400 Million years old megafish could snap shark in two

Scientists report about a megafish that lives about 400 million years ago that had a bite powerful enough to chop a shark in two.
A well-known denizen of museum displays, Dunkleosteus terrelli could have exerted up to 1,200 pounds of force with its bite, the investigators estimate. When applied along its jagged snapping-turtle-like jaws, such a force would translate to about 8,000 pounds of pressure per square inch, the researchers find. "It was probably the first vertebrate that was able to fragment its prey before swallowing," says zoologist Mark Westneat of the Field Museum in Chicago.
Pretty impressive.
