Description: Spinosaurus is among the most derived spinosaurids, famous for an elongate series of neural spines forming a dorsal sail or hump. Dense postcranial bones, a long, narrow snout lined with conical teeth, and a tail with expanded lateral lobes all support semiaquatic foraging along North African rivers and mangrove-fringed deltas, with piscivory complemented by opportunistic feeding on other vertebrates.

Features:
  - Neural spines could exceed ~2 m in height, forming the sail
  - Conical, weakly laterally compressed teeth suited to impaling slippery prey
  - Robust forelimbs with trenchant unguals adapted for seizing prey

Related genera: Baryonyx, Suchomimus, Irritator
