Mazoscolopendra
''Mazoscolopendra'' is an extinct genus of scolopendromorph centipedes, and the oldest known member of that order. It existed during the Carboniferous in what is now Illinois (found in Mazon Creek fossil beds). With length up to , this centipede had 21 pedal segments. Although family it belongs to is uncertain, in the original description it is suggested that is close to Cryptopidae than to Scolopendridae Scolopendridae (or, in older documents, Scolopendridæ), from Ancient Greek σκόλοψ (''skólops''), meaning "thorn", and ἔντερον (''énteron''), meaning "earthworm", is a family of large centipedes (class Chilopoda).

Chilopoda
Centipedes (from Neo-Latin , "hundred", and Latin language, Latin , "foot") are predatory arthropods belonging to the class Chilopoda (Ancient Greek , ''kheilos'', "lip", and Neo-Latin suffix , "foot", describing the forcipules) of the subphylum Myriapoda, an arthropod group which includes millipedes and other multi-legged animals. Centipedes are elongated segmented (Metamerism (biology), metameric) animals with one pair of legs per body segment. All centipedes are venomous and can inflict painful centipede bite, stings, injecting their venom through Pincer (biology), pincer-like appendages known as forcipules or toxicognaths, which are actually modified legs instead of fangs. Despite the name, no species of centipede has exactly 100 legs; the number of pairs of legs is an odd number that ranges from 15 pairs to 191 pairs. Centipedes are predominantly generalist (biology), generalist carnivore, carnivorous, hunting for a variety of prey items that can be overpowered. They have ...

Mazon Creek Fossil Beds
The Mazon Creek fossil beds are a conservation ' found near Morris, in Grundy County, Illinois. The fossils are preserved in ironstone concretions, formed approximately in the mid- Pennsylvanian epoch of the Carboniferous period. These concretions frequently preserve both hard and soft tissues of animal and plant materials, as well as many soft-bodied organisms that do not normally fossilize. The quality, quantity and diversity of fossils in the area, known since the mid-nineteenth century, make the Mazon Creek ' important to paleontologists attempting to reconstruct the paleoecology of the sites. The locality was declared a National Historic Landmark in 1997.. Geology The Mazon Creek fossils are found in the Upper Carboniferous Francis Creek Shale. The type locality is the Mazon River (or Mazon Creek), a tributary of the Illinois River near Morris, Grundy County, Illinois. The 25 to 30 meters of shale were formed approximately , during the Pennsylvanian period. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Animalia
Animals are multicellular, eukaryotic organisms in the Biology, biological Kingdom (biology), kingdom Animalia (). With few exceptions, animals heterotroph, consume organic material, Cellular respiration#Aerobic respiration, breathe oxygen, have myocytes and are motility, able to move, can reproduce sexually, and grow from a hollow sphere of Cell (biology), cells, the blastula, during embryonic development. Animals form a clade, meaning that they arose from a single common ancestor. Over 1.5 million extant taxon, living animal species have been species description, described, of which around 1.05 million are insects, over 85,000 are molluscs, and around 65,000 are vertebrates. It has been estimated there are as many as 7.77 million animal species on Earth. Animal body lengths range from to . They have complex ecologies and biological interaction, interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as ...

Arthropoda
Arthropods ( ) are invertebrates in the phylum Arthropoda. They possess an exoskeleton with a cuticle made of chitin, often mineralised with calcium carbonate, a body with differentiated ( metameric) segments, and paired jointed appendages. 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. They form an extremely diverse group of up to ten million species. Haemolymph is the analogue of blood for most arthropods. An arthropod has an open circulatory system, with a body cavity called a haemocoel through which haemolymph circulates to the interior organs. Like their exteriors, the internal organs of arthropods are generally built of repeated segments. They have ladder-like nervous systems, with paired ventral nerve cords running through all segments and forming paired ganglia in each segment. Their heads are formed by fusion of varying numbers of segments, and their brains are formed by fu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scolopendromorpha
Scolopendromorpha is an order of centipedes also known as tropical centipedes or bark centipedes. This order includes about 700 species in five families. These centipedes are found nearly worldwide, with tropical and subtropical regions providing the richest diversity in species. This order includes the only known amphibious centipedes, ''Scolopendra cataracta'', ''Scolopendra paradoxa'', and ''Scolopendra alcyona''.> Description The centipedes in this order are wikt:epimorphic, epimorphic, hatching with a full complement of segments. They usually possess 21 or 23 trunk segments with the same number of paired legs. The number of leg pairs is fixed at 21 for most species in this order and fixed at 23 for the remaining species, except for two species with intraspecific variation: ''Scolopendropsis bahiensis'', which has 21 or 23 leg pairs, and ''Scolopendropsis duplicata, S. duplicata'', which has 39 or 43 leg pairs. Species in this order have flattened bodies ranging from 9 mm to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carboniferous
The Carboniferous ( ) is a Geologic time scale, geologic period and System (stratigraphy), system of the Paleozoic era (geology), era that spans 60 million years, from the end of the Devonian Period Ma (million years ago) to the beginning of the Permian Period, Ma. It is the fifth and penultimate period of the Paleozoic era and the fifth period of the Phanerozoic eon (geology), eon. In North America, the Carboniferous is often treated as two separate geological periods, the earlier Mississippian (geology), Mississippian and the later Pennsylvanian (geology), Pennsylvanian. The name ''Carboniferous'' means "coal-bearing", from the Latin ("coal") and ("bear, carry"), and refers to the many coal beds formed globally during that time. The first of the modern "system" names, it was coined by geologists William Conybeare (geologist), William Conybeare and William Phillips (geologist), William Phillips in 1822, based on a study of the British rock succession. Carboniferous is the per ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Scolopendridae
Scolopendridae (or, in older documents, Scolopendridæ), from Ancient Greek σκόλοψ (''skólops''), meaning "thorn", and ἔντερον (''énteron''), meaning "earthworm", is a family of large centipedes (class Chilopoda). Description Nearly all species in this family have four ocelli ( simple eyes) on each side of the head and only 21 pairs of legs, but there are exceptions: two scolopendrid species feature more legs (''Scolopendropsis bahiensis'', with 21 or 23 leg pairs, and ''S. duplicata'', with 39 or 43 leg pairs), and some scolopendrid species are eyeless and blind (e.g., ''Cormocephalus sagmus'', ''C. pyropygus'', and ''C. delta''). Three Asian members of this family, ''Scolopendra cataracta'', ''Scolopendra paradoxa'', and ''Scolopendra alcyona,'' are known to show amphibious behaviour. Two other species, '' Scolopendra hardwickei'' and '' Hemiscolopendra marginata,'' are known to show sexual dimorphism in the composition of their venom. Genera Subfamily Otostig ...

Monotypic Myriapod 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. Theoretical implications Monotypic taxa present several important theoretical challenges in biological classification. One key issue is known as "Gregg's Paradox": if a single species is the only member of multiple hierarchical levels (for example, being the only species in its genus, which is the only genus in its family), then each level needs a distinct definition to maintain logical structure. Otherwise, the different taxonomic ranks become effectively identical, which creates problems for organizing biological diversity in a hierarchical system. ...
