经过高级成像,将章鱼化石重新归类为状相对物. Octopus fossil reclassified as nautiloid relative after advanced imaging.

曾经被认为是世界上最古老的章鱼化石, 它已在先进的成像显示它有11根牙而不是七个或九个典型的章魚之后重新归类为一个螺旋状的亲戚. A fossil once thought to be the world's oldest octopus from 300 million years ago has been reclassified as a nautiloid relative after advanced imaging revealed it has 11 radula teeth instead of the seven or nine typical of octopuses. 这一发现发表在"皇家学会B期刊"上, 表明章鱼的进化时间比以前所认为要晚得多, 并推翻了状动物软组织保存记录. The discovery, published in Proceedings of the Royal Society B, suggests octopuses evolved much later than previously believed and pushes back the record for soft tissue preservation of nautiloids.
