Three hundred and fifty million years before anyone thought to ask the question, a predatory fish in what is now Nova Scotia was quietly solving the problem of how to eat in a changing world. A curved jaw discovered in a creek in 2015 and studied for nearly a decade has introduced science to Sphyragnathus tyche — a previously unknown species whose specialized teeth suggest that ray-finned fish diversified by reinventing their mouths before they reinvented their movements. The find offers a rare window into the moment when the modern vertebrate world was still being negotiated, and reminds us t
