Picture the fearsome movie creatures of “Jurassic Park” crossed with the shark from “Jaws.” Then super-size to the biggest predator ever to roam Earth.
Lead discoverer Nizar Ibrahim of the University of Chicago said it’s so weird that studying it was like working on an extraterrestrial.
The 50-foot (15 meter)-long predator is the only known dinosaur to live much of its life in the water.
Scientists had some bones from the beast already, but the new skeleton discovery forced a major rethinking of what it looked like some 95 million years ago.
The result was described Thursday in the journal Science.
