[Note: Synonyms include only those forms sufficiently well illustrated and described to permit determination of significant features.]. Start The thin regularly spaced tabulae rise gradually from the periphery and then curve gently downward. These corals and the Permian species M. kansasense are characterized by very rapid development of the corallite and restriction of internal structures to the lower part.

The genotype of Lophophyllidium was designated as Lophophyllum proliferum (McChesney) by Grabau (1928, p. 99) in the original description of the genus, but some differences in interpretation of the type have developed.

The counter septum is extended to the axis to form the column in all except the very mature stages and then remains longer than other septa. [not] Cyathaxonia prolifera Foerste, 1887, Denison Univ. Bivalves and brachiopods are both sessile filter feeders, sitting on the seafloor and filtering water for food and oxygen. This form is also given by Chi (1938, p. 161) as the "genolectotype" of Lophophyllidium. Diverse early endobiotic coral symbiont assemblage from the Katian (Late Ordovician) of Baltica. NewDinosaurs.com, 2023. The curvature of the corallite in the Permian species is in the plane of the alar septa whereas the cardinal septum lies on the concave side of the corallite in L. proliferum. In external details the lophophyllids from the Worthen collection show much similarity to the illustrations given by McChesney. 13, fig.

Index fossils Facts for Kids - Kiddle A, and L. sp, B, differ from others referred to this genus in the restriction of the immature characters to a very small part of the apical region, the scarcity or absence of tabulae, and the large alar pseudofossulae. Also known as guide fossils, indicator fossils, or zone fossils, they are used to identify periods of geological time. The thickening of septa and deposition of stereoplasm in the lower half of the corallite conceals most of the details of this part. The Middle Ordovician of the Oslo Region, Norway: 2.
