The caudal ramus (plural: caudal rami) is a characteristic feature of primitive crustaceans. Located on the anal somite (telson segment), the caudal ramus is a pair of appendage-like or spine-like protrusions. Specific structures which are rod or blade-like are referred to as caudal furca .
Uniramia is a group within the arthropods. In the past this group included the Onychophora, which are now considered a separate category. The group is currently used in a narrower sense.
The coelom is the main body cavity in most animals and is positioned inside the body to surround and contain the digestive tract and other organs. In some animals, it is lined with mesothelium. In other animals, such as molluscs, it remains undifferentiated. In the past, and for practical purposes, coelom characteristics have been used to classify bilaterian animal phyla into informal groups.
Xiphosura is an order of arthropods related to arachnids. They are sometimes called horseshoe crabs. They first appeared in the Hirnantian. Currently, there are only four living species. Xiphosura contains one suborder, Xiphosurida, and several stem-genera.
The telson is the posterior-most division of the body of an arthropod. Depending on the definition, the telson is either considered to be the final segment of the arthropod body, or an additional division that is not a true segment on account of not arising in the embryo from teloblast areas as other segments. It never carries any appendages, but a forked "tail" called the caudal furca may be present. The shape and composition of the telson differs between arthropod groups.
Giovanni Brusca is an Italian mobster and former member of the Corleonesi clan of the Sicilian Mafia. He had a major role in the 1992 murders of Antimafia Commission prosecutor Giovanni Falcone and businessman Ignazio Salvo, and once stated that he had committed between 100 and 200 murders. Brusca had been sentenced to life imprisonment in absentia for Mafia association and multiple murder. He was captured in 1996, turned pentito, and his sentence reduced to 26 years in prison. In 2021, Brusca was released from prison.
The Ramu River is a major river in northern Papua New Guinea. The headwaters of the river are formed in the Kratke Range from where it then travels about 640 km (398 mi) northwest to the Bismarck Sea.
Mesoglea refers to the tissue found in cnidarians like coral or jellyfish that functions as a hydrostatic skeleton. It is related to but distinct from mesohyl, which generally refers to tissue found in sponges.
The Sepik or Sepik River languages are a family of some 50 Papuan languages spoken in the Sepik river basin of northern Papua New Guinea, proposed by Donald Laycock in 1965 in a somewhat more limited form than presented here. They tend to have simple phonologies, with few consonants or vowels and usually no tones.
In vertebrates, the pubic bone is the most forward-facing of the three main bones making up the pelvis. The left and right pubic bones are each made up of three sections, a superior ramus, inferior ramus, and a body.
Dasygnathoides is an extinct genus of pseudosuchian from the Late Triassic (Carnian) Lossiemouth Sandstone of Scotland.
This glossary of ichthyology is a list of definitions of terms and concepts used in ichthyology, the study of fishes.
Banji is an extinct genus of oviraptorid dinosaur that lived approximately 66 million years ago during the later part of the Cretaceous Period in what is now China. It was a small, lightly-built, ground-dwelling, bipedal carnivore, that was an estimated 65 cm (2.1 ft) long, as a juvenile.
Sinornis is a genus of enantiornithean birds from the Lower Cretaceous Jiufotang Formation of the People's Republic of China.
The Grass languages are a group of languages in the Ramu language family. It is accepted by Foley (2018), but not by Glottolog. They are spoken in East Sepik Province, Papua New Guinea, with a small number of speakers also located just across the provincial border in Madang Province.
Polonosuchus is a genus of rauisuchid known from the late Triassic of Poland. It was a huge predator about 5–6 metres in length and, like all rauisuchians, was equipped with a large head of long sharp teeth. The legs were placed almost underneath the body, unlike most reptiles, which would have made it quite fast and a powerful runner. The appearance was very similar to that of the more known Postosuchus, of North America, and shared with the latter the ecological niche of the apex predator.
The Lower Ramu or Ottilien–Misegian languages consist of two branches in the Ramu language family. They are all spoken in Yawar Rural LLG, Madang Province, Papua New Guinea.
Ratchasimasaurus is a genus of iguanodontian ornithopod dinosaur from Early Cretaceous Khok Kruat Formation of Nakhon Ratchasima Province in northeastern Thailand. The type and only species is R. suranareae, named after Thao Suranari, a 19th-century war heroine. It was considered by one study to be a nomen dubium, diagnosed with characters widespread in Styracosterna.
Longusunguis is an extinct genus of bohaiornithid enantiornithean dinosaur known from the Early Cretaceous of Liaoning Province, northeastern China. It contains a single species, Longusunguis kurochkini.
Spectrovenator is a genus of basal abelisaurid theropod dinosaur that lived during the early Cretaceous period in what is now Brazil. It is known by a single species, S. ragei, recovered from the Quiricó Formation.
Pentanogmius is an extinct genus of sail-finned ray-finned fish that lived during the Late Cretaceous in what is now Europe and the USA. Five species are currently recognized, 2 from Cenomanian to Turonian Europe and 3 better known species from Coniacian to Campanian North America. The American species inhabited large areas of the Western Interior Seaway, with fossil finds indicating a range from Texas and Alabama in the south to Manitoba, Canada, in the north.
