Spinosaurs shed salty tears to survive in coastal waters

AI Insight

Fossil evidence indicates that some spinosaur dinosaurs possessed specialized salt glands similar to those found in modern marine birds and crocodiles. These glands would have allowed spinosaurs to actively excrete excess salt from their bloodstream, enabling them to survive and hunt in brackish or saltwater environments. This adaptation suggests these predatory dinosaurs were more aquatically adapted than previously understood.

Why it matters

This finding provides important evidence about dinosaur physiology and ecological diversity, showing that some dinosaur species developed sophisticated adaptations for life in marine or estuarine habitats. It changes our understanding of how dinosaurs colonized different environments and evolved specialized hunting strategies in aquatic ecosystems.
