In geology , Neocomian was a name given to the lowest stage of the Cretaceous system. It was introduced by Jules Thurmann in 1835 on account of the development of these rocks at Neuch tel Neocomum , Switzerland. It has been employed in more than one sense. In the type area the rocks have been divided into two sub stages, a lower, Valanginian from Valengin, E. Desor, 1854 and an upper, Hauterivian from Elauterive, E. Renevier, 1874 there is also another local sub stage, the infra Valanginian or Berriasian from Berrias, H. Coquand, 1876 . These three sub stages constitute the Neocomian in its restricted sense. A. von Koenen and other German geologists extend the use of the term to include the whole of the Lower Cretaceous up to the top of the Gault or Albian . Eug ne Renevier divided the Lower Cretaceous into the Neocomian division, embracing the three sub stages mentioned above, and an Urgonian division, including the Barremian, Rhodanian and Aptian sub stages. Sir Archibald Geikie A. Geikie Text Book of Geology , 4th ed., 1903 regards Neocomian as synonymous with Lower Cretaceous, and he, like Renevier, closes this portion of the system at the top of the Lower Greensand Aptian . Other British geologists Alfred John Jukes Brown A. J. Jukes Browne , &c. restrict the Neocomian to the marine beds of Speeton and Tealby, and their estuarine equivalents, the Weald Clay and Hastings Sands Wealden . Much confusion would be avoided by dropping the term Neocomian entirely and employing instead, for the type area, the sub divisions given above. This becomes the more obvious when it is pointed out that the Berriasian type is limited to Dauphine the Valanginian has not a much wider range and the Hauterivian does not extend north of the Paris basin. Characteristic fossils of the Berriasian are Hoplites euthymi, H. occitanicus of the Valanginian, Nalica leviathan, Bel mnites pistilliformis and B. dilatatus, Oxynoticeras Gevrili of the Hauterivian, Hoplites radiatus, Cr ioceras capr ... more details

The genus Albionbaatar was named by Kielan Jaworowska Z. and Ensom P.C. in 1994 based on a single species. Albion refers to England, while, baatar is Mongolian language Mongolian , meaning hero . This is due to a recent nomenclatural tradition among specialists who study this group. Many multituberculates are called something baatar, regardless of where they come from. This is in part because the best preserved remains of multis tend to come from the Upper Cretaceous of the Gobi desert.
