Kootenichela
''Kootenichela deppi'' is an extinct arthropod described from the Middle Cambrian of the Kootenay National Park, Canada. It is originally considered to be a member of "great appendage arthropods", although subsequent studies questioned its affinity. ''Kootenichela'' appears to be the sister taxon of ''Worthenella'', from cladistic analysis. The species name ''deppi'' comes from the actor Johnny Depp, after his role as Edward Scissorhands in the film of the same name. David Legg, the discoverer of ''Kootenichela'', said: ''Kootenichela'' appears to be a primitive arthropod. It has an elongated body composed of at least 29 segments of similar shape and appearance. On the head, there are large eyes supported by stalks and an appendage resembling an antenna. The appendages bound to the trunk are poorly sclerotised. It was approximately long. Most prominent are the claw-like, spinose cephalic appendages, which seem to suggest affinities with Megacheira, the "great appendage" arthr ...

Megacheira
Megacheira ("great hands") is an extinct class of predatory arthropods that possessed a pair of great appendages, hence the class name as well as the common name "great appendage arthropods". Their taxonomic position is controversial, with studies either considering them stem-group euarthropods, or stem-group chelicerates. Most of them were found in marine environments throughout the world from the lower to middle Cambrian. Megacheirans were important components of several faunas, including the Burgess, Wheeler and Maotianshan Shales Lagerstatten. Homology of great appendages The homology between megacheiran great appendages and cephalic appendages of other arthropods had been discussed for decades. There is controversy over whether they are homologous to both dinocaridid (radiodonts and gilled lobopodians) frontal appendages, the frontalmost appendages of ''Isoxys'' and chelicerates' chelicerae. Based on neuroanatomical evidences, many studies support their homology to ch ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Edward Scissorhands
''Edward Scissorhands'' is a 1990 American fantasy romance film directed by Tim Burton. It was produced by Burton and Denise Di Novi, written by Caroline Thompson from a story by her and Burton, and starring Johnny Depp, Winona Ryder, Anthony Michael Hall, Dianne Wiest, Kathy Baker, Alan Arkin, and Vincent Price. It tells the story of an unfinished artificial humanoid who has scissor blades instead of hands that is taken in by a suburban family and falls in love with their teenage daughter. Burton conceived ''Edward Scissorhands'' from his childhood upbringing in suburban Burbank, California. During pre-production of ''Beetlejuice'', Caroline Thompson was hired to adapt Burton's story into a screenplay, and the film began development at 20th Century Fox after Warner Bros. declined. ''Edward Scissorhands'' was then fast tracked after Burton's critical and financial success with ''Batman''. The film also marks the fourth collaboration between Burton and film score composer Danny E ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

List Of Organisms Named After Famous People (born 1950–present)
In biological nomenclature, organisms often receive scientific names that honor a person. A taxon (e.g. species or genus; plural: taxa) named in honor of another entity is an eponymous taxon, and names specifically honoring a person or persons are known as patronyms. Scientific names are generally formally published in peer-reviewed journal articles or larger monographs along with descriptions of the named taxa and ways to distinguish them from other taxa. Following rules of Latin grammar, species or subspecies names derived from a man's name often end in ''-i'' or ''-ii'' if named for an individual, and ''-orum'' if named for a group of men or mixed-sex group, such as a family. Similarly, those named for a woman often end in ''-ae'', or ''-arum'' for two or more women. This list is part of the list of organisms named after famous people, and includes organisms named after famous individuals born on or after the 1st of January 1950. It also includes ensembles (including bands and c ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Kootenay National Park
Kootenay National Park is a national park of Canada located in southeastern British Columbia. The park consists of of the Canadian Rockies, including parts of the Kootenay and Park mountain ranges, the Kootenay River and the entirety of the Vermilion River. While the Vermilion River is completely contained within the park, the Kootenay River has its headwaters just outside the park boundary, flowing through the park into the Rocky Mountain Trench and eventually joining the Columbia River. The park ranges in elevation from at the southwestern park entrance to at Deltaform Mountain. Initially called "Kootenay Dominion Park", the park was created in 1920 as part of an agreement between the province of British Columbia and the Canadian federal government to build a highway in exchange for title to a strip of land, approximately on either side of the 94 km route, the Banff–Windermere Highway, to be used solely for park purposes. While the park is open all year, the major ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Chimera (paleontology)
In paleontology, a chimera is a fossil that was reconstructed with elements coming from more than a single species or genus of animal. In other words they are mistakes or sometimes hoaxes made by paleontologists, putting together parts that do not come from the same organism. A now classic example of chimera is ''Protoavis''.

Monotypic Arthropod Genera
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa. Examples Just as the term ''monotypic'' is used to describe a taxon including only one subdivision, the contained taxon can also be referred to as monotypic within the higher-level taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are: Plants * In the order Amborellales, there is only one family, Amborellaceae and there is only one genus, ''Amborella'', and in this genus there is only one species, namely ''Amborella trichopoda.'' ...

Cambrian Arthropods
The Cambrian Period ( ; sometimes symbolized Ꞓ) was the first geological period of the Paleozoic Era, and of the Phanerozoic Eon. The Cambrian lasted 53.4 million years from the end of the preceding Ediacaran Period 538.8 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 Latin name for 'Cymru' (Wales), where Britain's Cambrian rocks are best exposed. Sedgwick identified the layer as part of his task, along with Roderick Murchison, to subdivide the large "Transition Series", although the two geologists disagreed for a while on the appropriate categorization. The Cambrian is unique in its unusually high proportion of 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 biolo ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Prehistoric Arthropod Genera
Prehistory, also known as pre-literary history, is the period of human history between the use of the first stone tools by hominins 3.3 million years ago and the beginning of recorded history with the invention of writing systems. The use of symbols, marks, and images appears very early among humans, but the earliest known writing systems appeared 5000 years ago. It took thousands of years for writing systems to be widely adopted, with writing spreading to almost all cultures by the 19th century. The end of prehistory therefore came at very different times in different places, and the term is less often used in discussing societies where prehistory ended relatively recently. In the early Bronze Age, Sumer in Mesopotamia, the Indus Valley Civilisation, and ancient Egypt were the first civilizations to develop their own scripts and to keep historical records, with their neighbors following. Most other civilizations reached the end of prehistory during the following Iron Age. T ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Cladistic
Cladistics (; ) is an approach to biological classification in which organisms are categorized in groups (" clades") based on hypotheses of most recent common ancestry. The evidence for hypothesized relationships is typically shared derived characteristics ( synapomorphies'')'' that are not present in more distant groups and ancestors. However, from an empirical perspective, common ancestors are inferences based on a cladistic hypothesis of relationships of taxa whose character states can be observed. Theoretically, a last common ancestor and all its descendants constitute a (minimal) clade. Importantly, all descendants stay in their overarching ancestral clade. For example, if the terms ''worms'' or ''fishes'' were used within a ''strict'' cladistic framework, these terms would include humans. Many of these terms are normally used paraphyletically, outside of cladistics, e.g. as a 'grade', which are fruitless to precisely delineate, especially when including extinct species. R ...
