Information
Living 70 million years ago in Alberta, Canada, Hesperonychus elizabethae tipped the scales at just 1 meter long (3 feet) and weighed in at 1.9 kilograms(2 pounds). Yet this animal, like its close relative Velociraptor, was swift, intelligent and wielded a killing claw on its toe. But would a pack be a match for Paleosaniwa canadensis, a 1.8 meter (6 foot) monitor lizard that terrorized Alberta, Canada and Montana and North Dakota, America with serrated teeth, deadly claws and venom 70-65 million years ago.
The fight
70 million years ago in Alberta, a hungry Paleosaniwa is looking for prey.This individual is looking for prey to give to his mate. He unknowingly treads into the territory of a pack of Hesperonychus. The animals jump onto the Paleosawina's back and attempt to kill it, but the lizard's scales are too thick to do any real damage. The enraged animal quickly slashes and bites its attackers, and then moves in on the rest of the pack. In 20 minutes, the scar-covered Paleosawina has killed, or has injected its venom into every Hesperonychus. He then carries a few carcasses and brings them to his mate.
