Concavenator: The Hump-Backed Spanish Dinosaur

Concavenator was a medium sized predatory dinosaur. Its fossils are found in the Early Cretaceous La Huérguina Formation, which are now part of the Spanish providence of Cuenca. Concavenator was a member of Carcharodontosauridae, a clade of theropod dinosaurs which included the massive Giganotosaurus. Although Concavenator was far smaller than many of its cousins, it is notable for other, more unique reasons. It had a strange hump on its back, the purpose of which remains unknown. There are also bumps on Concavenator's arms, which may have been quill knobs that held large feathers in place. 00:00 - Introduction 00:28 - Discovery 01:00 - Classification and Size 01:38 - Anatomy 02:33 - Hump 05:11 - Quill Knobs 08:38 - Scales 10:21 - Pack Hunting 12:34 - Paleoenvironment 13:40 - Conclusion 14:09 - Outro Sources: https://repositorio.uam.es/handle/104...
