Alexander Emmanuel Rodolphe Agassiz, son of Louis Agassiz and stepson of Elizabeth Cabot Agassiz, was an American scientist and engineer.
Paleobotany, which is 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- 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.
André Marie Constant Duméril was a French zoologist. He was professor of anatomy at the Muséum national d'histoire naturelle from 1801 to 1812, when he became professor of herpetology and ichthyology. His son Auguste Duméril was also a zoologist.
Vachellia farnesiana, also known as Acacia farnesiana, and previously Mimosa farnesiana, commonly known as sweet acacia, huisache, or needle bush, is a species of shrub or small tree in the legume family, Fabaceae. It is deciduous over part of its range, but evergreen in most locales. The species grows to a height of 15–30 feet (4.6–9.1 m) and grows multiple trunks. The base of each leaf is accompanied by a pair of thorns on the branch. Its flowers are used in the perfume industry.
The Museum of Comparative Zoology, full name the Louis Agassiz Museum of Comparative Zoology, often abbreviated simply to MCZ, is a zoology museum located on the grounds of Harvard University in Cambridge, Massachusetts. It is one of three natural-history research museums at Harvard, whose public face is the Harvard Museum of Natural History. Harvard MCZ's collections consist of some 21 million specimens, of which several thousand are on rotating display at the public museum. The current director of the MCZ is James Hanken, the Louis Agassiz Professor of Zoology at Harvard.
Craugastor rugosus is a species of rain frog in the family Craugastoridae. It is found in Costa Rica and southwestern Panama, and possibly southern Nicaragua.
Echinerpeton is an extinct genus of synapsid, including the single species Echinerpeton intermedium from the Late Carboniferous of Nova Scotia, Canada. The name means 'spiny lizard' (Greek). Along with its contemporary Archaeothyris, Echinerpeton is the oldest known synapsid, having lived around 308 million years ago. It is known from six small, fragmentary fossils, which were found in an outcrop of the Morien Group near the town of Florence. The most complete specimen preserves articulated vertebrae with high neural spines, indicating that Echinerpeton was a sail-backed synapsid like the better known Dimetrodon, Sphenacodon, and Edaphosaurus. However, the relationship of Echinerpeton to these other forms is unclear, and its phylogenetic placement among basal synapsids remains uncertain.
Tranodis is an extinct genus of prehistoric sarcopterygians or lobe-finned fish. It was a lungfish from the Upper Mississippian of North America.
Kayentachelys is an extinct genus of turtle known only from the "silty facies" of the Lower Jurassic Kayenta Formation in northeastern Arizona on the lands of the Navajo Nation.
Acromyrmex nigrosetosus is a species of leaf-cutter ant, a New World ant of the subfamily Myrmicinae of the genus Acromyrmex. This species is from one of the two genera of advanced attines within the tribe Attini.
Asaphidae is a family of asaphid trilobites. Although the first genera originate in Upper Cambrian marine strata, the family becomes the most widely distributed and most species-rich trilobite family during the Ordovician. 754 species assigned to 146 genera are included in Asaphidae.
Elizabeth Bangs Bryant was an American arachnologist. She worked at the Museum of Comparative Zoology in Cambridge, Massachusetts and was a close acquaintance of James Henry Emerton. She is best known for her studies of the spiders of New England and the Caribbean.
Matoniaceae is one of the three families of ferns in the Gleicheniales order of the Polypodiopsida class. Fossil records reveal that Matoniaceae ferns were abundant during the Mesozoic era, during which they lived on every continent, including Antarctica, with eight genera and 26 species, with the oldest known specimens being from the Middle Triassic of Antarctica. Today the family is much less abundant, and also less diverse, with only two extant genera and four species, which are limited to portions of southeastern Asia.
Alycaeus is a genus of land snails with a gill and an operculum, terrestrial gastropod mollusks in the family Cyclophoridae.
Tliltocatl aureoceps is a possible species of spider in the family Theraphosidae (tarantulas). The World Spider Catalog regards it as a nomen dubium. Only one female has been described; this was captured in the Florida Keys, but is likely to have been imported from Mexico.
Bledius annularis, or ringed borrow rove beetle, is a species of spiny-legged rove beetle in the family Staphylinidae. It is found in North America.
Protea madiensis, commonly known as the tall woodland sugarbush, is a flowering shrub which belongs to the genus Protea. It is native to the montane grasslands of Sub-Saharan Africa.
Halarachne americana, the Caribbean monk seal nasal mite, was a species of mite that inhabited the nasal cavity of the Caribbean monk seal.
Quercus sinuata var. sinuata, commonly called Durand oak, is a variety of Quercus sinuata, a species of oak tree that grows in parts of the southern United States and northeastern Mexico.
Limia sulphurophila, also known as sulphur limia, is a livebearing fish in the family Poeciliidae. It is endemic to the Dominican Republic in the island of Hispaniola.
