Groundbreaking new science is changing what we thought we knew about how dinosaurs looked, moved, and lived. Newfound troves from the Moroccan desert suggest that the immense predator Spinosaurus spent much of its time in the water. And in Chile, scientists have discovered a shocking new therapod. Unlike its cousins, Velociraptor and T. rex, Chilesaurus consumed a vegetarian diet. Join leading paleontologists Nizar Ibrahim and Sebastián Rozadilla for stories and conversation about the evolving science of dinosaurs.

Nizar Ibrahim
German/Moroccan paleontologist, anatomist, and National Geographic Explorer Nizar Ibrahim has unearthed spectacular dinosaur bones, rare fossil footprints, giant prehistoric fish, crocodile-like hunters, and a new species of giant flying reptile with a 20-foot wingspan that lived 95 million years ago.

Sebastián Rozadilla
Born in La Plata, Argentina, from an early age Sebastián Rozadilla had a fascination with nature. He began his studies at the National University of La Plata and worked at the Bernardino Rivadavia Argentine Museum of Natural Sciences studying herbivorous dinosaurs.
