Danaea is the basal lineage in the Marattiaceae and the oldest fossils are from the Paleocene, a period where rainforests became more abundant.
Fossils of Fedaiella are found in the marine strata of the Quaternary of Japan, Paleocene of Poland and Triassic of Italy.
The Cayman Rise extends from southeastern Cuba along the northern margin of the Cayman Trough toward Costa Rica and resulted from Paleocene to Eocene island arc formation with associated volcanism along an extinct subduction zone.
It declined in diversity as the Cretaceous progressed with the extinction of species such as Ginkgo huolinhensis, and by the Palaeocene, only a few Ginkgo species, Ginkgo cranei and Ginkgo adiantoides, remained in the Northern Hemisphere, while a markedly different (and poorly documented) form persisted in the Southern Hemisphere.
It contains only one species, Prohepialus incertus, which was described from a Thanetian crater lake diatomite (Paleocene) in Menat (Puy-de-Dôme), France.
Fossil pollen assigned to the genus has been recognized from the Palaeocene - Eocene boundary.
The Willwood Formation is a sedimentary sequence deposited during the late Paleocene to early Eocene.
From there, this family evolved into a wide variety of genera, including Arctocyon (known as/similar to Claenodon in North America), Arctocyonides, Landenodon, and Mentoclaenodon, found in the late Paleocene layers of Cernay, France.
Berruornis orbisantiqui was an early fossil owl or owl-like bird recovered from late Paleocene deposits in the region of Reims in northeastern France.
Remains of the species Cernaysia manueli (Vianey-Liaud M. 1986) were found in Upper Paleocene strata from Cernay, France.
The order originated in South America during the Paleocene, and due to the continent's former isolation remained confined to it during most of the Cenozoic.
Although the species's position within the genus Corydoras is tentative and unresolved, its anatomy confirms that it is a member of the subfamily, Corydoradinae, and demonstrates that the callichthyids had already diverging or diversifying before the end of the Paleocene.
•
Corydoras revelatus is an extinct species of callichthyid known from a single specimen found in Late Paleocene strata of the Mais Gordo Formation in Salta, Argentina.
The fossil range of the group may extend back into the Paleocene depending on whether or not remains of an alligatoroid from Berru, France belong to a diplocynodontine.
Eupterornis from the Paleocene of Châlons-sur-Vesle (France) has some features reminiscent of loons, but others seem more similar to Charadriiformes such as gulls (Laridae).
The most important formations are the Cretaceous chalks, which are exposed as the high ground in the north and west of the county, and the Cenozoic rocks made up of the Paleocene age Reading beds and Eocene age London Clay that occupies the remaining southern part.
The age of the sequence ranges from Cenomanian through to Campanian, The upper boundary is an unconformity across which rocks of Maastrichtian to Paleocene age are missing.
The species is known only from the Early Paleocene, Danian stage Rasstrigin 2 locality, Dubovsky District, Volgograd Oblast, Russia.
The Paleocene bird Scaniornis was described from fossil bones aged some 60 million years or more, which were found in the Limnhamn limestone; it was apparently a waterbird and might have been an early flamingo relative.
They were once viewed as primitive carnivores, like the Paleocene family Arctocyonidae, and their diet probably included meat and fish.
Whether they only occurred during the long-term warming, and whether they are causally related to apparently similar events in older intervals of the geological record (e.g. the Toarcian turnover of the Jurassic) are open issues.
His research focus is in vertebrate paleontology, especially the Paleocene-Eocene transition and early Cenozoic mammals.
With its enigmatic position at the base of this radiation, Radinskya is a member of the Chinese Paleocene fauna which includes primitive tethytheres such as Minchenella and the oldest arsinoitheres; it shares many characters with perissodactyls and some with phenacolophids, but is to primitive to be called either a horse, a rhino, or a tapir.
