A recent study reveals that "Berenicea", a group of cyclostome bryozoans, has continuously decreased in zooid size over the past 200 million years, showing an evolutionary trend opposite to "Cope's Rule". This research was completed through collaboration between MA Junye from the Nanjing Institute of Geology and Paleontology, Chinese Academy of Sciences (NIGPAS), Lee Hsiang Liow from the University of Oslo, Norway, and Paul D. Taylor from the Natural History Museum, London, UK, and was published in the international academic journal Palaeontology.
