Information:  - Sclerorhynchidae is an extinct family of cartilaginous fish from the Cretaceous and Paleogene belonging to the primitive Batoidea suborder Sclerorhynchiformes.  - A genus ( genera) is a taxonomic rank used in the biological classification of living and fossil organisms in biology. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus.  - Libanopristis is an extinct genus of sawfish belonging to the family Sclerorhynchidae .  - Binomial nomenclature (also called binominal nomenclature or binary nomenclature) is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (which may be shortened to just "binomial"), a binomen or a scientific name; more informally it is also called a Latin name. The first part of the name identifies the genus to which the species belongs; the second part identifies the species within the genus. For example, humans belong to the genus "Homo" and within this genus to the species "Homo sapiens". The "formal" introduction of this system of naming species is credited to Carl Linnaeus, effectively beginning with his work "Species Plantarum" in 1753. But Gaspard Bauhin, in as early as 1623, had introduced in his book "Pinax theatri botanici" (English, "Illustrated exposition of plants") many names of genera that were later adopted by Linnaeus.  - 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.   - In biology, an organism is any contiguous living system, such as an animal, plant, fungus, archaeon, or bacterium. All known types of organisms are capable of some degree of response to stimuli, reproduction, growth and development and homeostasis. An organism consists of one or more cells; when it has one cell it is known as a unicellular organism; and when it has more than one it is known as a multicellular organism. Most unicellular organisms are of microscopic scale and are thus loosely described as microorganisms. Humans are multicellular organisms composed of many trillions of cells grouped into specialized tissues and organs.  - In cryptography, SHARK is a block cipher identified as one of the predecessors of Rijndael (the Advanced Encryption Standard).  - In the context of human society, a family (from ) is a group of people affiliated either by consanguinity (by recognized birth), affinity (by marriage or any other relationship like siblings families etc..), or co-residence (as implied by the etymology of the English word "family")  or some combination of these. Members of the immediate family include spouses, parents, brothers, sisters, sons, and/or daughters. Members of the extended family may include grandparents, aunts, uncles, cousins, nephews, nieces, and/or siblings-in-law. Sometimes these are also considered members of the immediate family, depending on an individual's specific relationship with them.  - 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).  - Sawfishes, also known as carpenter sharks, are a family of rays characterized by a long, narrow, flattened rostrum, or nose extension, lined with sharp transverse teeth, arranged so as to resemble a saw. Several species of sawfishes can grow to about . The family as a whole is largely unknown and little studied. The Pristidae are the only living family within the order Pristiformes, whose name comes from the .    'libanopristis' is related to which object entity through the relation of 'parent taxon'?

Ques: Information:  - Procol Harum are an English rock band formed in 1967. They contributed to the development of symphonic rock, and by extension, progressive rock. Their best-known recording is their 1967 hit single "A Whiter Shade of Pale", which is considered a classic of popular music and is one of the few singles to have sold over 10 million copies. Although noted for its baroque and classical influence, Procol Harum's music also embraces the blues, R&B, and soul.  - A power trio is a rock and roll band format having a lineup of guitar, bass and drums, leaving out the second guitar or keyboard that are used in other rock music quartets and quintets to fill out the sound with chords. While one or more band members typically sing, power trios emphasize instrumental performance and overall impact over vocals and lyrics. History. The rise of the power trio in the 1960s was made possible in part by developments in amplifier technology that greatly enhanced the volume of the electric guitar and bass. Particularly, the popularization of the electric bass guitar defined the bottom end and filled in the gaps. Since the amplified bass could also now be louder, the rest of the band could also play at higher volumes, without fear of being unable to hear the bass. This allowed a three-person band to have the same sonic impact as a large band but left far more room for improvisation and creativity, unencumbered by the need for detailed arrangements. As with the organ trio, a 1960s-era soul jazz group centered on the amplified Hammond organ, a three-piece group could fill a large bar or club with a big sound for a much lower price than a large rock and roll band. A power trio, at least in its blues rock incarnation, is also generally held to have developed out of Chicago-style blues bands such as Muddy Waters' trio.  - Robin Leonard Trower (born 9 March 1945) is an English rock guitarist and vocalist who achieved success with Procol Harum during the 1960s, and then again as the bandleader of his own power trio.  - 20th Century Blues is the fifteenth studio album by Robin Trower .
