Nearly 400 million years ago, in the shallow rivers of what is now Antarctica, a fanged fish called Koharalepis jarviki hunted by scent and surface light — a creature poised at the threshold between aquatic and terrestrial life. Scientists at Flinders University have now read its secrets without breaking it open, using neutron tomography to illuminate a skull that compression and time had long obscured. The discovery reminds us that the story of how life first walked upon the earth is still being written, and that some of its most important chapters have been waiting, frozen, at the bottom of
