"Fossil footprints show some crocodile ancestors walked" Topic

… on two legs

"Fossil tracks preserved in a South Korean rock formation are the first footprint evidence that some ancient ancestors of modern crocodiles walked on two legs. 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." But the beautifully preserved prints made it possible to attribute them to Batrachopus, a genus of fossil tracks known to be made by crocodylomorphs…"

Now that's a bit scary; crocodiles running about on two legs…

Upright lizards are one of the advanced species thought to be possible via evolution, so bring on more episodes of "V", and/or the Gorn Star Trek episodes, just for grins.

Glad you like them boys!. (smile)
