Cover image: 240 million years ago, the eastern Tethys. In a warm and peace bay, a new life was born. It had been developed within its mother for long and now coming into the world constrained by an uncalcifed egg membrane. It was going to be a member of the Luoping Fauna at once. Unfortunately it could not break away the membrane. To be born is the death, and the death is forever. This is the rule of the nature, which makes it witness the changing of the earth and makes us know there used to be the existence of a new marine protorosaur. See details in the paper of Li Chun et al. (p. 210) (Illustrated by Chen Yu)
