Composita is an extinct brachiopod genus that lived from the Late Devonian to the Late Permian. [1] Composita had a cosmopolitan global distribution, having lived on every continent except Antarctica. [1] [2] Composita had a smooth shell with a more or less distinct fold and sulcus and a round opening for the pedicle on the pedicle valve. Composita is included in the family Athyrididae (Order Athyridida) and placed in the subfamily Spirigerellinae.

Related genera include Cariothyris and Planalvus along with Athyris .

The Indian Creek Massacre occurred on May 21, 1832 with the attack by a party of Native Americans on a group of United States settlers in LaSalle County, Illinois following a dispute about a settler-constructed dam that prevented fish from reaching a nearby Potawatomi village. The incident coincided with the Black Hawk War, but it was not a direct action of the Sauk leader Black Hawk and conflict with the United States. The removal of the dam was asked, was rejected by the settlers and between 40 and 80 Potawatomis and three Sauks attacked and killed fifteen settlers, including women and children. Two young women kidnapped by the Indians were ransomed and released unharmed about two weeks later.

The Craniidae are a family of brachiopods, the only surviving members of the subphylum Craniiformea. They are the only members of the order Craniida, the monotypic suborder Craniidina, and the superfamily Cranioidea; consequently, the latter two taxa are at present redundant and rarely used.There are three living genera within Craniidae: Neoancistrocrania, Novocrania, and Valdiviathyris. As adults, craniids either live freely on the ocean floor or, more commonly, cement themselves onto a hard object with all or part of the ventral valve.

<span class="mw-page-title-main">Brachiopod</span> Phylum of marine animals also known as lamp shells

Brachiopods, phylum Brachiopoda, are a phylum of trochozoan animals that have hard "valves" (shells) on the upper and lower surfaces, unlike the left and right arrangement in bivalve molluscs. Brachiopod valves are hinged at the rear end, while the front can be opened for feeding or closed for protection. Two major categories are traditionally recognized, articulate and inarticulate brachiopods. The word "articulate" is used to describe the tooth-and-groove structures of the valve-hinge which is present in the articulate group, and absent from the inarticulate group. This is the leading diagnostic skeletal feature, by which the two main groups can be readily distinguished as fossils. Articulate brachiopods have toothed hinges and simple, vertically oriented opening and closing muscles. Conversely, inarticulate brachiopods have weak, untoothed hinges and a more complex system of vertical and oblique (diagonal) muscles used to keep the two valves aligned. In many brachiopods, a stalk-like pedicle projects from an opening near the hinge of one of the valves, known as the pedicle or ventral valve. The pedicle, when present, keeps the animal anchored to the seabed but clear of sediment which would obstruct the opening.

<i>Argyrotheca</i> Genus of brachiopods

Argyrotheca is a genus of very small to minute lampshells. All species share a large pedicel opening, one ridge on the inside of the pedunculate valve, pits in a diamond pattern on the inside of both valves, and without radial ridges that end in tubercles. It occurs in depths between 6 and 1300 m. It is known since the latest Cretaceous.
