By the Late Cretaceous, a temperate climate in both the Northern and Southern hemisphere was ideal for the rapid diversification and distribution of various angiosperms and to a lesser extent, conifers. Studies on the mid-Cretaceous paleorecord conclude that forest compositions in Northern hemisphere high paleolatitudes were mainly populated by ...
Podozamites is an extinct genus of fossil conifer leaves. In its broader sense, it has been used as a morphogenus ( form taxon ) to refer to any broad leaved multi-veined conifer leaves. Modern broad-leaved conifers with a similar form include Agathis in the family Araucariaceae and Nageia in Podocarpaceae , with some Podozamites sensu lato ...
The Hell Creek Formation was a low floodplain at the time before the sea retreated, and in the wet ground of the dense woodland, the diversity of angiosperms and conifers were present. An endless diversity of herbaceous flowering plants, ferns and moss grew in the forest understory.
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.
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.
Araucariaceae is a family of conifers with three living genera, Araucaria, Agathis, and Wollemia.While the family's native distribution is now largely confined to the Southern Hemisphere, except for a few species of Agathis in Malesia, it was formerly widespread in the Northern Hemisphere during the Jurassic and Cretaceous periods.
Glyptostrobus is a small genus of conifers in the family Cupressaceae (formerly in the family Taxodiaceae).The sole living species, Glyptostrobus pensilis, is native to subtropical southeastern China, from Fujian west to southeast Yunnan, and also very locally in northern Vietnam and Bolikhamsai province of eastern Laos near the Vietnam border.
Geinitzia is an extinct genus of conifers, with an uncertain position within the group. [1] Species belonging to the genus lived in the late Cretaceous and have been found in Argentina [2] and Europe. [3] [4]
