An assemblage of 46 fossil pollen and spore types is described from a core drilled through the middle Eocene Saramaguaca´n Formation, Camagu¨ey Province, eastern Cuba.

Many of the specimens represent unidentified or extinct taxa but several can be identified. The early Eocene is characterized by a middle Eocene fossil plant assemblage book phase, even at high latitudes. The CO 2 level ranged from to ppm due to the increase in volcanic activity.

The climate dynamics of the Indian subcontinent and biotic exchange between the neighboring continents can be traced by studying the Eocene fossil assemblages which are nicely preserved in the rock records.

Algae are represented by abundant remains of Characeae, including both vegetative fragments and gyrogonites. Fossil remains of the family Trochodendraceae are found in the early middle Eocene ( Ma) Republic flora of northeastern Washington, a flora that contains a highly diverse and extensive montane warm-temperate assemblage.

The conifer genus Araucaria, distributed worldwide during the Mesozoic, has a disjunct extant distribution between South America and s assigned to Australasian Araucaria Sect.

The Phosphorites are composed mostly of phosphate-rich clays, including fossil materials, that fill the caves and fissures riddling the karstic landscape in the large regional Quercy area (including parts of.

About this book. Language: English. The oil shale of the Middle Eocene Messel Formation as exposed in the Messel Pit near Darmstadt, Hessen, Germany, is a famous and widely known source for extremely well preserved fossils documenting a wealth of terrestrial biota.

The palynological assemblages suggest that the middle Eocene vegetation in southern China was composed of mixed evergreen and deciduous broad-leaved forests, accompanied by abundant subtropical to tropical evergreen taxa, thus bearing strong resemblance to the modern vegetation in southern China, and indicating a warm-humid subtropical climate.

Selected fossil plant taxa. Credit: SU Tao highly diverse fossil assemblage from the current and represent a middle Eocene (about 47 million years ago) humid subtropical ecosystem. A Middle Eocene Fossil Plant Assemblage (Powers Clay Pit) from Western Tennessee.

Hall, Review of Palaeobotany and Palynology, (): The origins and development of the arid and highly seasonal steppe-desert biome in Central Asia, the largest of its kind in the world, remain largely unconstrained by existing records.

It is unclear how Cenozoic climatic, geological, and biological forces, acting at diverse spatial and temporal scales, shaped Central Asian ecosystems through time. The first published mention of fossils at McAbee was Wilson’s () treatment of Middle Eocene fish from British Columbia.

In this report, we will describe the flora found at McAbee based on data from both mega- fossils and pollen. From that information we may infer the floral structure and paleoecology of the late Early Eocene McAbee forest. The early Eocene Fossil Lake plant assemblage includes many tropical and subtropical plant taxa, and the leaf size is relatively large (Grande ).

In contrast, the late Eocene Florissant assemblage includes many more taxa of warm temperate climates, and the leaf size is considerably smaller. The 70 plant fossil taxa so far recovered include the first occurrences of several modern Asian lineages and represent a middle Eocene (about 47.

The Paleocene epoch is the 10 million year time interval directly after the K–Pg extinction event, which ended the Cretaceous Period and the Mesozoic Era, and initiated the Cenozoic Era and the Paleogene period. It is divided into three ages: the Danian spanning 66 to million years ago (mya), the Selandian spanning to mya, and the Thanetian spanning to 56 mya.

Late Eocene fossil plants of the John Day Formation and present in the middle Eocene floras of the underlying Clarno Formation, Mountain assemblage) of the Bridge Creek flora of the John Day Formation. Figure 2. Students working at the Whitecap Knoll shale locality, with White. At this time, the Earth’s climate was transitioning from the global warmth of the late Palaeocene/early Eocene to cooler conditions and ice sheet growth beginning at the end of the Eocene but was also variable, with periods of warming (middle Eocene Climate Optimum, from to 40 Mya) superimposed on the general cooling trend (Baatsen et al.

2 days ago  Researchers discovered a rich assemblage of plant fossils in the Bango Basin of central Tibet. Photo by Tao Su but also allow us to constrain the middle Eocene.

The Clarno Nut Beds flora is predominantly made up of angiosperms (flowering plants) like magnolias, walnuts, kiwi, bananas and others. The beds also contain gymnosperms (produces seeds without fruit) like Gingko sp., Yews, and more.

The Nut Beds also preserve over 66 genera and 77 species of petrified woods, making it the most species rich fossil wood locality on Earth of any age. Fossils from the Eocene of South Australia and Western Australia and the Oligo–Miocene of Victoria represent the first known Australian leaf fossils of subfamily Persoonioideae, tribe Persoonieae.

Persoonieaephyllum blackburnii sp. nov. is described from Middle Eocene Nelly Creek sediments near Lake Eyre, South Australia. Persoonieae are an important clade for understanding vegetation. Eocene lakebed sediments at Stonerose Interpretive Center in Republic, Washington, USA are one of the most important Cenozoic fossil sites in North America, having gained international attention because of the abundance and diversity of plant, insect, and fish fossils.

This report describes the first detailed geologic investigation of this unusual lagerstätten. “These fossils not only record the diverse composition of the ancient Tibetan biota, but also allow us to constrain the middle Eocene land surface height in central Tibet to 1, ± m, and quantify the prevailing thermal and hydrological regime,” said Prof.

ZHOU Zhekun of XTBG. The Eocene Landscape — The Buckeye Diggings fossil plant assemblage is just a subset of what has become known as the regional Chalk Bluffs flora described by Harry MacGinitie in Like the Buckeye Diggings assemblage, the Chalk Bluff plants were deposited in floodplain sediments associated with the ancestral Yuba River drainage system that were later exposed through the.

Late Middle Eocene time marks one of the most dynamic periods of the Paleogene in the western interior of North America. Analysis of an extensive, new collection of plant, invertebrate, and vertebrae fossils from the Uinta Formation in the Uinta Basin, south of Myton, Utah, USA, provides evidence of environmental change.

Paleobotanical specimens are preserved in late stage Uinta Lake sediments. The McAbee Fossil Beds is a Heritage Site that protects an Eocene Epoch fossil locality east of Cache Creek, British Columbia, Canada, just north of and visible from Provincial Highway 97 / the Trans-Canada Highway at The McAbee Fossil Beds, comprising hectares (1, acres), were officially designated a Provincial Heritage Site under British Columbia's Heritage Conservation Act on.

Tertiary Research, assigned to the early Middle Eocene or older (Gradstein et al., ). The K-Ar ages obtained in this study are similar to that of the plant megafossil assemblage of Río Pichileufú in Argentina (e.g., Berry, ; 41°7’S) recently dated as ± Ma by the 40Ar/ 39Ar method (Wilf et al., ).

The Río Pichileufú assemblage has. Laki (Early Eocene) age mainly on the basis of its correla-tion with the coal-bearing formations in Baluchistan, Pakistan (La Touche ; Vredenburg ). Varied plant remains have been known from the Palana Forma-tion for a long time but no animal fossils were recovered from it until recently.

The early reports of floral remains. Remains of over 30 plant taxa have been described in detail, along with a diverse assemblage of fungi that document a variety of ecological interactions with plants. As a flora of the Okanagan Highlands, the Princeton chert plants are an assemblage of higher elevation taxa of the latest early to earliest middle Eocene, with some components.

Fossil remains of the family Trochodendraceae are found in the early middle Eocene (49–50 Ma) Republic flora of northeastern Washington, a flora that contains a highly diverse and extensive montanewarm-temperate assemblage.
