Sinoburius
''Sinoburius'' is an extinct genus of xandarellid artiopodan known from the Cambrian aged Chengjiang Biota The Maotianshan Shales are a series of Early Cambrian deposits in the Chiungchussu Formation, famous for their '' Konservat Lagerstätten'', deposits known for the exceptional preservation of fossilized organisms or traces. The Maotianshan Shales ... of China. It is only known from the type species ''S. lunaris'', which was described in 1991. It is a rare fossil within the Chengjiang assemblage. Like other Xandarellids, ''Sinoburius'' has an unmineralised exoskeleton. Adult individuals are around 7-8 millimetres in length, with stalked eyes present on the ventral side. Unusually among artiopods, the antennae are strongly reduced in size. References Artiopoda Fossil taxa described in 1991 {{paleo-arthropod-stub ...

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] |

"Cinderella",; french: link=no, Cendrillon; german: link=no, Aschenputtel) or "The Little Glass Slipper", is a folk tale with thousands of variants throughout the world.Dundes, Alan. Cinderella, a Casebook. Madison, Wis: University of Wisconsin Press, 1988. The protagonist is a young woman living in forsaken circumstances that are suddenly changed to remarkable fortune, with her ascension to the throne via marriage. The story of Rhodopis, recounted by the Greek geographer Strabo sometime between around 7 BC and AD 23, about a Greek slave girl who marries the king of Egypt, is usually considered to be the earliest known variant of the Cinderella story.Roger Lancelyn Green: ''Tales of Ancient Egypt'', Penguin UK, 2011, , chapter "The Land of Egypt" The first literary European version of the story was published in Italy by Giambattista Basile in his ''Pentamerone'' in 1634; the version that is now most widely known in the English-speaking world was published in French by Charles ...

Cambrian Explosion
The Cambrian explosion, Cambrian radiation, Cambrian diversification, or the Biological Big Bang refers to an interval of time approximately in the Cambrian Period when practically all major animal phyla started appearing in the fossil record. It lasted for about 13 – 25 million years and resulted in the divergence of most modern metazoan phyla. The event was accompanied by major diversification in other groups of organisms as well. Before early Cambrian diversification, most organisms were relatively simple, composed of individual cells, or small multicellular organisms, occasionally organized into colonies. As the rate of diversification subsequently accelerated, the variety of life became much more complex, and began to resemble that of today. Almost all present-day animal phyla appeared during this period, including the earliest chordates. A 2019 paper suggests that the timing should be expanded back to include the late Ediacaran, rather than just the n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arthropod
Arthropods (, (gen. ποδός)) are invertebrate animals with an exoskeleton, a Segmentation (biology), segmented body, and paired jointed appendages. Arthropods form the phylum Arthropoda. They are distinguished by their jointed limbs and Arthropod cuticle, cuticle made of chitin, often Mineralization (biology), mineralised with calcium carbonate. The arthropod body plan consists of segments, each with a pair of appendages. Arthropods are bilaterally symmetrical and their body possesses an exoskeleton, external skeleton. In order to keep growing, they must go through stages of moulting, a process by which they shed their exoskeleton to reveal a new one. Some species have wings. They are an extremely diverse group, with up to 10 million species. The haemocoel, an arthropod's internal cavity, through which its haemolymph – analogue of blood – circulates, accommodates its interior Organ (anatomy), organs; it has an open circulatory system. Like their exteriors, the internal or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Xandarella
''Xandarella'' is an extinct genus of xandarellid artiopodan known from the Cambrian of China and Morocco, the type species ''Xandarella spectaculum'' was described in 1991 from the Cambrian Stage 3 aged Chengjiang Biota in China. An additional species ''Xandarella mauretanica'' was described from the Cambrian Stage 5 Tatelt Formation in Morocco in 2017, which preserved only the ventral Standard anatomical terms of location are used to unambiguously describe the anatomy of animals, including humans.

Like other Xandarellids, the exoskeleton is unmineralised. The cephalon has pronounced eye slits, presumably derived from ancestral ventral stalked eyes.

Phytophilaspis
''Phytophilaspis'' is a phosphatized genus of trilobite-like arthropod with eyes, found in association with algal remains. It dwelt in well-lit, shallow waters. Description ''Phytophilaspis'' has several features in common with trilobites, including: tripartite division of the dorsal shield; presence of prominent pygidium; large eyes, situated on the pleural area of the cephalon; facial sutures, and shape of the hypostome. However, it differs from trilobites in many ways, including a reduced thorax, thoracic pleura fused to each other and to the cephalon and pygidium, facial sutures not crossing the eyes, and weak original mineralization of the cuticle. Because of these differences, ''Phytophilaspis'' was originally assigned to the Artiopodan subclass Concilliterga, in an undetermined order and family. It was later considered by Bergström and Hou as a xandarellid, along with ''Cindarella'', ''Xandarella'' and ''Sinoburius''. A position that was supported in subsequent studies. ...

Artiopoda
The Artiopoda is a grouping of extinct arthropods that includes trilobites and their close relatives. It was erected by Hou and Bergström in 1997 to encompass a wide diversity of arthropods that would traditionally have been assigned to the Trilobitomorpha. Hou and Bergström used the name Lamellipedia as a superclass to replace Trilobitomorpha that was originally erected at the subphylum level, which they considered inappropriate. Trilobites, in part due to their mineralising exoskeletons, are by far the most diverse and long lived members of the clade, with most records of other members, which lack mineralised exoskeletons, being from Cambrian deposits. Description According to Stein and Selden (2012) artiopods are recognised by the possession of filiform antennulae, limbs with bilobate exopods, with the proximal lobe being elongate and bearing a lamella, while the distal lobe is paddle-shaped and setiforous (bearing hair-or bristle like structures). The limb endopod has se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
