But throughout history, bigger is not always better. It's still a mystery as to why these early dinosaurs even survived the volcanism, let alone thrived, Whiteside said, "It's really that it was just a fortuitous combination of traits that they unwittingly possessed that let them get through the catastrophic climate change that their competitors didn't have.". Whiteside and her colleagues specifically looked at the ratio of two carbon isotopes, or atoms of the same element that have a different number of neutrons, in the wax of ancient leaves and wood found in lake sediments mixed with volcanic material called basalts. It took decades for this idea to catch on, particularly with paleontologists, but most now seem to have finally come around to it.
