The Jurassic Ankylosaur Revolution: A Paleontological Discovery of the Weird Armored Dinosaur that Once Roamed the Northern Plains This book is an exploration of Spicomellus afer, a remarkable Middle Jurassic dinosaur discovered in Morocco's Atlas Mountains. As the earliest known ankylosaur, Spicomellus challenges conventional understanding of armored dinosaur evolution with its extraordinary array of spikes, bony collars, and pelvic shields. Drawing on fossil evidence unearthed between 2021 and 2023, the book provides the anatomical, ecological, and evolutionary significance of this unique species. Through ten chapters, it traces the historical context of ankylosaur research, the specifics of Spicomellus' morphology, and the implications for paleontological study. The narrative seamlessly integrates rigorous scientific analysis with vivid reconstructions of the Jurassic coastal floodplain, providing readers with an immersive journey into the life and environment of this heavily armored herbivore. The book also addresses ongoing research efforts and the challenges of preserving fossil sites, providing a comprehensive perspective on the scientific process behind such discoveries.
