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.
Taxodium / t æ k ˈ s oʊ d i ə m / [1] is a genus of one to three species (depending on taxonomic opinion) of extremely flood-tolerant conifers in the cypress family, Cupressaceae.The name is derived from the Latin word taxus, meaning "yew", and the Greek word εἶδος (eidos), meaning "similar to."
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.

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. [7] [8]
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]
