酷東西

趣味知識

Kryptohadros is a type of hadrosauroid, which means it is a relative of the famous duck-billed dinosaurs like Edmontosaurus.1

Its fossils were found near the village of Vălioara in Romania, at a site called Fântânele-3.2

The skeleton was discovered between 2022 and 2024, and it includes parts of the skull, ribs, tail bones, and a leg.1

Kryptohadros lived about 72 to 66 million years ago, during the Maastrichtian stage of the Late Cretaceous.3

Scientists think Kryptohadros belonged to a group called Telmatosauridae, which includes other European duck-billed dinosaurs like Telmatosaurus and Tethyshadros.1 2

The name Kryptohadros means 'hidden hadrosauroid' because it was found close to a known fossil site but remained undiscovered for many years.1
