70-million-year-old crocodile relative with dinosaur-crushing jaws found in Argentina

Seventy million years ago, southern Patagonia was home to dinosaurs, turtles, and mammals—but also to a fierce crocodile-like predator. A newly discovered fossil, astonishingly well-preserved, reveals Kostensuchus atrox, a powerful 3.5-meter-long apex predator with crushing jaws and sharp teeth capable of devouring medium-sized dinosaurs. As one of the largest hunters of its time and the first of its kind found in the Chorrillo Formation, this find offers rare insight into the prehistoric ecosystem at the close of the Cretaceous.

The Chorrillo Formation formed around 70 million years ago, during the Maastrichtian age at the very end of the Cretaceous period. At this time, southern Patagonia was a warm, seasonally humid landscape of freshwater floodplains, home to creatures like dinosaurs, turtles, frogs, and various mammals.

Grandpa, that's where you vanished off too!

Seriously though, this is pretty cool.  I love that we're still discovering new prehistoric creatures.

And then made religious literalists to annoy us.
