Spinosaurus Alongside a River and Stone Arch
The page depicts a Spinosaurus featuring its characteristic sail standing beside a wide prehistoric river on a sandy bank near a natural stone arch formation.
Aquatic Adaptations of Spinosaurus
Spinosaurus was adapted for a semi-aquatic lifestyle, spending much of its life swimming in river systems across North Africa. Its tall spine sail, supported by long neural spines, may have helped regulate body temperature or served as a display signal while swimming. Riverbanks with natural stone arches formed through millions of years of water erosion in ancient delta networks.
