Peltandra Virginica
''Peltandra virginica'' is a plant of the arum family known as green arrow arum and tuckahoe. It is widely distributed in wetlands in the eastern United States, as well as in Quebec, Ontario, and Cuba.Whigham, Dennis F., Robert L. Simpson and Mary A. Leck. 1979. The Distribution of Seeds, Seedlings, and Established Plants of Arrow Arum (Peltandra virginica (L.) Kunth) in a Freshwater Tidal Wetland Bulletin of the Torrey Botanical Club 106: 193-199 It is common in central Florida including the Everglades and along the Gulf Coast. Its rhizomes are tolerant to low oxygen levels found in wetland soils. It can be found elsewhere in North America as an introduced species and often an invasive plant. ''P. virginica'' is a hydrophytic marshland aquatic plant pollinated by a chloropid fly through providing a brood site and releasing the pollen onto them. The primary dispersal mechanisms are via water and animals. Description This is an emergent perennial herb growing from a large rhi ...

Peltandra Primaeva
''Peltandra primaeva'' is an extinct species of monocot in the family Araceae known from a Ypresian age Eocene fossil found in western North Dakota, USA. The species was described from a single leaf specimen found at the White Butte locality, USNM number 14048. This locality is placed in the Camels Butte member of the Golden Valley Formation. The Camels Butte member outcrops at a number of sites in western North Dakota, and is designated the type locality. The holotype specimen, number ''USNM 43184'', is preserved in the National Museum of Natural History collections of the Smithsonian Institution. The single specimen was studied by paleobotanist Leo J. Hickey of the Yale University Geology Department. Hickey published the 1977 type description for ''P. primaeva'' in the Geological Society of America memoir 150, ''Stratigraphy and Paleobotany of the Golden Valley Formation (Paleogene) of Western North Dakota''. Hickey chose the specific name ''primaeva'', noting t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Golden Valley Formation
The Golden Valley Formation is a stratigraphic unit of Late Paleocene to Early Eocene age in the Williston Basin of North Dakota.Hickey, 1977 It is present in western North Dakota and was named for the city of Golden Valley by W.E. Benson and W.M. Laird in 1947.Benson, W.E. and Liard, W.M. (1947). Eocene of North Dakota. ''Geological Society of America Bulletin'', vol. 60, pp. 1166–1167.

Ypresian
In the geologic timescale the Ypresian is the oldest age (geology), age or lowest stage (stratigraphy), stratigraphic stage of the Eocene. It spans the time between , is preceded by the Thanetian Age (part of the Paleocene) and is followed by the Eocene Lutetian Age. The Ypresian is consistent with the Lower Eocene (Early Eocene). Events The Ypresian Age begins during the throes of the Paleocene–Eocene Thermal Maximum (PETM). The Fur Formation in Denmark, the Messel shales in Germany, the Oise amber of France and Cambay amber of India are of this age. The Eocene Okanagan Highlands are an uplands subtropical to temperate series of lakes from the Ypresian. The Ypresian is additionally marked by another warming event called the Early Eocene Climatic Optimum (EECO). The EECO is the longest sustained warming event in the Cenozoic record, lasting about 2–3 million years between 53 and 50 Ma. The interval is characterized by low oxygen-18 isotopes, high levels of atmospheric pCO2 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Extinct
Extinction is the termination of an organism by the death of its Endling, last member. A taxon may become Functional extinction, functionally extinct before the death of its last member if it loses the capacity to Reproduction, reproduce and recover. As a species' potential Range (biology), range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxon, Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the Fossil, fossil record) after a period of apparent absence. Over five billion species are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryotes globally, possibly many times more if microorganisms are included. Notable extinct animal species include Dinosaur, non-avian dinosaurs, Machairodontinae, saber-toothed cats, and mammoths. Through evolution, species arise through the process of specia ...
