Cordaites is an important genus of extinct gymnosperms, related to or actually representing the earliest conifers. These trees grew up to 100 ft tall and stood in both dry areas as well as wet lands. Brackish water mussels and crustacea are found frequently between the roots of these trees. Chordates fossils are most commonly found in rock sections from the Upper Carboniferous ( 323 to 299 million years ago) of Europe and the Americas.
A number of many noteworthy types from this line are:
In contrast to many other plants, fossilized Cordaites seeds are not rare, because they are rather large (up to 10 mm); those seeds are named Cordaicarpus .
Eucalyptus is a genus of more than 700 species of flowering plants in the family Myrtaceae. Most species of Eucalyptus are trees, often mallees, and a few are shrubs. Along with several other genera in the tribe Eucalypteae, including Corymbia and Angophora, they are commonly known as eucalypts. Plants in the genus Eucalyptus have bark that is either smooth, fibrous, hard or stringy, the leaves have oil glands, and the sepals and petals are fused to form a "cap" or operculum over the stamens. The fruit is a woody capsule commonly referred to as a "gumnut".
Ginkgo biloba, commonly known as ginkgo or gingko, also known as the maidenhair tree, is a species of gymnosperm tree native to East Asia. It is the last living species in the order Ginkgoales, which first appeared over 290 million years ago, and fossils very similar to the living species, belonging to the genus Ginkgo, extend back to the Middle Jurassic epoch approximately 170 million years ago. The tree was cultivated early in human history and remains commonly planted, and is widely regarded as a living fossil.
The Pinaceae, or pine family, are conifer trees or shrubs, including many of the well-known conifers of commercial importance such as cedars, firs, hemlocks, piñons, larches, pines and spruces. The family is included in the order Pinales, formerly known as Coniferales. Pinaceae are supported as monophyletic by their protein-type sieve cell plastids, pattern of proembryogeny, and lack of bioflavonoids. They are the largest extant conifer family in species diversity, with between 220 and 250 species in 11 genera, and the second-largest in geographical range, found in most of the Northern Hemisphere, with the majority of the species in temperate climates, but ranging from subarctic to tropical. The family often forms the dominant component of boreal, coastal, and montane forests. One species, Pinus merkusii, grows just south of the equator in Southeast Asia. Major centres of diversity are found in the mountains of southwest China, Mexico, central Japan, and California.
Paleobotany, also spelled as palaeobotany, is the branch of botany dealing with the recovery and identification of plant remains from geological contexts, and their use for the biological reconstruction of past environments (paleogeography), and the evolutionary history of plants, with a bearing upon the evolution of life in general. A synonym is paleophytology. It is a component of paleontology and paleobiology. The prefix palaeo- or paleo- means "ancient, old", and is derived from the Greek adjective παλαιός, palaios. Paleobotany includes the study of terrestrial plant fossils, as well as the study of prehistoric marine photoautotrophs, such as photosynthetic algae, seaweeds or kelp. A closely related field is palynology, which is the study of fossilized and extant spores and pollen.
Araucaria bidwillii, commonly known as the bunya pine (, or bunya-bunya, is a large evergreen coniferous tree in the family Araucariaceae which is endemic to Australia. Its natural range is southeast Queensland with two very small, disjunct populations in northeast Queensland's World Heritage listed Wet Tropics. There are many planted specimens on the Atherton Tableland, in New South Wales, and around the Perth metropolitan area, and it has also been widely planted in other parts of the world. They are very tall trees – the tallest living individual is in Bunya Mountains National Park and was reported by Robert Van Pelt in January 2003 to be 51.5 m in height.
The Mazon Creek fossil beds are a conservation lagerstätte found near Morris, in Grundy County, Illinois. The fossils are preserved in ironstone concretions, formed approximately 309 million years ago in the mid-Pennsylvanian epoch of the Carboniferous period. These concretions frequently preserve both hard and soft tissues of animal and plant materials, as well as many soft-bodied organisms that do not normally fossilize. The quality, quantity and diversity of fossils in the area, known since the mid-nineteenth century, make the Mazon Creek lagerstätte important to paleontologists attempting to reconstruct the paleoecology of the sites. The locality was declared a National Historic Landmark in 1997.
Taxus brevifolia, the Pacific yew or western yew, is a species of tree in the yew family Taxaceae native to the Pacific Northwest of North America. It is a small evergreen conifer, thriving in moisture and otherwise tending to take the form of a shrub.
Borassus is a genus of five species of fan palms, native to tropical regions of Africa, Asia, and Papua New Guinea.
The Rías Baixas are a series of four estuarine inlets located on the southwestern coast of Galicia, Spain. They are the Ría de Muros e Noia, the Ría de Arousa, the Ría de Pontevedra, and the Ría de Vigo. The northernmost Rías Baixas begin below Cape Finisterre while the southernmost borders the Portuguese coast, taking up the southern part of the Province of Coruña and the entire Province of Pontevedra. Its capital is the city of Pontevedra. Due to unique conditions, the Rías Baixas are rich in marine life which helps the fishing and aquaculture industry of the area. Beaches, marinas, distinctive towns, and plenty of water activities attract tourists, providing another source of income.
Rhizophora mangle, the red mangrove, is distributed in estuarine ecosystems throughout the tropics. Its viviparous "seeds", in actuality called propagules, become fully mature plants before dropping off the parent tree. These are dispersed by water until eventually embedding in the shallows.
Prenoceratops, is a genus of herbivorous ceratopsian dinosaur from the Late Cretaceous Period. It was a relatively small dinosaur, reaching 1.3 m (4.3 ft) in length and 20 kg (44 lb) in body mass. Its fossils have been found in the upper Two Medicine Formation in the present-day U.S. state of Montana, in Campanian age rock layers that have been dated to 74.3 million years ago. Fossils were also found in the Oldman Formation in the modern day Canadian province of Alberta, dating to around 77 million years ago.
Coal forests were the vast swathes of swamps and riparian forests that covered much of the land on Earth's tropical regions during the late Carboniferous (Pennsylvanian) and Permian periods. As plant matter from these forests decayed, enormous deposits of peat accumulated, which later became buried and converted into coal over the subsequent eras.
Brosimum alicastrum, commonly known as breadnut, Maya nut or ramon, and many others, is a tree species in the family Moraceae of flowering plants, whose other genera include figs and mulberries. The plant is known by a range of names in indigenous Mesoamerican and other languages, including: ojoche, ojite, ojushte, ujushte, ujuxte, capomo, mojo, ox, iximche, masica in Honduras, uje in the state of Michoacan Mexico, mojote in Jalisco, chokogou in Haitian Creole and chataigne in Trinidadian Creole. In the Caribbean coast of Colombia it is called guaímaro or guaymaro.
The pygmy treeshrew is a treeshrew species within the family Tupaiidae. It is native to Thailand, Malaysia and Indonesia. The generic name is derived from the Malay word tupai meaning squirrel or small animals that resemble squirrels.
Thadou or Thado Chin is a Sino-Tibetan language of the Northern Kuki-Chin-Mizo sub-branch. It is spoken by the Thadou people in Northeast India And bordering Myanmar. The speakers of this language use Meitei language as their second language (L2) according to the Ethnologue.
This article attempts to place key plant innovations in a geological context. It concerns itself only with novel adaptations and events that had a major ecological significance, not those that are of solely anthropological interest. The timeline displays a graphical representation of the adaptations; the text attempts to explain the nature and robustness of the evidence.
Fossil Fools Day is an environmental demonstration day. It occurs on April 1. The name is a play on the term fossil fuels and April Fools' Day.
Stylemys is the first fossil genus of dry land tortoise belonging to the order Testudines discovered in the United States. The genus lived in temperate to subtropical areas of North America, Europe, and Asia, based on fossil distribution. The genus was first described in 1851 by Joseph Leidy. The tortoise was common in the prehistoric Badlands, especially Nebraska and South Dakota. The species has also been found in the formations in and around Badlands National Park. Fossil fragments have also been found in the Palm Park Formation of New Mexico.
The New Guinea mangroves is a mangrove ecoregion that covers extensive areas of the coastline New Guinea, the large island in the western Pacific Ocean north of Australia.
The forest dormouse is a species of rodent in the family Gliridae found in eastern Europe, the Balkans and parts of western Central Asia. It is categorized as being of least concern in the IUCN List of Threatened Species due to its wide range and stable population trend. Forest dormice have a diploid count (2n) of 48 chromosomes. Even though this species lives in a variety of geographic locations, its greatest population density is in the forests of central Moldova, in Transcaucasia, and in the mountains of Central Asia. In most other locations, population density of this species is rather low. Population density is dependent on many factors. But the main features that this species depends on for choosing a location are the presence of the appropriate food sources as well as good foliage that can be used for a habitat. The reason why the forests in central Moldova have the highest population density is they provide the largest diversity of food sources which are available throughout the year. This location also provides the best type of foliage for the forest dormice to build their nests as well as swing from branches. The combination of both of these aspects allows for this species to have its highest needs met. Therefore, during mating season they produce offspring who also stay in the same general area when they mature. It makes sense not to move from an area if it is providing for your most basic needs.
