Gonkoken Nanoi

News: Gonkoken nanoi is the name of a new species of duck- billed dinosaur that was discovered in Chile recently.

About:
• Gonkoken nanoi was a herbivorous dinosaur that lived 72 million years ago in what is now Chilean Patagonia. It was about four meters long and weighed a ton. It could walk on both two and four legs, and had a flattened, waterfowl-like snout.
• It is the first species of this kind of dinosaur to be found in the southern hemisphere, and it challenges the previous beliefs about their geographic distribution and evolution.

How do duck-billed dinosaurs differ from other ones?
• As their name suggests, duck-billed dinosaurs had broad, flat, and elongated snouts that ended in toothless beaks. These beaks were useful for nipping at low-lying vegetation, such as ferns, horsetails, and cycads.
• Duck-billed dinosaurs had hundreds of teeth arranged in complex structures called dental batteries. These teeth were constantly replaced as they wore out, and they formed effective grinding surfaces for chewing tough plant matter.
• Some duck-billed dinosaurs, especially those belonging to the subfamily Lambeosaurinae, had hollow crests or tubes on top of their heads. These crests varied in shape and size among different species, and they may have been used for display, communication, or thermoregulation. Some examples of crested duck- billed dinosaurs are Parasaurolophus, Corythosaurus, and Lambeosaurus.
