In the early Cretaceous, approximately 130 million years ago, there was a major diversification of angiosperms that set in motion a large evolutionary change in high paleolatitude forest composition. The diversification of angiosperms is in close connection with pollen and nectar collecting insects.
Pagiophyllum is a form genus of fossil coniferous plant foliage. Plants of the genus have been variously assigned to several different conifer groups including Araucariaceae and Cheirolepidiaceae. [1] They were found around the globe during the Carboniferous to the Cretaceous period. [2] [3]
Pararaucaria is a genus of conifer cone belonging to the extinct family Cheirolepidiaceae. Fossils are known from the Lower Jurassic to Early Cretaceous of North America, Europe, South America and Asia. It is associated with Brachyphyllum-type foliage.
Voltziales is an extinct order of conifers.The group contains the ancestral lineages from which modern conifer groups emerged. Voltzialean conifers are divided into two informal groups, the primitive "walchian conifers" like Walchia, where the ovuliferous cone is composed of radial shoots and the more advanced "voltzian voltziales", also known as "transitional conifers" where the cone is ...
Cheirolepidiaceae (also spelled Cheirolepidaceae) is an extinct family of conifers.They first appeared in the Triassic, and were a diverse and common group of conifers during most of the Mesozoic era, primarily at low latitudes, [1] where they often formed a dominant element of the vegetation. [2]
The terrestrial environment surrounding the deposition area is thought to have been a temperate polar forest, including podocarp and araucarian conifers, as well as Nothofagus. [ 5 ] [ 6 ] Most of the fossilized woods and flowers discovered on Seymour Islands consist of extinct species of conifer trees and lilies during warm climate.
Black Forest, Germany. With deep woods, quaint villages, and a hazy, mystical wonder, the Black Forest looks like a fairy tale come to life and inspired some of most beloved stories from the ...
Araucaria (/ æ r ɔː ˈ k ɛər i ə /; original pronunciation: [a.ɾawˈka.ɾja]) [2] is a genus of evergreen coniferous trees in the family Araucariaceae.While today they are largely confined to the Southern Hemisphere, during the Jurassic and Cretaceous they were globally distributed.
