The size and spacing of the 106-million-year-old tracks suggest the crocodylomorph was 2 to 3 meters long — a fearsome predator similar in size to its modern descendants, researchers report June 11 in Scientific Reports. The tracks were found in the fossil-rich Jinju Formation, home to the remains of a wide variety of animals including dinosaurs. It's tough to identify a species from footprints, says paleontologist Martin Lockley of the University of Colorado Denver. "Short of finding the animal dead in its tracks, there's always a little bit of uncertainty."

Don't we already know this from T-Rex when we were 6 years old? |

T-Rex is not classified as a Crocodlylomorph or even a lizard,although it is classified as a reptile so no, this is new information. :) |
