Could global warming lead to 10ft reptiles? Scientists say small plant-eating lizards could grow to the size of Komodo dragons
Fossils of a giant lizard discovered in Burma have led scientists to believe a rise in temperature 40 million years ago caused plant-eating lizards to grow to the size of the 10ft dragons.
Scientists previously thought that large meat-eating dragons grew larger than their herbivore cousins because of a lack of predators.
These findings now from from the University of California and University of Nebraska-Lincoln suggest that a warmer climate is needed for large lizards to grow – and that global warming could cause this to happen again.
