Modest insect-munching Madagascar reptile was forerunner to dinosaurs

Dinosaurs and the flying reptiles called pterosaurs - both known for achieving great size - had humble beginnings, as shown by a diminutive insect-eating reptile from Madagascar that was a forerunner and close relative of both groups. Scientists on Monday described fossils of a Triassic Period creature, called Kongonaphon kely, that measured about 16 inches (40 cm) long and stood four inches (10 cm) tall at the hip. It inhabited a floodplain region of what is now southwestern Madagascar about 237 million years ago.
