[Animals] Massive dino from Brazil ate 'like a pelican,' controversial new study finds. Why is it causing an uproar?

The study reveals new information about the carnivorous dinosaur Irritator challengeri, but the research has been criticized because the fossils may have been illegally removed from Brazil.

A large predatory dinosaur related to Spinosaurus may have scooped up prey "like a pelican" by extending its lower jaw, European researchers propose in a new study. But the findings have upset some paleontologists who contest that the fossils were illegally taken from Brazil and should be returned to their country of origin.

The dinosaur at the center of the controversy is Irritator challengeri, a member of the family Spinosauridae — a group of bipedal, carnivorous dinosaurs with long, crocodilian-like snouts. The species, which grew to a max length of around 21 feet (6.5 meters), was first described in 1996 from 115 million-year-old fossils uncovered in the Araripe Basin of northeastern Brazil and later shipped to Germany, where they now reside in the Stuttgart Museum of Natural History in the state of Baden-Württemberg. 

In the new study, which was published in the journal Palaeontologia Electronica, researchers digitally reconstructed the skull from the I. challengeri specimen housed in Stuttgart and discovered that the species' lower jaw could spread out to the sides, widening the animal's pharynx, the area behind the nose and mouth. This is similar to how a pelican widens its lower beak to scoop up small fish, suggesting that I. challengeri likely fed in the same way, the researchers wrote in a statement.

The new analysis also revealed that, due to its eye placement, I. challengeri would have naturally inclined its snout at a 45-degree angle and been capable of rapid-yet-weak bites. When combined, these features suggest that the snout would have been well suited to quickly scooping prey out of shallow water, the researchers wrote.
