Together, they have solved a mystery some 500 million years in the making.

Smith and Caron have been giving a makeover to an enigmatic creature called Nectocaris . Until recently, only one specimen had ever been found. Its poor state and puzzling combination of features made it nigh impossible to classify. But not anymore – by finding a staggering 91 extra specimens, Smith and Caron have revealed that Nectocaris is the earliest known cephalopod. It’s the great-great-great-(etc)-granduncle of today’s octopuses, squids and cuttlefish.

Nectocaris pteryx or “swimming crab with wings” was first described by Simon Conway Morris in 1976. It’s one of the stars of Canada’s Burgess Shale formation, arguably the planet’s most important collection of fossils.
