Scientists measure blood of dinosaurs
Caltech geochemists Rob Eagle (left) and John Eiler display a dinosaur tooth, which was used to determine the body temperature of the extinct creatures.
Brachiosaurus tooth from the Jurassic Tendaguru Beds of Tanzania that was analyzed in the study by Eagle et al.
A dinosaur tooth is drilled in preparation for analyzing the isotopic concentrations in the tooth, which reveals the body temperature of the extinct creatures.
The findings suggest that these gigantopods had warmer blood then reptiles.
Brachiosaurus was one of the largest animals that walked on earth. This skeleton is exhibited at the Natural History Museum in Berlin, Germany.
