Megalodon, The Mega Shark

Megalodon is a giant ancient species of shark are considered to be the first shark species that exist. Live about 20 to 1.2 million years ago, this shark is bigger than a cruise ship. His name itself means "big tooth". These animals, including sharks in the waters that seldom rise to the surface except to find prey. Although the issue of the spread of this shark has never been found alive, many scientists argue that the shark is still alive, and includes living fossils. Descendants near white shark is a shark. Dinosaurs became extinct because the other affected by the weather, while Megalodon live in a vast ocean, so it is not so affected by the weather, consequently there are still some who are still alive. Here is the video appearance of Megalodon, please watch:

There's also a news about it:

PANAMA (AP) - Panama is home to big-toothed creature called a Megalodon, a shark in the world with more weight than a great white shark.
A residential area of ​​10 million-year-old hybrid of the extinct Megalodon shark found in Panama, according to researchers from the University of Florida who reported their findings in the journal PLoS ONE.

Aka Big Tooth Megalodon shark and fish was estimated as the largest in the world. Able to grow about 67 feet long and heavier than a great white shark.

"The study provides evidence about the Megalodon's behavior in the fossil record," said lead researcher Catalina Pimiento, who had just completed a master's degree in zoology from the University of Florida and worked at the Museum of Natural History as an expert on vertebrate paleontology.

"Behavior can not difosilkan, but we were able to interpret the ancient protection strategy used by sharks, based on the fossil record."

Past data indicate that the region became an area of ​​ancient sharks peranakkan is Paleocene Williamsburg Formation and Oligocene Chandler Bridge Formation in Southern California, which became the basis of the presence of young Megalodon tooth.

"Collections in advance about a rough analysis of the region as a study specimen, which also provides support for the presence of the nest area of ​​ancient sharks," he said referring to the findings Pimiento Discovery News in September.

For the latest study, he and his team collected 400 fossil shark teeth between 2007 and 2009 from the shallow waters of Gatun Formation is connected with the Pacific Ocean and Caribbean Sea during the Miocene Epoch in Panama.

Most of the 28 small-sized specimens Carcharocles Megalodon. But more analysis to determine the size is not related to the position of teeth in the jaws of the species at the end of the Miocene period.

Expert University of Florida's vertebrate paleontology graduate Dana Young Megalodon teeth Egret measure Gatun Formation of Panama on May 6, 2010. Ehret is the author of the study describes the first neotropis Megalodon Peranakan area, four teeth obtained from the Gatun Formation Megalodon abandoned by adults in Florida.

"Our study provides results that specimens representing most of the young Megalodon measuring between 2 to 10.5 meters in length," said Pimiento.
