... and septal arrangement during the course of hystero-ontogeny. However, this symmetry results only from structural necessity and is transitory. It is not homologous with the bilaterality of body plans characteristic of anthozoan groups. The morphological simplicity, related parricidal reproduction...

... plan is broadly comparable to that of anthozoan cnidarians, minus such derived features as muscle, tentacles and a centralized mouth. Along with other early bag-like fossils, rangeomorphs can be reliably identified as total-group eumetazoans, potentially colonial stem-group cnidarians. Laflamme et...

... INTRODUCTION The term coral as used here includes the living and extinct groups of coelenterates possessing calcareous skeletons: hydrozoans: milleporids, stylasterids, and stromatoporids; anthozoans: Scleractinia, Rugosa, and Tabulata; and a few alcyonarians such as Heliopora...

...). Probable anthozoan-polychaete mutualism has been suggested based on trace fossils. Pacześna (2010) described a discernible longitudinal polychaete burrow is coiled around the cylindrical shaft of a plug-shaped trace fossil of a probable sea anemone. This association is known only from Cambrian Series 2...

... ). As expected, we find strong support for the monophyly of triploblasts, those bilaterians possessing true mesoderm. Recent studies on cnidarians have demonstrated that mesoderm is a triploblast apomorphy because “mesoderm” genes are expressed in the endoderm of the anthozoan Nematostella ( Scholtz...

..., and their paleoenvironmental and paleoecological implications are addressed. Trace fossils occur as dense populations that precede the earliest occurrences of Skolithos pipe rock in the region. These trace fossils are assigned to the ichnogenera Bergaueria, Conichnus, and Dolopichnus, and each represents the burrowing...

... Silurian recovery. Using a database of genus occurrences for inarticulate and articulate brachiopods, bivalves, anthozoans, and trilobites, we show that sampling-standardized diversity trends differ for the three regions. Diversity rebounded to pre-extinction levels within 5 Myr in the paleocontinent...

... (Tomašových, 2006), abundance studies within the Middle and Late Triassic are still largely neglected. Many questions have been left unanswered, for example, What are the associated paleoecological details of this transition period? Are two major Phanerozoic events linked, and if so, how? Undoubtedly...

There is also a broad change in the faunal composition with echinoderms and trilobites more common in the west and conulariids, anthozoans, and hyolithids more common in the east ( Oosthuizen 1984 ).
