| The calcareous algae, stromatoporoids, tabulate corals, and rugose corals became conspicuous reef-builders throughout the tropical seas. |
|
| Other faunal elements include colonial and solitary corals, encrusting bryozoans, stromatoporoids, and rare brachiopods. |
|
| The stromatoporoids had massive calcareous skeletons that are preserved as rather conspicuous fossils. |
|
| Nevertheless the rugose corals remained subsidiary components of reefs relative to tabulate corals and stromatoporoids. |
|
| However, in many reefal carbonates stromatoporoids are the only recognizable fossils available to the biostratigrapher. |
|
| In the columns of rock and on the floors of the caves lie fossil sponges, the stromatoporoids, and the curled-up shells of ammonites. |
|
| In a general article on reef succession, Copper noted the role of stromatoporoids in the climax phase of Silurian and Devonian reefs. |
|
| There are two main groups of fossil stromatoporoids that lived in different eras, the Paleozoic and the Mesozoic. |
|
| Other marine fossils commonly found throughout the Silurian record include trilobites, graptolites, conodonts, corals, stromatoporoids, and mollusks. |
|
| Stromatoporoids with maculate microstructure constituted the family Stromatoporidae, whereas those with more solid-looking microstructure constituted four other families. |
