Fact: “First spinosaurid betrayed by fish scales inside its rib cage.”

Description: Baryonyx documents semi-aquatic specialization within Spinosauridae prior to the exaggerated proportions of Spinosaurus. Hooked manual unguals seized slippery prey while conical teeth pierced lungfish and juvenile sturgeons recorded as stomach contents. Its rostrum resembles gharial crocodilians, signaling lateral-snapping strikes.

Features:
  - Forelimb claws reach ~30 cm along their outer arc
  - Stomach contents preserve acid-etched fish scales
  - An elongate snout widened distally into a rosette

Related genera: Spinosaurus, Suchomimus, Irritator
