Origin and radiation of squids revealed by digital fossil-mining

Joint press release (in Japanese) by Hokkaido University, and Japan Synchrotron Radiation Research Institute (JASRI)

Abstract
The evolution of soft-bodied squids, which provide a major part of the biomass in modern oceans globally, is poorly understood owing to their patchy fossil record. We provide a comprehensive evolutionary history of squids through “digital fossil-mining” techniques, revealing a new lagerstätte. The more than 250 fossil beaks of 40 species show that squids originated and rapidly radiated by 100 million years ago. Our data suggest that ……
