Acad. THE NCBI Taxonomy database allows browsing of the taxonomy tree, which contains a classification of organisms. , a rhynchonellid brachiopod from the Devonian of western Russia (side view). The concave valve was so pervasive among strophomenatans that it must have evolved to perform a function, and I conclude that this was to fill with sediment and conceal these animals in their shallow infaunal mode of life. These brachiopods are stationary epifaunal suspension feeders and have a worldwide distribution. have a pedicle) and the pedicle opening (foramen) is often clearly defined (see image, right). 穿孔贝目（Terebratulida）是腕足动物门具铰纲下的一个目，疹壳，壳多作长卵形，铰合线弯曲，多为双凸型，腹壳具强烈的后转面，三角孔上覆以三角双板，腹壳后方或喙部具大的圆形茎孔。壳面大多光滑，偶有放射饰纹。齿板发育或退化，具腕环。晚志留世至现代，泥盆纪较多，中新生代尤盛。 Jan 1, 2022 · Well visible in most fibers is a striation, indicative of the mode of calcite secretion: deposition of thin layers, increments, of calcite; described in great detail in Simonet Roda et al. g.
