Information: - The Triassic is a geologic period and system which spans 50.9 million years from the end of the Permian Period million years ago (Mya), to the beginning of the Jurassic Period Mya. The Triassic is the first period of the Mesozoic Era. Both the start and end of the period are marked by major extinction events. The Triassic was named in 1834 by Friedrich von Alberti, after the three distinct rock layers ("tri" meaning "three") that are found throughout Germany and northwestern Europered beds, capped by marine limestone, followed by a series of terrestrial mud- and sandstonescalled the "Trias". - In the geologic timescale, the Sinemurian is an age or stage in the Early or Lower Jurassic epoch or series. It spans the time between 199.3 2 Ma and 190.8 1.5 Ma (million years ago). The Sinemurian is preceded by the Hettangian and is followed by the Pliensbachian. - The squamosal is a bone of the head of higher vertebrates. It is the principal component of the cheek region in the skull, lying below the temporal series and otic notch and bounded anteriorly by the postorbital. Posteriorly, the squamosal articulates with the posterior elements of the palatal complex, namely the quadrate and pterygoid. The squamosal is bordered anteroventrally by the jugal and ventrally by the quadratojugal. - The Early Jurassic epoch (in chronostratigraphy corresponding to the Lower Jurassic series) is the earliest of three epochs of the Jurassic period. The Early Jurassic starts immediately after the Triassic-Jurassic extinction event, 201.3 Ma(million years ago), and ends at the start of the Middle Jurassic 174.1Ma. - Sinoconodon rigneyi is an ancient mammaliamorph or early mammal ( depending on systematic approach ) that appears in the fossil record of China in the Sinemurian stage of the Early Jurassic period , about 193 million years ago . While in many traits very similar to reptiles , it possessed a special , secondarily evolved jaw joint between the dentary and the squamosal bones , which had replaced the primitive reptilian one between the articular and quadrate bones , a trait commonly used to define mammals . Although the animal is closely related to Morganucodon , it is regarded as the most basal of the mammaliaforms . It differed substantially from the more mammalian Morganucodon in its dental and growth habits . Like the reptiles , it was polyphyodont , replacing many of its teeth throughout its lifetime , and it seems to have grown slowly but continuously until its death . Sinoconodon is thus less mammalian than early mammaliaforms like docodonts and morganucodonts . Even the smallest known individuals had already begun the teething cycle of the front teeth , and combined with a poorly ossified jaw , it very probably did not suckle . The combination of reptilian and mammalian features makes it straddle the divide between the two classes anatomically and likely ecologically . There are simply no animals like it alive today . - Juga is a genus of freshwater snails with a gill and an operculum, aquatic gastropod mollusks in the family Semisulcospiridae. - Chronostratigraphy is the branch of stratigraphy that studies the age of rock strata in relation to time. - The Pliensbachian is an age of the geologic timescale or stage in the stratigraphic column. It is part of the Early or Lower Jurassic epoch or series and spans the time between 190.8 1.5 Ma and 182.7 1.5 Ma (million years ago). The Pliensbachian is preceded by the Sinemurian and followed by the Toarcian. 'sinoconodon' is related to which object entity through the relation of 'taxon rank'? Choices: - branch - genus - series

Information: - Ian Ernest Gilmore "Gil" Evans (born Green; May 13, 1912 March 20, 1988) was a Canadian jazz pianist, arranger, composer and bandleader. He is widely recognized as one of the greatest orchestrators in jazz, playing an important role in the development of cool jazz, modal jazz, free jazz and jazz fusion.

The term is most commonly, though not exclusively, used with a group that plays popular music as a small combo or a big band, such as one which plays jazz, blues, rhythm and blues or rock and roll music. Most bandleaders are also performers with their own band, either as singers or as instrumentalists, playing an instrument such as electric guitar, piano, or other instruments. - Cornell Luther Dupree (December 19, 1942 May 8, 2011) was an American jazz and R&B guitarist. He worked at various times with Bill Withers, Donny Hathaway, King Curtis and Steve Gadd, appeared on David Letterman, and wrote a book on soul and blues guitar: "Rhythm and Blues Guitar." He reportedly recorded on 2,500 sessions. - Stephen Kendall "Steve" Gadd (born April 9, 1945) is an American drummer, percussionist and session musician. Gadd is one of the most well-known and highly regarded session and studio drummers in the industry, recognized by his induction into the "Modern Drummer" Hall of Fame in 1984. Gadd's groove on Paul Simon's "50 Ways to Leave Your Lover", and drum solo on Steely Dan's "Aja", are both examples of his seminal sound and signature style. He has worked with popular musicians from a wide range of genres including notably Simon & Garfunkel, Steely Dan, James Taylor, Eric Clapton, Joe Cocker, Grover Washington Jr., Chick Corea, Lee Ritenour and Al Di Meola. - A guitarist (or a guitar player) is a person who plays the guitar. Guitarists may play a variety of guitar family instruments such as classical guitars, acoustic guitars, electric guitars, and bass guitars. Some guitarists accompany themselves on the guitar by singing or playing the harmonica. - Trevor Koehler ( 1935 - 1975 ) was an American saxophonist . He recorded with Gil Evans , The Insect Trust , Cornell Dupree , Lou Reed , Octopus . Allan Houser wrote a jazz piece called '' Running Wild With Trevor Koehler '' that he recorded with his sextet . Father of Glade Koehler and Seth Koehler . Trevor Koehler committed suicide in 1975 . - Curtis Ousley (February 7, 1934 August 13, 1971), who performed under the stage name King Curtis, was an American saxophone virtuoso known for rhythm and blues, rock and roll, soul, blues, funk and soul jazz. Variously a bandleader, band member, and session musician, he was also a musical director and record producer.
