input question: Information:  - Alan Eugene Jackson (born October 17, 1958) is an American singer and songwriter. He is known for blending traditional honky tonk and mainstream country sounds and penning many of his own songs. Jackson has recorded 16 studio albums, three greatest hits albums, two Christmas albums, two gospel albums and several compilations.  - A Lot About Livin' (And a Little 'bout Love) is the third studio album by American country music artist Alan Jackson. It was released on October 6, 1992, and produced the singles "Chattahoochee", "She's Got the Rhythm (And I Got the Blues)", "Tonight I Climbed the Wall", "(Who Says) You Can't Have It All" and "Mercury Blues". "Chattahoochee" and "She's Got the Rhythm" were both Number One hits on the Hot Country Songs charts, while the other three songs all reached Top Five.  - Hot Country Songs is a chart published weekly by "Billboard" magazine in the United States.  - Country music is a genre of United States popular music that originated in the southern United States in the 1920s. It takes its roots from the southeastern genre of United States, such as folk music (especially Appalachian folk music), and blues music. Blues modes have been used extensively throughout its recorded history. Country music often consists of ballads and dance tunes with generally simple forms and harmonies accompanied by mostly string instruments such as banjos, electric and acoustic guitars, dobros and fiddles as well as harmonicas. According to Lindsey Starnes, the term "country music" gained popularity in the 1940s in preference to the earlier term "hillbilly music"; it came to encompass Western music, which evolved parallel to hillbilly music from similar roots, in the mid-20th century. The term "country music" is used today to describe many styles and subgenres. The origins of country music are the folk music of working-class Americans, who blended popular songs, Irish and Celtic fiddle tunes, traditional English ballads, and cowboy songs, and various musical traditions from European immigrant communities. In 2009 country music was the most listened to rush hour radio genre during the evening commute, and second most popular in the morning commute in the United States.  - `` Chattahoochee '' is a song co-written and recorded by American country music artist Alan Jackson . It was released in May 1993 as the third single from his album A Lot About Livin ' ( And a Little ' bout Love ) . The album is named for a line in the song itself .

input question: Information:  - Wiwaxia is a genus of soft-bodied animals that were covered in carbonaceous scales and spines. "Wiwaxia" fossils  mainly isolated scales, but sometimes complete, articulated fossils  are known from early Cambrian and middle Cambrian fossil deposits across the globe. The living animal would have measured up to 5 cm (2 inch) when fully grown, although a range of juvenile specimens are known, the smallest being long.  - A Lagerstätte (from "Lager" 'storage, lair' "Stätte" 'place'; plural "Lagerstätten") is a sedimentary deposit that exhibits extraordinary fossils with exceptional preservationsometimes including preserved soft tissues. These formations may have resulted from carcass burial in an anoxic environment with minimal bacteria, thus delaying decomposition. "Lagerstätten" span geological time from the Neoproterozoic era to the present. Worldwide, some of the best examples of near-perfect fossilization are the Cambrian Maotianshan shales and Burgess Shale, the Devonian Hunsrück Slates and Gogo Formation, the Carboniferous Mazon Creek, the Jurassic Solnhofen limestone, and the Cretaceous Santana and Yixian formations.  - Odontogriphus (literally "toothed riddle") is a genus of soft-bodied animals known from middle Cambrian Lagerstätte. Reaching as much as in length, "Odontogriphus" is a flat, oval bilaterian which apparently had a single muscular foot, and a "shell" on its back that was moderately rigid but of a material unsuited to fossilization.  - Nostoc is a genus of cyanobacteria found in various environments that forms colonies composed of filaments of moniliform cells in a gelatinous sheath.  - The Cambrian Period (or ) was the first geological period of the Paleozoic Era, of the Phanerozoic Eon. The Cambrian lasted 55.6 million years from the end of the preceding Ediacaran Period 541 million years ago (mya) to the beginning of the Ordovician Period mya. Its subdivisions, and its base, are somewhat in flux. The period was established (as Cambrian series) by Adam Sedgwick, who named it after Cambria, the Latinised form of "Cymru", the Welsh name for Wales, where Britain's Cambrian rocks are best exposed. The Cambrian is unique in its unusually high proportion of lagerstätte sedimentary deposits, sites of exceptional preservation where "soft" parts of organisms are preserved as well as their more resistant shells. As a result, our understanding of the Cambrian biology surpasses that of some later periods.  - Morania is a genus of cyanobacterium preserved as carbonaceous films in the Middle Cambrian Burgess Shale . it is present throughout the shale ; 2580 specimens of Morania are known from the Greater Phyllopod bed , where they comprise 4.90 % of the community . It is filamentous , forms sheets , and resembles the modern cyanobacterium Nostoc . It would have had a role in binding the sediment , and would have been a food source for such organisms as Odontogriphus and Wiwaxia .    Given the information, choose the subject and object entities that have the relation of 'parent taxon'.???
