Lichas is a genus of lichid trilobites from Ordovician-Devonian-aged marine strata of Europe and Morocco. [1] [2]
Agnostida is an order of arthropod which first developed near the end of the Early Cambrian period and thrived during the Middle Cambrian. They are present in the Lower Cambrian fossil record along with trilobites from the Redlichiida, Corynexochida, and Ptychopariida orders. The last agnostids went extinct in the Late Ordovician.
The Ordovician is a geologic period and system, the second of six periods of the Paleozoic Era. The Ordovician spans 41.6 million years from the end of the Cambrian Period 485.4 million years ago (Mya) to the start of the Silurian Period 443.8 Mya.
Trilobites are a group of extinct marine artiopodan arthropods that form the class Trilobita. Trilobites form one of the earliest-known groups of arthropods. The first appearance of trilobites in the fossil record defines the base of the Atdabanian stage of the Early Cambrian period, and they flourished throughout the lower Paleozoic before slipping into a long decline, when, during the Devonian, all trilobite orders except the Proetida died out. The last extant trilobites finally disappeared in the mass extinction at the end of the Permian about 252 million years ago. Trilobites were among the most successful of all early animals, existing in oceans for almost 300 million years.
In Greek mythology, Lichas was Heracles' servant, who brought the poisoned shirt from Deianira to Hercules because of Deianira's jealousy of Iole, which killed him.
The Dalatiidae are the family of kitefin sharks of the order Squaliformes. Members of this family are small, under 2 m (6.6 ft) long, and are found worldwide. They have cigar-shaped bodies with narrow heads and rounded snouts. Several species have specialized bioluminescent organs. Though eight genera are in this family, four of them are monotypic.
Asaphida is a large, morphologically diverse order of trilobites found in marine strata dated from the Middle Cambrian until their extinction during the Silurian. Asaphida contains six superfamilies, but no suborders. Asaphids comprise some 20% of described fossil trilobites.
Phacopida ("lens-face") is an order of trilobite that lived from the Late Cambrian to the Late Devonian. It is made up of a morphologically diverse group of related suborders.
Women of Trachis or The Trachiniae c. 450–425 BC, is an Athenian tragedy by Sophocles.
Lichida is an order of typically spiny trilobite that lived from the Furongian to the Devonian period. These trilobites usually have 8–13 thoracic segments. Their exoskeletons often have a grainy texture or have wart or spine-like tubercles. Some species are extraordinarily spiny, having spiny thoracic segments that are as long or longer than the entire body, from cephalon (head) to pygidium (tail). The sections of the pygidia are leaf-like in shape and also typically end in spines.
The Ludlow Group are geologic formations deposited during the Ludlow epoch of the Silurian period in the British Isles, in areas of England, Ireland, Scotland, and Wales.
The kitefin shark or seal shark is a species of squaliform shark in the family Dalatiidae, and the only species in its genus. It is found sporadically around the world, usually close to the sea floor at depths of 200–600 m (660–1,970 ft). With a sizable oil-filled liver to maintain neutral buoyancy, this shark is able to cruise slowly through the water while expending little energy. The kitefin shark has a slender body with a very short, blunt snout, large eyes, and thick lips. Its teeth are highly differentiated between the upper and lower jaws, with the upper teeth small and narrow and the lower teeth large, triangular, and serrated. Its typical length is 1.0–1.4 m (3.3–4.6 ft).
Arachnomorpha is a subdivision or clade of Arthropoda, comprising the monophyletic group formed by the trilobites, other great appendage arthropods and trilobite-like families, and a diverse sister clade including the chelicerates. Great debate is held on the position of the Pycnogonida, which are currently thought not to be placed in the immediate vicinity of the Chelicerata. Arachnomorpha are considered the sister group to the crustaceans, which are increasingly being accepted as members of the mandibulate clade.
Hercules is a Musical Drama in three acts by George Frideric Handel, composed in July and August 1744. The English language libretto was by the Reverend Thomas Broughton, based on Sophocles's Women of Trachis and the ninth book of Ovid's Metamorphoses.
Licha is a monotypic moth genus of the family Noctuidae. Its only species, Licha undilinealis, is found in Venezuela and the Brazilian state of Rio de Janeiro. Both the genus and species were first described by Francis Walker in 1859.
The cephalon is the head section of an arthropod. It is a tagma, i.e., a specialized grouping of arthropod segments. The word cephalon derives from the Greek κεφαλή (kephalē), meaning "head".
María Fernanda García is a Mexican actress best known as "Licha" in Una familia de diez. She has also appeared in many telenovelas and won a Silver Ariel for "Best Actress in a Minor Role" for the film Bienvenido — Welcome (1995) at the 37th Ariel Awards.
Entomostracites is a scientific name for several trilobites, now assigned to various other genera.
Lichah is a village in Jirhandeh-ye Lasht-e Nesha Rural District, Lasht-e Nesha District, Rasht County, Gilan Province, Iran. At the 2006 census, its population was 1,623, in 498 families.
The Player is a 1953 Mexican crime film directed by Vicente Oroná and starring David Silva, Carmelita González and Aurora Segura.
Metacryphaeus is an extinct genus of trilobites from the family Calmoniidae. Metacryphaeus fossils have been found in Bolivia, Brazil, South Africa and Uruguay. The genus was named in 1907.
