Controversial Study Reveals Brazilian Dinosaur's Unique Feeding Habits.

A new study proposes that Irritator challengeri, a large predatory dinosaur related to Spinosaurus, fed by extending its lower jaw and scooping up prey "like a pelican." However, the fossils were illegally taken from Brazil and should be returned to their country of origin, causing controversy among paleontologists. The study's researchers acknowledge the "possibly problematic status" of the fossils, but some believe that publishing studies based on illegally taken fossils validates scientific colonialism and makes it harder for poorer countries to contribute to science.
