Botanist Dr Clement Coiffard of the Museum für Naturkunde Berlin discovered the oldest, completely preserved lily in the research collection: Cratolirion bognerianum was found in calcareous sediments of a former freshwater lake in Crato in northeastern Brazil. With an age of about 115 million years, Cratolirion is one of the oldest known monocotyledonous plants. These include orchids, sweet grasses, lilies and lilies of the valley. Cratolirion is extraordinarily well preserved, with all roots, the flower and even the individual cells are fossilised. With a length of almost 40 centimetres, the specimen is not only extremely huge, but also shows almost all the typical characteristics of monocotyledonous plants.
