Pinacosaurus Pronunciation

Fun Facts

• ✓Multiple juvenile Pinacosaurus skeletons have been found buried together in groups of up to six individuals, giving scientists rare direct evidence that young ankylosaurs may have traveled in social groups.
• ✓Pinacosaurus had a series of mysterious extra holes near its nose that no other ankylosaur had quite like this, and scientists still debate whether they helped with smell, heat regulation, or something else entirely.
• ✓The very first Pinacosaurus fossils were collected during the famous 1923 American Museum of Natural History Central Asiatic Expeditions led by Roy Chapman Andrews, the real-life adventurer often said to have inspired Indiana Jones.
• ✓Pinacosaurus lived in what was a semi-arid desert environment in Late Cretaceous Asia, meaning this armored plant-eater survived in conditions more like a dry scrubland than a lush jungle.
• ✓A brand-new second species, Pinacosaurus hilwitnorum, was only officially named in 2026, meaning this dinosaur is still actively being studied and described by scientists right now.
