Along with the hadrosaur mentioned above, there have been several discoveries of dinosaurs in Antarctica. For example, a 12-foot-(4-meter-) long, bipedal, plant-eating iguanodontid was discovered in February 1999 on a rocky beach of James Ross Island. A 70-million-year-old bipedal, meat-eating dinosaur (an unnamed theropod) was also discovered on James Ross Island in late 2003. The discoveries included a lower leg and foot bones, fragments of the upper jaw, and some teeth. Still another dinosaur, a 200-million-year-old bipedal, long-necked, plant-eating, unnamed sauropod was discovered in 2003 in the Antarctic interior, including fossils of a pelvis and one of the dinosaur’s hipbones.
