Cretevania Montoyai
''Cretevania'' is an extinct genus of Evaniidae, which lived in what is now China, Burma, England, Lebanon, Mongolia, Russia and Spain during the Cretaceous period. the genus was described by Rasnitsyn in 1975, and the type species is ''Cretevania minor''.

Animalia
Animals are multicellular, eukaryotic organisms in the biological kingdom Animalia. With few exceptions, animals consume organic material, breathe oxygen, are able to move, can reproduce sexually, and go through an ontogenetic stage in which their body consists of a hollow sphere of cells, the blastula, during embryonic development. Over 1.5 million living animal species have been described—of which around 1 million are insects—but it has been estimated there are over 7 million animal species in total. Animals range in length from to . They have complex interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as zoology. Most living animal species are in Bilateria, a clade whose members have a bilaterally symmetric body plan. The Bilateria include the protostomes, containing animals such as nematodes, arthropods, flatworms, annelids and molluscs, and the deuterostomes, containing the echinode ...

Flora Plants Fungi Cnidarians Research * New three dimensionally phosphatized microfossils of coronate scyphozoan '' Qinscyphus necopinus'', including a new type of fossil embryo, are described from the Cambrian (Fortunian) Kuanchuanpu Formation (China) by Shao ''et al.'' (2018), who interpret their findings as indicating that ''Qinscyphus'' underwent direct development. * A study on the morphology of the conulariid species '' Carinachites spinatus'' based on a new specimen collected from the lower Cambrian Kuanchuanpu Formation (China) is published by Han ''et al.'' (2018). * Revision of stony corals from the Lower Cretaceous (Berriasian) Oehrli Formation (Austria and Switzerland) is published by Baron-Szabo (2018), who compares this fauna with five additional Berriasian coral faunas.
