PHYLUM CNIDARIA - CLASS ANTHOZOA The Phylum Cnidaria includes corals, jellyfish, and sea anemones. Fossil specimens representing a wide variety of this phylum have been discovered, but it is Class Anthozoa - the corals - that interest us most, due to the enhanced preservation of their hard skeletal …The Tabulata were much less variable than rugose or scleractinian corals. They were all colonial and consisted of slender tube-like corallites 1-3 mm diameter, crossed internally by transverse partitions, the tabulae. Colonies were typically encrusting, flat or massive, but may have also been branching.Comparison of the three Siphonodendron coral biostromes in NW Ireland. Biostrome. Pauciradiale biostrome.

Carboniferous terrestrial environments were dominated by vascular land plants ranging from small, shrubby growths to trees exceeding heights of 100 feet (30 metres). The most important groups were the lycopods, sphenopsids, cordaites, seed ferns, and true ferns.Lysopods are represented in the modern world only by club mosses, but in the …The symmetry in rugose is bilateral, meaning that two identical halves can be created, humans are bilaterally symmetrical.

This report presents a quantitative analysis of the late Visean coral assemblages from ... Palaeozoic rugose corals with calcite skeletons, like this Grewingkia canadensis, are doubtfully ancestors of the Scleractinia.

Scleractinian ("hard-rayed") corals first appeared in the Middle Triassic and refilled the ecological niche once held by tabulate and rugose corals.
