In dinosaur news this week:

• A New Jurassic neornithischian dinosaur with a Voice Box. Pulaosaurus qinglong, from China’s Tiaojishan Formation, has only the second larynx ever found preserved with a non-avian dinosaur. Source
• The small ornithischian Enigmacursor mollyborthwickae was found in the Morrison Formation of Colorado. Reminding us that it wasn't just huge sauropods and stegosaurs eating plants in the Late Jurassic. Source
• A new ornithopod named Obelignathus septimanicus was identified from a stronger jawbone than other Late Cretaceous ornithopods (like Rhabdodon) in what is now southern France. It's name refers to the French comic character Obelix who has superhuman strength (like the "unusually robustly-built" jawbone on Obelignathus). Source
• An Early Cretaceous basal hadrosauroid, Cariocecus bocagei, was named from Portugal. It had a fused upper jaw and cheekbone, possibly letting it chew tougher plants than its relatives. Source
