The 140 million-year-old specimen was kept in the Natural History Museum in London since its discovery in the early 1890s in Ecclesbourne Glen, near Hastings, in Sussex, England, by collector Philip James Rufford.

Now, researchers at the University of Pennsylvania School of Medicine have found that a protein called Rev-erb coordinates the daily cycles of oxygen-carrying heme molecules to maintain the body's correct metabolism.The research appears online this week in Science Express in advance of print publication in Science.
