Caption

Like most early nocturnal mammals, Rugosodon eurasiaticus was active at night. This reconstruction shows Rugosodon searching for food among ferns and cycads on the lake shores in the darkness. This image relates to a paper that appeared in the 16 August, 2013, issue of Science, published by AAAS. The paper, by Chong-Xi Yuan at the Chinese Academy of Geological Sciences in Beijing, China, and colleagues was titled, "Earliest Evolution of Multituberculate Mammals Revealed by a New Jurassic Fossil."
