Odontochile
''Odontochile'' is a genus of trilobites in the order Phacopida, family Dalmanitidae.Struve, W. Suborder Phacopina, p. O471-O472. ''in'' Moore, R.C. (ed.). Treatise on Invertebrate Paleontology. Part O – Arthropoda (Trilobitomorpha). 1959 These trilobites were fast-moving low-level epifauna and detritivore. They lived in the Devonian period, from 414 to 391 million years ago. Distribution Silurian of China; Silurian to Devonian of Australia and the United States; Devonian of Algeria, Canada, the Czech Republic, France, Germany, Kazakhstan, Morocco and Spain. Description ''Odontochile'' is genus of trilobites with a large (about long), moderately vaulted exoskeleton with an inverted egg-shaped outline (about 1.6× longer than wide). Its headshield (or cephalon) is semicircular, with long (genal) spines extending from the side of the cephalon back to the tailshield (or pygidium). The frontal margin of the cephalon is semicircular to parabolic, and lacks an anterior exten ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Phacopina
The Phacopina comprise a suborder of the trilobite order Phacopida. Species belonging to the Phacopina lived from the Lower Ordovician (Tremadocian) through the end of the Upper Devonian (Famennian).Moore, R.C. (ed.). Treatise on Invertebrate Paleontology. Part O – Arthropoda (Trilobitomorpha). 1959 The one unique feature that distinguishes Phacopina from all other trilobites are the very large, separately set lenses without a common cornea of the compound eye. Habitat As far as known, all Phacopina species were marine bottom-dwellers. Origin The Early Ordovician genus '' Gyrometopus'' (superfamily Dalmanitoidea, family Diaphanometopidae) is probably close to the common ancestor of the Phacopina. ''Gyrometopus'' is phacopid in appearance, but a rostral plate is present, unlike in other Phacopina. However, the rostral plate does not divide the cephalic doublure into a left and right section, but instead the rostral suture defines a semicircle in the frontal ¾ of the doublur ...

Dalmanitidae
Dalmanitidae is a family of trilobites in the order Phacopida that lived from the Floian The Floian is the second stage of the Ordovician Period. It succeeds the Tremadocian with which it forms the Lower Ordovician epoch. It precedes the Dapingian Stage of the Middle Ordovician. The Floian extended from to million years ago. The ...

Francovichia
''Francovichia'' is a trilobite in the order Phacopida (family Dalmanitidae), that existed during the lower Devonian in what is now Bolivia. It was described by Branisa and Vanek in 1973, and the type species is ''Francovichia branisi'', which was originally described under the genus ''Odontochile'' by Wolfart in 1968. It also contains the species, ''F. clarkei''. The type locality was the Belén Formation. P.A. Jell and J.M. Adrain. References External links ''Francovichia'' at the |
Animal
Animals are multicellular, eukaryotic organisms in the Kingdom (biology), biological kingdom Animalia. With few exceptions, animals Heterotroph, consume organic material, Cellular respiration#Aerobic respiration, breathe oxygen, are Motility, able to move, can Sexual reproduction, reproduce sexually, and go through an ontogenetic stage in which their body consists of a hollow sphere of Cell (biology), cells, the blastula, during Embryogenesis, embryonic development. Over 1.5 million Extant taxon, living animal species have been Species description, described—of which around 1 million are Insecta, insects—but it has been estimated there are over 7 million animal species in total. Animals range in length from to . They have Ecology, complex interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as zoology. Most living animal species are in Bilateria, a clade whose members have a Symmetry in biology#Bilate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Silurian Trilobites Of Asia
The Silurian ( ) is a geologic period and system spanning 24.6 million years from the end of the Ordovician Period, at million years ago ( Mya), to the beginning of the Devonian Period, Mya. The Silurian is the shortest period of the Paleozoic Era. As with other geologic periods, the rock beds that define the period's start and end are well identified, but the exact dates are uncertain by a few million years. The base of the Silurian is set at a series of major Ordovician–Silurian extinction events when up to 60% of marine genera were wiped out. One important event in this period was the initial establishment of terrestrial life in what is known as the Silurian-Devonian Terrestrial Revolution: vascular plants emerged from more primitive land plants, dikaryan fungi started expanding and diversifying along with glomeromycotan fungi, and three groups of arthropods (myriapods, arachnids and hexapods) became fully terrestrialized.
