Dictyothyris is an extinct genus of brachiopods that lived from the Middle Jurassic to the Early Cretaceous throughout what is now Europe [1] [2] and North Africa. [1]
Like members of the Class Rhynchonellata, it is possible that members of this genus were blind. [3] They were also likely stationary suspension feeders, relying upon ocean currents to obtain food. [3] [4]
Species in the genus Dictyothyris include: [1] [3] [5] [6]
The asteroid belt is a torus-shaped region in the Solar System, centered on the Sun and roughly spanning the space between the orbits of the planets Jupiter and Mars. It contains a great many solid, irregularly shaped bodies called asteroids or minor planets. The identified objects are of many sizes, but much smaller than planets, and, on average, are about one million kilometers apart. This asteroid belt is also called the main asteroid belt or main belt to distinguish it from other asteroid populations in the Solar System.
Geoffrey Alan Landis is an American aerospace engineer and author, working for the National Aeronautics and Space Administration (NASA) on planetary exploration, interstellar propulsion, solar power and photovoltaics. He holds nine patents, primarily in the field of improvements to solar cells and photovoltaic devices and has given presentations and commentary on the possibilities for interstellar travel and construction of bases on the Moon, Mars, and Venus.
The Gruiformes are an order containing a considerable number of living and extinct bird families, with a widespread geographical diversity. Gruiform means "crane-like".
Sandra Hall Magnus is an American engineer and a former NASA astronaut. She returned to Earth with the crew of STS-119 Discovery on March 28, 2009, after having spent 134 days in orbit. She was assigned to the crew of STS-135, the final mission of the Space Shuttle. She is also a licensed amateur radio operator with the call sign KE5FYE. From 2012 until 2018 Magnus was the executive director of the American Institute of Aeronautics and Astronautics.
Halomonadaceae is a family of halophilic Pseudomonadota.
Deirochelys is a genus of freshwater turtle in the family Emydidae, the pond and marsh turtles. It contains one extant species, the chicken turtle, which is native to the southeastern United States. A second extinct member, Deirochelys carri, is known from a fossil found in Alachua County, Florida. The genus was first described by Louis Agassiz in 1857, and its name is derived from the Ancient Greek words for "neck" (deirḗ) and "tortoise" (khélūs), referring to the particularly long necks of these turtles.
Hugh Latimer Dryden was an American aeronautical scientist and civil servant. He served as NASA Deputy Administrator from August 19, 1958, until his death.
Gelechioidea is the superfamily of moths that contains the case-bearers, twirler moths, and relatives, also simply called curved-horn moths or gelechioid moths. It is a large and poorly understood '"micromoth" superfamily, constituting one of the basal lineages of the Ditrysia.
Oryzomys is a genus of semiaquatic rodents in the tribe Oryzomyini living in southern North America and far northern South America. It includes eight species, two of which—the marsh rice rat (O. palustris) of the United States and O. couesi of Mexico and Central America—are widespread; the six others have more restricted distributions. The species have had eventful taxonomic histories, and most species were at one time included in the marsh rice rat; additional species may be recognized in the future. The name Oryzomys was established in 1857 by Spencer Fullerton Baird for the marsh rice rat and was soon applied to over a hundred species of American rodents. Subsequently, the genus gradually became more narrowly defined until its current contents were established in 2006, when ten new genera were established for species previously placed in Oryzomys.
Carl Albert Oppel was a German paleontologist.
John Daniel "Danny" Olivas is an American engineer and a former NASA astronaut. Olivas has flown on two space shuttle missions, STS-117 and STS-128. He performed EVAs on both missions, totaling 34hrs 28min.
Northampton was a parliamentary constituency, which existed until 1974.
Gnathosaurus is a genus of ctenochasmatid pterosaur containing two species: G. subulatus, named in 1833 from the Solnhofen Limestone of Germany, and G. macrurus, known from the Purbeck Limestone of the UK. Its fossil remains dated back to the Late Jurassic period.
The Alethinophidia are an infraorder of snakes that includes all snakes other than blind snakes and thread snakes. Snakes have long been grouped into families within Alethinophidia based on their morphology, especially that of their teeth. More modern phylogenetic hypotheses using genetic data support the recognition of 19 extant families, although the taxonomy of alethinophidian snakes has long been debated, and ultimately the decision whether to assign a particular clade to a particular Linnaean rank is arbitrary.
Eric James Barron is an American academic administrator who was the 18th president of Pennsylvania State University from 2014 until 2022. He previously was the 14th president of Florida State University and director of the National Center for Atmospheric Research in Boulder, Colorado.
Jessica Ulrika Meir is an American NASA astronaut, marine biologist, and physiologist. She was previously an assistant professor of anesthesia at Harvard Medical School, Massachusetts General Hospital, Boston, following postdoctoral research in comparative physiology at the University of British Columbia. She has studied the diving physiology and behavior of emperor penguins in Antarctica, and the physiology of bar-headed geese, which are able to migrate over the Himalayas. In September 2002, Meir served as an aquanaut on the NASA Extreme Environment Mission Operations 4 crew. In 2013, she was selected by NASA to Astronaut Group 21. In 2016, Meir participated in ESA CAVES, a training course in which international astronauts train in a space-analogue cave environment. Meir launched on September 25, 2019, to the ISS onboard Soyuz MS-15, where she served as a flight Engineer during Expedition 61 and 62. On October 18, 2019, Meir and Christina Koch were the first women to participate in an all-female spacewalk.
Karen Kohanowich is a retired U.S. Naval officer and ocean research and technology program manager for the National Oceanic and Atmospheric Administration (NOAA)'s Office of Ocean Exploration and Research (OER). She was NOAA's Acting Director of the National Undersea Research Program (NURP) from 2006 to 2009, and served in various roles at OER, including Acting Deputy and Undersea Technology director, until retiring in 2018. In July 2006, she became an aquanaut on the NASA Extreme Environment Mission Operations 10 crew.
Colubroidea is a superfamily of snakes in the clade Colubroides that includes Colubridae, with some studies splitting Colubridae into multiple families that make up Colubroidea. Historically, Colubroidea also included other caenophidian snakes such as cobras and vipers, as these snakes form a clade. However these groups are now divided into several distinct, but related, families. Zaher et al. (2009) proposed to redefine Colubroidea for colubrids and related families, while designating Colubroides as the group containing vipers and cobras as well as colubroids. The ReptileDatabase considers Colubroidea to be composed of Colubridae and the members of its sister group, Elapoidea, and does not recognize the division of Colubridae into multiple families.
Sciapodinae is a subfamily of flies in the family Dolichopodidae. Members of the subfamily possess several ancestral characteristics of the family, such as branched vein M1+2 in the wings (though M2 is absent or reduced in Mesorhagini) and a pedunculate hypopygium. They also typically have a deeply excavated vertex, giving their heads the appearance of a dumbbell when viewed from the front.
Auguste Rollier was a Swiss physician best known for his research on heliotherapy.
