Study revises 'living fossil' fish anatomy, reshaping view of vertebrate skull evolution

The coelacanth is known as a "living fossil" because its anatomy has changed little in the last 65 million years. Despite being one of the most studied fish in history, it continues to reveal new information that could transform our understanding of vertebrate evolution. This is revealed in a study published in the journal Science Advances by researchers from the University of São Paulo (USP) in Brazil and the Smithsonian Institution in the United States.
