Don't let the ferocious name of a new armored dinosaur found in Montana fool you: Zuul crurivastator (the new genus is a nod to the main Ghostbusters villain) is actually quite the softie. At least in terms of soft tissue. The wonderfully preserved specimen has loads of it, opening up a lot of possibilities for further research.
Zuul roamed North America about 75 million years ago and was about as badass as an herbivore can be. It was a large ankylosaurine, one of the armor-plated dinos that resembled tanks. Its tail ended in a weighty club.
