revealed by a new Ordovician stem aculiferan, by Jakob Vinther, Luke Parry, Derek Briggs and Peter Van Roy.

“I would say that our animal probably is very close to the spitting image of how the ancestor of all molluscs must have looked like 530 million years ago,” said Jakob Vinther, a molecular palaeobiologist from the University of Bristol and co-author of the research published in the journal Nature.
