Eldorado Posted June 17, 2021 #1 Share Posted June 17, 2021 "As my colleagues and I now report in Proceedings of the Royal Society B, Ophiojura does indeed represent a totally unique and previously undescribed type of animal. It is one of a kind – the last known species of an ancient lineage, like the coelacanth or the tuatara. "We compared DNA from a range of different marine species, and concluded that Ophiojura is separated from its nearest living brittle star relatives by about 180 million years of evolution. This means their most recent common ancestor lived during the Triassic or early Jurassic period, when dinosaurs were just getting going."
