Dinosaurs may have been eating seaweed 100 million years ago
The Brief
- Researchers found chemical signatures in fossilized dinosaur teeth suggesting coastal dinosaurs and other prehistoric animals ate seaweed and other ocean foods.
- The evidence points to these diets more than 100 million years ago.
- The sources available here are a short summary, so the specific methods and sample details are not confirmed.
Why it matters
It adds evidence that some dinosaurs in coastal habitats used marine food sources, which can refine reconstructions of their diets and ecosystems.
Who’s affected
- paleontologists and palaeoecologists
- readers interested in dinosaur diets and ancient ecosystems
