Cestoda, commonly known as tapeworms, is a large class within the platyhelminth phylum with about 5,000 species described so far. Recently, researchers from the Nanjing Institute of Geology and Paleontology of the Chinese Academy of Sciences (NIGPAS), in collaboration with scientists from Yunnan University, Germany, the U.K., and Myanmar, have reported an enigmatic fossil from mid-Cretaceous Kachin amber, dating to about 100 million years ago.
