Valanginian
In the geologic timescale, the Valanginian is an age or stage of the Early or Lower Cretaceous. It spans between 139.8 ± 3.0 Ma and 132.9 ± 2.0 Ma (million years ago). The Valanginian Stage succeeds the Berriasian Stage of the Lower Cretaceous and precedes the Hauterivian Stage of the Lower Cretaceous. Stratigraphic definitions The Valanginian was first described and named by Édouard Desor in 1853. It is named after Valangin, a small town north of Neuchâtel in the Jura Mountains of Switzerland. The base of the Valanginian is at the first appearance of calpionellid species '' Calpionellites darderi'' in the stratigraphic column. A global reference section (a GSSP) had in 2009 not yet been appointed. The top of the Valanginian (the base of the Hauterivian) is at the first appearance of the ammonite genus '' Acanthodiscus''. Subdivision The Valanginian is often subdivided in Lower and Upper substages. The Upper substage begins at the first appearance of ammonite speci ...

Cretaceous
The Cretaceous ( ) is a geological period that lasted from about 145 to 66 million years ago (Mya). It is the third and final period of the Mesozoic Era, as well as the longest. At around 79 million years, it is the longest geological period of the entire Phanerozoic. The name is derived from the Latin ''creta'', " chalk", which is abundant in the latter half of the period. It is usually abbreviated K, for its German translation ''Kreide''. The Cretaceous was a period with a relatively warm climate, resulting in high eustatic sea levels that created numerous shallow inland seas. These oceans and seas were populated with now-extinct marine reptiles, ammonites, and rudists, while dinosaurs continued to dominate on land. The world was ice free, and forests extended to the poles. During this time, new groups of mammals and birds appeared. During the Early Cretaceous, flowering plants appeared and began to rapidly diversify, becoming the dominant group of plants across the Ear ...

Chresmoda
''Chresmoda'' is an extinct genus of insects within the family Chresmodidae. Description ''Chresmoda'' are large enigmatic insects with very long specialized legs, probably adapted for skating on the water surface similar to pond skaters. They can reach a body length of about , with a forewing length of about . Some lagre specimens could reached a size of about . These Polyneoptera of uncertain position have been considered aquatic and living on the water surface, probably predaceous on nektonic small animals. They lived during the Cretaceous of Brazil, China, Lebanon, Spain, United Kingdom, Mongolia and Myanmar, as well as in the Late Jurassic of Germany, from 150.8 to 94.3 Ma from the Tithonian to the Cenomanian ages. While most species are known from compression fossils, ''Chresmoda chikuni'' is known from well preserved 3-dimensional specimens in amber.
