Résumé :	The dinosaur Sinosauropteryx, thought by some to have given rise to birds, is from the Chinese Jehol biota. A specimen of the dinosaur uniquely shows the opisthotonic process (sharp upward recurvatures of neck and tail) occurring in three stages in the tail, evident by a trail of associated material. This evidence, together with the rufous colour of the specimen, is particularly pertinent in the light of a recent hypothesis that the Jehol biota included victims of volcanic eruptions (as, e.g., skeletons at Pompeii and Herculaneum), which had perished from pyroclastic surges and scorching temperatures.
