More than 1,200 years ago, elephant birds roamed the island of Madagascar. While these ostrich-like giants are now extinct, new research from ÃÛÌÇÖ±²¥ Boulder and Curtin University in Australia reveals that their eggshell remnants hold valuable clues about their time on Earth. Published today in Nature Communications, the study describes the discovery of a previously unknown, separate lineage of elephant bird that roamed the wet, forested landscapes on the northeastern side of Madagascar—a discovery made without access to any skeletal remains.
