A language family is a group of languages related through descent from a common ancestral language or parental language, called the proto-language of that family. The term "family" reflects the tree model of language origination in historical linguistics, which makes use of a metaphor comparing languages to people in a biological family tree, or in a subsequent modification, to species in a phylogenetic tree of evolutionary taxonomy. Linguists therefore describe the daughter languages within a language family as being genetically related.
The Radiolaria, also called Radiozoa, are protozoa of diameter 0.1–0.2 mm that produce intricate mineral skeletons, typically with a central capsule dividing the cell into the inner and outer portions of endoplasm and ectoplasm. The elaborate mineral skeleton is usually made of silica. They are found as zooplankton throughout the global ocean. As zooplankton, radiolarians are primarily heterotrophic, but many have photosynthetic endosymbionts and are, therefore, considered mixotrophs. The skeletal remains of some types of radiolarians make up a large part of the cover of the ocean floor as siliceous ooze. Due to their rapid change as species and intricate skeletons, radiolarians represent an important diagnostic fossil found from the Cambrian onwards. Some common radiolarian fossils include Actinomma, Heliosphaera and Hexadoridium.
The thrushes are a passerine bird family, Turdidae, with a worldwide distribution. The family was once much larger before biologists determined that the subfamily Saxicolinae, which includes the chats and European robins, are Old World flycatchers. Thrushes are small to medium-sized ground living birds that feed on insects, other invertebrates and fruit. Some unrelated species around the world have been named after thrushes due to their similarity to birds in this family.
Haplorhini, the haplorhines or the "dry-nosed" primates; the Greek name means "simple-nosed") is a suborder of primates containing the tarsiers and the simians, as sister of the Strepsirrhini ("moist-nosed"). The name is sometimes spelled Haplorrhini. The simians include catarrhines, and the platyrrhines.
Commonly "cousin" refers to a "first cousin", a relative whose most recent common ancestor with the subject is a grandparent. More generally, in the lineal kinship system used in the English-speaking world, a cousin is a type of familial relationship in which two relatives are two or more familial generations away from their most recent common ancestor.
Cyrtopera is a genus of radiolarians in the family Theoperidae.
Corallimorpharia is an order of marine cnidarians closely related to stony or reef building corals (Scleractinia). They occur in both temperate and tropical climates, although they are mostly tropical. Temperate forms tend to be very robust, with wide and long columns, whereas tropical forms tend to have very short columns with a wide oral disc and very short tentacles. The tentacles are usually arranged in rows radiating from the mouth. Many species occur together in large groups, although there are recorded instances of individuals. In many respects, they resemble the stony corals, except for the absence of a stony skeleton. Morphological and molecular evidence suggests that they are very closely related to stony corals.
The Schrambach Formation is a geologic formation in the Northern Limestone Alps of Austria and Germany. It preserves fossils dating back to the Early Cretaceous period.
The Tauglboden Formation is a geologic formation in Tirol, Austria. It preserves fossils dating back to the Oxfordian stage of the Jurassic period. The radiolarites were deposited in a deep marine environment.
Heinz Walter Kozur was a German paleontologist and stratigrapher.
Cornutella is a genus of radiolarians in the family Theoperidae. C. clathrata, the type species, was described from the Miocene of Caltanisetta, Sicily.

Cenellipsis is a genus of radiolarians in the order Spumellaria. The genus is extant but there are also fossil species.
Castanidium elegans is a species of cercozoans in the family Castanellidae. It is found in the Sargasso Sea and in the current around the Canary Islands.
"Monothalamea" is a grouping of foraminiferans, traditionally consisting of all foraminifera with single-chambered tests. Recent work has shown that the grouping is paraphyletic, and as such does not constitute a natural group; nonetheless, the name "monothalamea" continues to be used by foraminifera workers out of convenience.
Clathrocyclas is a genus of radiolarians in the family Theoperidae.
Clathrocyclas elegans is a species of radiolarians in the family Theoperidae.
Cornutanna is a genus of radiolarians in the order Nassellaria.
