THE extinct Order Pelycosauria contained several genera of reptiles characterized by extreme elongation of the neural spines of the vertebrae, which in life supported an area of membrane forming a “sail”1–3. Dimetrodon grandis was the end form of an evolutionary series of pelycosaurs that had tended to develop increasingly large sails2. Many suggestions have been made about the function of the sail, as camouflage among reeds while it waited for prey, for sexual display, or literally as a sail… Expand
