Tabulate corals consisting of bundles of small (< 1 cm) anastomosing (splitting and recombining) branches

Vine-like splitting and merging patterns with oval- and lens-shaped spaces between thin branches

Alveolites (some species, can also form mounds and branching shapes)

Cladopora (some species have more regular branching)

Tabulate corals consisting of erect bundles of thin (millimeters) tubes (corallites) or clusters of more isolated tiny corallites.

Chain corals; narrow tubes arranged in twisting rows with looping, circular, and polygonal spaces between tubes

Catenipora  Cystihalysites  Halysites   Quepora

Compare with Acinophyllum, a rugose coral with this shape, but thicker corallites

 


Small vine-like shapes, buds, barnacle-like shapes and tiny branching tubes adhering on other fossils

Aulocystis  Chonostegites  Romingeria  

 

Aulopora Cladochonus

Compare with bryozoans, which also have tiny tube-like shapes adhering to other fossils
