Researchers may understand more about the evolutionary link through technology, too. While the team has already conducted a CT scan, there are hopes of performing future 3D scans that help compare the iguanodontid's brain to that of present-day creatures.

Don't expect to see too many discoveries like this in the future. The scientists believe they got lucky -- they theorize that the dinosaur's brain was preserved in highly acidic water (possibly from a bog or swamp), protecting its form before the whole animal was buried. However, the revelation may prompt other paleontologists to revisit fossils they already have in case they missed something.
