Branching Tabulate Coral is a marine animal. The individual … These families are all distinctive and, morphologically, the multi-species families listed above appear to be monophyletic. As expected, branching coral substrates have high rugosities at the smaller spatial scales, at which the complexity of the branching network plays a role. Originally, the network provided a group of geologists who served as resource persons for teachers. 0000009580 00000 n Massive and laminar tabulate corals, crinoids, ostracods, bryozoans, brachiopods and trilobites are also observed.
