The Opisthotonic death pose is a death pose widely observed in dinosaur fossils where the head is thrown back and tails are arched upward that Creationists (Creation Ministries International, Answers in Genesis) have attributed to a global Flood.[1] Scientists confirmed the role of water in the fossilization process by experimenting on both chickens[2] and emus[3] to confirm that the same pose results from asphyxiation during a water burial.
