Shark Week: Sharkzilla

To celebrate the monumental 25th anniversary of Shark Week, Discovery is resurrecting the largest shark to ever swim in our oceans, a predator so fierce he could have bitten a T. rex in two: the mighty Megalodon. The size of a city bus, these prehistoric sharks were as large as 60 feet long and weighed at least 100,000 pounds. This shark was the ultimate Jaws: Megalodons had 250 serrated teeth, each six inches long, set in jaws six feet wide and eight feet tall. In response to questions raised by a Miocene era crime scene, a team of engineers and paleontologists work together to design and build this monster, to see just what he was capable of. Enlisting the help of MythBusters Kari Byron, Grant Imahara and Tori Belleci, the team puts these chilling chompers to the test.
