Scientists have discovered that the serrated edges of Komodo dragons' teeth are tipped with iron. The study gives new insight into how Komodo dragons keep their teeth razor-sharp and may provide clues to how dinosaurs like Tyrannosaurus rex killed and ate their prey.
Scientists have discovered that the serrated edges of Komodo dragons' teeth are tipped with iron. The study gives new insight into how Komodo dragons keep their teeth razor-sharp and may provide clues to how dinosaurs like Tyrannosaurus rex killed and ate their prey.Led by researchers from King's College London, the study gives new insight into how Komodo dragons keep their teeth razor-sharp and may provide clues to how dinosaurs like Tyrannosaurus rex killed and ate their prey.
To understand the chemical and structural make-up of Komodo dragon's teeth, scientists scoured museums for skulls and teeth of Komodo dragons and studied the teeth of Ganas, the 15-year-old Komodo dragon who had lived at ZSL conservation zoo, London Zoo. Dr Aaron LeBlanc, lecturer in Dental Biosciences at King's College London and the study's lead author said:"Komodo dragons have curved, serrated teeth to rip and tear their prey just like those of meat-eating dinosaurs. 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.
"With further analysis of the Komodo teeth we may be able to find other markers in the iron coating that aren't changed during fossilisation. With markers like that we would know with certainty whether dinosaurs also had iron-coated teeth and have a greater understanding of these ferocious predators."
Scratches on dinosaur teeth could reveal what they really ate. Dental microwear texture analysis has now been used to infer the feeding habits of large theropods, including Allosaurus and T. ...
