Juracrista is an extinct genus of squat lobster in the family Munididae. It was extant during the Jurassic Period, as the name suggests. [1] It contains the following species: [2]
The European robin, known simply as the robin or robin redbreast in Great Britain, is a small insectivorous passerine bird that belongs to the chat subfamily of the Old World flycatcher family. About 12.5–14.0 cm (4.9–5.5 in) in length, the male and female are similar in colouration, with an orange breast and face lined with grey, brown upper-parts and a whitish belly. It is found across Europe, east to Western Siberia and south to North Africa; it is sedentary in most of its range except the far north.
The flame robin is a small passerine bird native to Australia. It is a moderately common resident of the coolest parts of south-eastern Australia, including Tasmania. Like the other two red-breasted Petroica robins—the scarlet robin and the red-capped robin—it is often simply called the robin redbreast. Like many brightly coloured robins of the Petroicidae, it is sexually dimorphic. Measuring 12–14 cm (4.7–5.5 in) long, the flame robin has dark brown eyes and a small thin black bill. The male has a brilliant orange-red chest and throat, and a white patch on the forehead above the bill. Its upper parts are iron-grey with white bars, and its tail black with white tips. Female coloration is a muted grey-brown. Its song has been described as the most musical of its genus.
Melanophryniscus is a genus of toads in the family Bufonidae. They are found in northern half of Argentina, southern Bolivia, southern Brazil, Paraguay, and Uruguay. Common name South American redbelly toads has been coined for them.
Nomenclature codes or codes of nomenclature are the various rulebooks that govern biological taxonomic nomenclature, each in their own broad field of organisms. To an end-user who only deals with names of species, with some awareness that species are assignable to families, it may not be noticeable that there is more than one code, but beyond this basic level these are rather different in the way they work.
In botany, the correct name according to the International Code of Nomenclature for algae, fungi, and plants (ICN) is the one and only botanical name that is to be used for a particular taxon, when that taxon has a particular circumscription, position and rank. Determining whether a name is correct is a complex procedure. The name must be validly published, a process which is defined in no less than 16 Articles of the ICN. It must also be "legitimate", which imposes some further requirements. If there are two or more legitimate names for the same taxon, then the correct name is the one which has priority, i.e. it was published earliest, although names may be conserved if they have been very widely used. Validly published names other than the correct name are called synonyms. Since taxonomists may disagree as to the circumscription, position or rank of a taxon, there can be more than one correct name for a particular plant. These may also be called synonyms.
Pseudacris is a genus of frogs in the family Hylidae found in North America ranging from the Pacific coastline to the Atlantic.
Sinoconodon is an extinct genus of mammaliamorphs that appears in the fossil record of the Lufeng Formation of China in the Sinemurian stage of the Early Jurassic period, about 193 million years ago. While sharing many plesiomorphic traits with other non-mammaliaform cynodonts, it possessed a special, secondarily evolved jaw joint between the dentary and the squamosal bones, which in more derived taxa would replace the primitive tetrapod one between the articular and quadrate bones. The presence of a dentary-squamosal joint is a trait historically used to define mammals.
Palaeocursornis is a monotypic genus of pterosaurs. The only known species, P. corneti, was described in 1984 based on a single bone interpreted as the distal part of a left femur, found in Early Cretaceous (Berriasian rocks from a mine at Cornet near Oradea in northwestern Romania. It was initially assumed to be a flightless paleognathe bird, possibly a ratite, and later as a more primitive ornithuromorph or non-avialan theropod. However, re-evaluation of the specimen suggested that it was not a femur at all, but the upper arm bone of a pterodactyloid pterosaur similar to Azhdarcho.
The Tricholomataceae are a large family of mushrooms within the Agaricales. Originally a classic "wastebasket taxon", the family included any white-, yellow-, or pink-spored genera in the Agaricales not already classified as belonging to e.g. the Amanitaceae, Lepiotaceae, Hygrophoraceae, Pluteaceae, or Entolomataceae.
Lysorophus is a genus of Lysorophia, extinct Permian Lepospondyl tetrapods. Most of the specimens are found from North America and attributed to the first formally described species Lysorophus tricarinatus due to the lack of diagnostic characters, but several other species have been described. Lysorophus were small salamander-like amphibians. They lived in fresh water, aestivating in burrows during dry periods.
Protodiplatyidae is an extinct family of earwigs. It is one of three families in the suborder Archidermaptera, alongside Dermapteridae and Turanovia. Species are known from Jurassic and Early Cretaceous fossils and have unsegmented cerci and tarsi with four to five segments.
Terrabacteria is a taxon containing approximately two-thirds of prokaryote species, including those in the gram positive phyla as well as the phyla Cyanobacteria, Chloroflexi, and Deinococcus-Thermus.
Sequoioideae, popularly known as redwoods, is a subfamily of coniferous trees within the family Cupressaceae. It includes the largest and tallest trees in the world.
Angarioidea is a superfamily of small to medium sized sea snails, marine gastropod mollusks in the clade Vetigastropoda.
Areneidae is a family of sea snails, marine gastropod mollusks in the clade Vetigastropoda.
Helaletes is an extinct perissodactyl closely related to tapirs. Fossils have been found in North America.
Juracrista costaspinosa is an extinct species of squat lobster in the family Munididae. It was extant during the Jurassic Period.
Juracrista perculta is an extinct species of squat lobster in the family Munididae. It was extant during the Jurassic Period.
Butia arenicola is a very small species of Butia palm with an underground trunk; native to Paraguay and the state of Mato Grosso do Sul in Brazil. Boquierinho is recorded as a possible local vernacular name for it.
Iserosaurus is an extinct genus of sea turtle from the Late Cretaceous of Czech Republic.
