Our planet Earth was once a home to a numerous creatures that you could not imagine in your wildest dreams. One such creature was Anomalocaris. Anomalocaris or abnormal shrimp is considered to be the Earth first super predator that swim the Cambrian seas some 541 million years ago.
This predator with long body up to length of 2 m and unique pair of eyes for night hunting suggest that Anomalocaris was indeed top predator that mostly hunted smaller trilobites and other sea animals.
Fossilized remains of this animal were found across the globe in Canadian Burgess Shale formation, Australia, China and across the United States before becoming extinct some 485 million years ago at the beginning of Ordovician era.
