A new study of these formidable predators' chompers has revealed concentrated deposits of iron along the serrated tearing edges and the tips of their teeth, helping to keep them razor-sharp for tearing the flesh from the prey they devour.In fact, so much iron is concentrated along the sharp edges of komodo teeth that they are tinted orange.
"We want to use this similarity to learn more about how carnivorous dinosaurs might have ate and if they used iron in their teeth the same way as the Komodo dragon.
They used advanced microscopy and spectroscopy techniques to analyze the composition of Ganas' teeth, and found that orange tint along the serrated edge and at the tip is the result of iron sequestered in that location."Unfortunately, using the technology we have at the moment, we can't see whether fossilized dinosaur teeth had high levels of iron or not.
