3. The Toothy Masiakasaurus Knopfleri
This one was so dangerous that there is no other predator dinosaur with the kind of teeth that this dinosaur possessed. It had front teeth which were projecting forward, and it is these teeth that it could use when slicing and then cut its captives into chunks that were chewy by using its rears that looked like blades.

Also known as a vicious lizard, this dinosaur with 6 feet body length, is believed to have feasted on lizards, fish and other critters about 65 – 70 million years ago in Madagascar, an island nation of Africa. It had a long neck and tail which made up most of its length.
