Context: The Sebacinales are an order of fungi in the class Agaricomycetes. Taxa have a widespread distribution and are mostly terrestrial, many forming mycorrhizas with a wide variety of plants, including orchids. The order is monotypic, containing a single family, the Sebacinaceae. There are 8 genera and 29 species in the family., Jaapiales is an order of fungi in the class Agaricomycetes (subclass Agaricomycetidae). It was first described in 2010 to contain Jaapia, a genus of resupinate species that were until then classified in the order Boletales. Molecular phylogenetics analysis showed it to be a sister group (one of two clades resulting from the splitting of a single lineage) to the rest of the Agaricomycetidae., Phlyctibasidium is a fungal genus of uncertain taxonomic placement in the Agaricomycetes . This is a monotypic genus , containing the single corticioid species Phlyctibasidium polyporoideum ., The Dacrymycetes are a class consisting of only one family of jelly fungi, which has imperforate parenthesomes and basidia that are usually branched. There are 9 genera and 101 species in the Dacrymycetaceae family., The Agaricomycetes are a class of fungi in the division Basidiomycota. The taxon is roughly identical to that defined for the Homobasidiomycetes (alternatively called holobasidiomycetes) by Hibbett & Thorn, with the inclusion of Auriculariales and Sebacinales. It includes not only mushroom-forming fungi, but also most species placed in the deprecated taxa Gasteromycetes and Homobasidiomycetes. Within the subdivision Agaricomycotina, which already excludes the smut and rust fungi, the Agaricomycetes can be further defined by the exclusion of the classes Tremellomycetes and Dacrymycetes, which are generally considered to be jelly fungi. However, a few former "jelly fungi", such as "Auricularia", are classified in the Agaricomycetes. According to a 2008 estimate, Agaricomycetes include 17 orders, 100 families, 1147 genera, and about 21000 species. Modern molecular phylogenetic analyses have been since used to help define several new orders in the Agaricomycetes: Amylocorticiales, Jaapiales, Stereopsidales, and Lepidostromatales., The Auriculariales are an order of fungi in the class Agaricomycetes. Species within the order were formerly referred to the "heterobasidiomycetes" or "jelly fungi", since many have gelatinous basidiocarps (fruit bodies) that produce spores on septate basidia. Around 200 species are known worldwide, placed in six or more families, though the status of these families is currently uncertain. All species in the Auriculariales are believed to be saprotrophic, most growing on dead wood. Fruit bodies of several "Auricularia" species are cultivated for food on a commercial scale, especially in China., The subdivision Agaricomycotina, also known as the hymenomycetes, is one of three taxa of the fungal division Basidiomycota (fungi bearing spores on basidia). The Agaricomycotina contain some 20,000 species, and about 98% of these are in the class Agaricomycetes, which comprises most of the fungi known as mushrooms, including the bracket fungi and puffballs. Species in the Agaricomycotina that are not Agaricomycetes include the jelly fungi, certain "yeasts", ear fungi, and others; these are gathered together as the classes Tremellomycetes and Dacrymycetes., Auricularia is a genus of jelly fungi in the family Auriculariaceae. Preliminary phylogenetic studies suggest the Exidiaceae is closely related to Auriculariaceae, the two share many morphological traits. Fruitbody either resupinate or pileate and then either ear-to shell-shaped or forming narrow, imbricate brackets, flabby elastic or tough gelatinous; hymenial surface smooth, wrinkled or veined, often purplish. Basidia cylindrical, with 1-3 transeverse septa. Spores narrowly ellipsoid to allantoid, hyaline, smooth. Most "Auricularia" species are edible and are grown commercially. "Auricularia" species are widely distributed in the Western Ghats, Kerala and recently, "Auricularia auricula-judae", "A. polytricha" and "A. mesenterica" have been reported., The Tremellomycetes are a class of dimorphic fungi. Some species have a gelatinous fruiting body or a sacculate parenthesome. There are 3 orders, 11 families, 50 genera, and 377 species in the Tremellomycetes., Basidiomycota is one of two large divisions that, together with the Ascomycota, constitute the subkingdom Dikarya (often referred to as the "higher fungi") within the kingdom Fungi., Subject: phlyctibasidium, Relation: parent_taxon, Options: (A) agaricomycetes (B) agaricomycetidae (C) agaricomycotina (D) auricularia (E) auriculariales (F) basidiomycota (G) dacrymycetes (H) dikarya (I) fungi (J) kerala (K) sebacinales (L) tremellomycetes

Context: Chalk is a soft, white, porous, sedimentary carbonate rock, a form of limestone composed of the mineral calcite. Calcite is an ionic salt called calcium carbonate or CaCO. It forms under reasonably deep marine conditions from the gradual accumulation of minute calcite shells (coccoliths) shed from micro-organisms called coccolithophores. Flint (a type of chert unique to chalk) is very common as bands parallel to the bedding or as nodules embedded in chalk. It is probably derived from sponge spicules or other siliceous organisms as water is expelled upwards during compaction. Flint is often deposited around larger fossils such as Echinoidea which may be silicified (i.e. replaced molecule by molecule by flint)., The Indo-European languages are a language family of several hundred related languages and dialects. There are about 445 living Indo-European languages, according to the estimate by "Ethnologue", with over two-thirds (313) of them belonging to the Indo-Iranian branch. The most widely spoken Indo-European languages by native speakers are Spanish, English, Hindustani (Hindi and Urdu), Portuguese, Bengali, Russian, Persian and Punjabi, each with over 100 million speakers. Today, 46% of the human population speaks an Indo-European language natively, by far the highest of any language family., The Paleogene (or ; also spelled Palaeogene or Palæogene; informally Lower Tertiary) is a geologic period and system that spans 43 million years from the end of the Cretaceous Period million years ago (Mya) to the beginning of the Neogene Period Mya. It is the beginning of the Cenozoic Era of the present Phanerozoic Eon. The Paleogene is most notable for being the time during which mammals diversified from relatively small, simple forms into a large group of diverse animals in the wake of the CretaceousPaleogene extinction event that ended the preceding Cretaceous Period. , The Cretaceous is a geologic period and system that spans 79 million years from the end of the Jurassic Period million years ago (Mya) to the beginning of the Paleogene Period Mya. It is the last period of the Mesozoic Era. The Cretaceous Period is usually abbreviated K, for its German translation "Kreide" (chalk)., Latin (Latin: ) is a classical language belonging to the Italic branch of the Indo-European languages. The Latin alphabet is derived from the Etruscan and Greek alphabets., Bison are large, even-toed ungulates in the genus "Bison" within the subfamily Bovinae., Silvisaurus , from the Latin silva `` woodland '' and Greek sauros `` lizard '' , is a nodosaurid ankylosaur from the middle Cretaceous of Kansas ., Kansas is a U.S. state located in the Midwestern United States. Its capital is Topeka and its largest city is Wichita. Kansas is named after the Kansa Native American tribe, which inhabited the area. The tribe's name (natively "") is often said to mean "people of the wind" or "people of the south wind", although this was probably not the term's original meaning. For thousands of years, what is now Kansas was home to numerous and diverse Native American tribes. Tribes in the eastern part of the state generally lived in villages along the river valleys. Tribes in the western part of the state were semi-nomadic and hunted large herds of bison., Subject: silvisaurus, Relation: taxon_rank, Options: (A) branch (B) family (C) form (D) genus (E) group (F) tribe

Context: Aetosaurinae is one of the two subfamilies of aetosaurs, the other being Desmatosuchinae. It is a stem-based taxon defined as all aetosaurs more closely related to "Aetosaurus" than to the last common ancestor of "Aetosaurus" and "Desmatosuchus". The only synapomorphy that diagnoses the clade Aetosaurinae is the medial offset of the dorsal eminences of the paramedian osteoderms. A phylogenetic study in 2012 found Aetosaurinae to be paraphyletic, with "Aetosaurus" being the basal-most stagonolepidid and aetosaurines like "Calyptosuchus", "Neoaetosauroides", and the newly described "Aetobarbakinoides" being successively more derived taxa leading up to a clade containing Desmatosuchinae and Typothoracisinae. Under this phylogeny, most traditional aetosaurines are more closely related to "Desmatosuchus" than they are to "Aetosaurus", and the clade Aetosaurinae can only include "Aetosaurus"., Typothoracisinae is a clade of aetosaurs within the subfamily Aetosaurinae. It is a stem-based taxon defined as all aetosaurs closer to "Typothorax" than to "Stagonolepis" or "Desmatosuchus". As with many aetosaur taxa, most of the synapomorphies that diagnose the clade are found in the osteoderms. These include a strongly acute angle of flexion between the dorsal and lateral flanges of the dorsal and lateral plates and triangular-shaped pelvic and anterior caudal dorsal lateral plates possessing semicircular borders and hook-like eminences., Desmatosuchinae is one of the two subfamilies of aetosaurs , the other being Aetosaurinae . It is a stem - based taxon defined as all aetosaurs more closely related to Desmatosuchus than the last common ancestor of Desmatosuchus and Stagonolepis . All synapomorphies that diagnose the clade can be found in the osteoderms . These include tongue - and - groove articulations for lateral plates present in dorsal presacral paramedian plates and large spikes on the lateral cervical , dorsal , and caudal plates ., Calyptosuchus (meaning "covered crocodile") is an extinct genus of crurotarsan from the Late Triassic of North America. As an aetosaur, it was heavily armored and had a pig-like snout used to uproot plants. The genus might be a junior synonym of "Stagonolepis"., Aetosaurs ("aetosaur" ; order name "Aetosauria" ; from Greek, (aetos, "eagle") and (sauros, "lizard")) are an extinct order of heavily armoured, medium- to large-sized Late Triassic herbivorous archosaurs. They have small heads, upturned snouts, erect limbs, and a body covered by plate-like scutes. All aetosaurs belong to the family Stagonolepididae. Two distinct subdivisions of aetosaurs are currently recognized, Desmatosuchinae and Aetosaurinae, based primarily on differences in the morphology of the bony scutes of the two groups. Over 20 genera of aetosaurs have been described, and recently there has been controversy regarding the description of some of these genera., Stagonolepis is an extinct genus of stagonolepidid aetosaur known from the Late Triassic (Carnian stage) of Europe., Neoaetosauroides is an extinct genus of primitive aetosaur. Its type and only species is "N. engaeus". Fossils have been found from the Los Colorados Formation outcropping along the Sierra Morada River in La Rioja, Argentina, and date back to the Norian age of the Late Triassic. It was the first aetosaur known from the formation, with remains being discovered in the 1960s., Desmatosuchus (from Greek  "desmos" 'link' +  "soûkhos" 'crocodile') is an extinct genus of archosaur belonging to the Order Aetosauria. It lived during the Late Triassic., Aetosaurus is an extinct genus of archosaur reptile belonging to the order Aetosauria. It is generally considered to be the most primitive aetosaur. Three species are currently recognized: "A. ferratus", the type species from Germany and Italy; "A. crassicauda" from Germany; and "A. arcuatus" from eastern North America. Additional specimens referred to "Aetosaurus" have been found from South Africa, the Chinle Group of the southwestern United States, and the Fleming Fjord Formation of Greenland. Specimens of "Aetosaurus" occur in Norian-age strata., Archosaurs are a group of diapsid amniotes whose living representatives consist of birds and crocodilians. This group also includes all extinct non-avian dinosaurs, extinct crocodilian relatives, and pterosaurs. Archosauria, the archosaur clade, is a crown group that includes the most recent common ancestor of living birds and crocodilians. It includes two main clades: Pseudosuchia, which includes crocodilians and their extinct relatives, and Ornithosuchia, which includes birds and their extinct relatives (such as non-avian dinosaurs and pterosaurs)., Subject: desmatosuchinae, Relation: parent_taxon, Options: (A) aetosaur (B) aetosaurinae (C) archosaur (D) argentina (E) crocodile (F) desmatosuchinae (G) desmos (H) diapsid (I) la (J) lizard (K) pig (L) reptile (M) stagonolepididae
