initial excavation of a site on the Svalbard islands in August yielded the remains, teeth, skull fragments and vertebrae of a reptile estimated to measure nearly 40 feet long, said Joern Harald Hurum of the University of Oslo.

The reptile appears be the same species as another sea predator whose remains were found nearby on Svalbard last year. His team described those 150-million-year-old remains as belonging to a short-necked plesiosaur measuring more than 30 feet — "as long as a bus ... with teeth larger than cucumbers."

The short-necked plesiosaur was a voracious reptile often compared to the Tyrannosaurus rex of the oceans.

Mark Evans, a plesiosaur expert at the Leicester City Museums in Britain, said he not know enough about the Norwegian find to comment on it specifically. But he said new types of the sea reptiles are being found regularly.

There is no doubt that scientist almost every year find something new and interesting all over the world, But It seems nowadays mere mortals don’t even know a lot about the prehistorically civilization.

The majority of reptile species are oviparous (egg-laying) although certain species of squamates are capable of giving live birth. This is achieved, either through ovoviviparity (egg retention), or viviparity (offspring born without use of calcified eggs). Many of the viviparous species feed their fetuses through various forms of placenta analogous to those of mammals with some providing initial care for their hatchlings.

Paleontologists from the University of Oslo, led by Dr. Joern Hurum and Hans Arne Nakrem, made the discovery on August 2006. The remains, which are very well preserved as well as being unique in their completeness, are the first complete skeleton of a Pliosaurus ever discovered, although parts of pliosaurs have earlier been found in England, Russia and Argentina. Pliosaurus, one of the largest-ever marine predators, lived in the ocean and hunted other smaller marine reptiles.

Development of science and technology day by day allows us to understand how wide spread civilization has been exploded. A range of work papers suitably become the books, those are red by new generations, and civilization is still under development.
