TITANBOA

Upto 42 ft long, weighing around 2500 pounds could have easily guped down a grown up man.

ANVILHEAD  SHARK - STETHACANTHUS

Stethacantus had a dorsal fin shaped like an anvil. Weird!

MEGALADON - MONSTER SHARK

This fish was a moster that could have send chills down your spine. Imagine the size and wrath of twenty Great White Sharks in one.

JAEKELOPTERUS - THE SEA GOD SCORPION

Much bigger (measuring around 8 ft) than its modern cousins and much much more ferocious as well. 

QUETZALCOATLUS - TERROR IN THE SKY

QUETZALCOATLUS - TERROR IN THE SKY

These ace fliers terrorized smaller animals during the Late Cretaceous with a sharp stork-like beak and a wingspan of 36 feet.

ANTHROPLEURA - GIANT MILLIPEDE

this nightmare bug was so big it didn’t have a single natural predator. The Arthropleura was not big on hunting either and preferred munching on juicy fruits and seeds on the ground.
