The remains of two gigantic dinosaurs discovered in Australia may shed light on how dinosaurs spread across the globe. The dinosaurs are both titanosaurs , massive plant-eaters with long necks and thick limbs. The first, a new species known as Savannasaurus elliottorum , was about half the length of a basketball court and lived about 95 million years ago during the Cretaceous period. Paleontologists also found the skull of a Diamantinasaurus matildae , which grew longer than a city bus and was first identified in 2009 based on fossils in the same region as these latest finds. "These dinosaurs were co-existing happily, or so it would seem," Stephen Poropat, a paleontologist at the Australian Age of Dinosaurs Museum of Natural History in Winton, Australia, said in a video interview . The fossils may help explain how giant plant-eaters migrated across the Earth. According to researchers, the titanosaurs' features indicate they are likely descendants of dinosaur lineages that originated in
