Lystrosaurus is back in headlines after a fossil skull fragment rewrites early evolution timelines and new evidence ties it to surviving the Great Dying. Tiny, plant-eater dicynodont from late Permian–early Triassic.
Scientists have identified fossilized eggs of a 250-million-year-old therapsid, showing these ancestors of mammals laid eggs. Using advanced imaging, they revealed the embryo inside a soft eggshell, shedding light on early reproductive strategies and survival tactics of prehistoric animals. This discovery confirms therapsids' oviparity and enhances understanding of mammalian evolution.
