The discovery took a team of more than 100 researchers who began excavating the site in June after a quarry worker reported feeling "unusual bumps" while working in the area.
The examination offered insight into predator-prey dynamics during the dinosaur age. Of about 600 bones checked, bite marks - often deep grooves left in stout bone - were detected on 68 of them ...

[2] [4] She then gathers information about what is known about the subject's habitat; what other creatures from the same area looked like; and how the subject's role as a predator or prey might have affected the patterns and coloration of their exteriors. [1] [2] She also examines fossils and consults other sketches and technical drawings. [4]
The predator, which was larger than a person, likely used its wide, flat head and front teeth to suck in and chomp unsuspecting prey, researchers said. Its skull was about 2 feet (60 centimeters ...
