Acalypha is a genus of flowering plants in the family Euphorbiaceae. It is the sole genus of the subtribe Acalyphinae. It is one of the largest euphorb genera, with approximately 450 to 462 species. The genus name Acalypha is from the Ancient Greek ἀκαλύφη (akalúphē) ("nettle"), an alternative form of ἀκαλήφη (akalḗphē), and was inspired by the nettle-like leaves. General common names include copperleaf and three-seeded mercury. Native North American species are generally inconspicuous most of the year until the fall when their stems and foliage turn a distinctive coppery-red.

The genus is distributed mainly in the tropics and subtropics, with about 60% of species native to the Americas and about 30% in Africa.


Alchornea is a plant genus of the family Euphorbiaceae first described as a genus in 1788. It is widespread in tropical and subtropical regions of Africa, S Asia, Australia, Latin America, and various oceanic islands. Molecular phylogenetic analyses suggest that Bocquillonia from New Caledonia is nested in Alchornea.

The Amiiformes order of fish has only one extant species, the bowfin (Amia calva).


Brancasaurus (meaning "Branca's lizard") is a genus of plesiosaur which lived in a freshwater lake in the Early Cretaceous of what is now North Rhine-Westphalia, Germany. With a long neck possessing vertebrae bearing distinctively-shaped "shark fin"-shaped neural spines, and a relatively small and pointed head, Brancasaurus is superficially similar to Elasmosaurus, albeit smaller in size at 3.26 metres (10.7 ft) in length.

The type species of this genus is Brancasaurus brancai, first named by Theodor Wegner in 1914 in honor of German paleontologist Wilhelm von Branca. Another plesiosaur named from the same region, Gronausaurus wegneri, most likely represents a synonym of this genus. While traditionally considered as a basal member of the Elasmosauridae, Brancasaurus has more recently been recovered as a member, or close relative, of the Leptocleididae, a group containing many other freshwater plesiosaurs.

Castro culture

Castro culture (Galician: cultura castrexa, Portuguese: cultura castreja, Asturian: cultura castriega, Spanish: cultura castreña) is the archaeological term for the material culture of the north-western regions of the Iberian Peninsula (present-day northern Portugal together with Galicia, Asturias, Castile and León, Cantabria and Basque Country) from the end of the Bronze Age (c. 9th century BC) until it was subsumed by Roman culture (c. 1st century BC).

It is the culture associated with the Celtiberians, closely associated to the western Hallstatt horizon of Central Europe.

The most notable characteristics of this culture are: its walled oppida and hill forts, known locally as castros, from Latin castrum "castle", and the scarcity of visible burial practices, in spite of the frequent depositions of prestige items and goods, swords and other metallic riches in rocky outcrops, rivers and other aquatic contexts since the Atlantic Bronze Age. This cultural area extended east to the Cares river and south into the lower Douro river valley.

The area of Ave Valley was the core region of this culture, with a large number of small Castro settlements, but also including larger oppida, the cividades (from Latin civitas, city), some known as citânias by archaeologists, due to their city-like structure: Cividade de Bagunte (Civitas Bogonti), Cividade de Terroso (Civitas Terroso), Citânia de Briteiros, and Citânia de Sanfins.

Europasaurus is a basal macronarian sauropod, a form of quadrupedal herbivorous dinosaur. It lived during the Late Jurassic (middle Kimmeridgian, about 154 million years ago) of northern Germany, and has been identified as an example of insular dwarfism resulting from the isolation of a sauropod population on an island within the Lower Saxony basin.

Gunung Ambang Nature Reserve

Gunung Ambang Nature Reserve is a preserved area in the north of the island of Sulawesi in Indonesia. It is in a mountainous, little-explored region and contains a large number of indigenous plants and animals.

Kimmeridge Clay

The Kimmeridge Clay is a sedimentary deposit of fossiliferous marine clay which is of Late Jurassic to lowermost Cretaceous age and occurs in southern and eastern England and in the North Sea. This rock formation is the major source rock for North Sea oil. The fossil fauna of the Kimmeridge Clay includes turtles, crocodiles, sauropods, plesiosaurs, pliosaurs and ichthyosaurs, as well as a number of invertebrate species.


Knoetschkesuchus is a genus of small atoposaurid crocodylomorph from the Late Jurassic of Germany and Portugal. Two species are known: the German species K. langenbergensis, described by Schwarz and colleagues in 2017 based on two partial skeletons and various isolated bones; and the Portuguese species K. guimarotae, named from over 400 specimens including several partial skeletons. Knoetschkesuchus was a small and short-snouted crocodilian, measuring about 55 centimetres (22 in) in length, that primarily fed on small prey, including invertebrates, amphibians, and mammals. This specialization towards small prey ecologically separated Knoetschkesuchus from most of the other diverse crocodilians that it lived with in the island ecosystem of Jurassic Europe.

Both species were formerly recognized as belonging to Theriosuchus; K. guimarotae was initially named as T. guimarotae, and specimens of K. langenbergensis were initially referred to T. pusillus upon their discovery. Schwarz and colleagues recognized a number of characteristics that united these two taxa to the exclusion of other species of Theriosuchus; in particular, Knoetschkesuchus only has two distinct types of teeth, lacking the leaf-shaped teeth seen in other atoposaurids. Other distinguishing traits include the relatively wide skull, and the presence of the antorbital and mandibular fenestrae in all life stages.

List of Euphorbiaceae genera

Here is a full taxonomy of the family Euphorbiaceae, according to the most recent molecular research. This complex family previously comprising 5 subfamilies: the Acalyphoideae, the Crotonoideae, the Euphorbioideae, the Phyllanthoideae and the Oldfieldioideae. The 3 first ones are uni-ovulate families while the 2 last one are bi-ovulate.

Now the Euphorbiaceae has been split into 5 families: The 3 uni-ovulate subfamilies have become the Euphorbiaceae in the strict sense, with the tribe Galearieae in the Acalyphoideae forming the most of the family Pandaceae. Part of the bi-ovulate subfamily Phyllanthoideae has become the family Phyllanthaceae, with the tribe Drypeteae as family Putranjivaceae and the tribe Centroplaceae part of the Pandaceae. The other bi-ovulate subfamily Oldfieldioideae has become the Picrodendraceae.

List of prehistoric bony fish genera

This List of prehistoric bony fish is an attempt to create a comprehensive listing of all genera from the fossil record that have ever been considered to be bony fish (class osteichthyes), excluding purely vernacular terms. The list includes all commonly accepted genera, but also genera that are now considered invalid, doubtful (nomina dubia), or were not formally published (nomina nuda), as well as junior synonyms of more established names, and genera that are no longer considered members of osteichthyes.

This list includes 1,386 generic names.

Extinct genera are marked with a dagger (†).

Extant genera are bolded.

Luoxiongichthys is an extinct genus of basal actinopterygian (ray-finned fish) known from the lower Middle Triassic (Pelsonian substage, Anisian stage) of Luoxiong Town, Luoping County of Yunnan Province, southwestern China. It is known from the holotype LPV-10144, which consists of nearly complete skeleton and skull, from the paratype LPV-10120, a partial skull and from the referred materials LPV-10625, LPV-6868 and LPV-11817. It was found in the new Middle Triassic Lagerstätte of the Guanling Formation, Member II. It was first named by Wen Wen, Qi-Yue Zhang, Chang-Yong Zhou, Jin-Yuan Huang, Zhong Qiang Chen and Michael J. Benton in 2011 and the type species is Luoxiongichthys hyperdorsalis. The generic name is derived from Luoxiong Town, where the specimens were found and ichthys, "fish" from Greek. The specific name comes from hyper, "over" and dorsalis, "of the back" from Greek in reference to its elevated "hump" in front of the dorsal fin.


Pachycormidae is an extinct family of ray-finned fish known from Mesozoic deposits from Eurasia and the Americas. They were characterized by having serrated pectoral fins, reduced pelvic fins and a bony rostrum. Certain members of the group were large filter-feeding planktivores. Their relations with other fish are unclear.
