Today In History: Nicolaus Steno
From Today In Science History
:In 1667, a classic paleontological paper by Nicolaus Steno was published by the Royal Society, London. His topic, Head of a shark dissected, represented the first such scientific paper to recognise that fossils were the remains of creatures who had died and subsequently had become petrified. Controversy resulted. The same claim had been made in the time of the ancient Greeks, two millennia earlier.
