| The calcareous algae, stromatoporoids, tabulate corals, and rugose corals became conspicuous reef-builders throughout the tropical seas. |
|
| The leaf texture is quilted, or rugose, because the veins are depressed below the surface. |
|
| Nevertheless the rugose corals remained subsidiary components of reefs relative to tabulate corals and stromatoporoids. |
|
| Other fossil groups include diverse rugose corals, some tabulate corals, nautiloids, gastropods, and trilobites. |
|
| It is not known whether rugose corals had symbiotic photosymbiotic zooxanthellae as modern corals do. |
|
| Large underwater reef ecosystems, constructed mainly by rugose and tabulate corals and by stromatoporoids, dramatically vanished. |
|
| With their thicker shells and distinctive internal septae, small solitary rugose corals are easier to see. |
|
| Domal stromatoporoids are present, as are solitary and colonial rugose corals. |
|
| Scientists showed that diseases such as Aucuba mosaic, calico mosaic, latent virus, leaf rolling mosaic, mild mosaic, rugose mosaic, and severe mosaic are viral in nature. |
|
| At this locality, the two stricklandioid species occur mainly in yellowish green, thin-bedded, calcareous mudstone, associated with other brachiopods and rugose corals. |
|
| The Mg content of rugose coral skeletons may thus have varied as a reflection of changing physico-chemical parameters in the marine environment through time. |
|
| Foliage is spindly and very upright, often being a darker green than normal and slightly rugose. |
|
| This rare species might, but for the rugose and pileous epidermis and more depressed form, readily be confounded with the preceding. |
|
| Although these symptoms resemble those caused by citrus leaf rugose ilarvirus or citrus variegation ilarvirus, it was found that these viruses are not associated with citrus chlorotic dwarf. |
|
| Black rotting rugose masses fruiting out of bodies. |
|
| Conspicuous fossils include massive, tabular and stick-like stromatoporoids, tabulate and rugose corals and algae, along with brachiopods, gastropods, bivalves. |
|
| The Tabulata have long been considered to be a group of colonial corals, although they are quite different from the extinct rugose corals and the living hexacorals. |
|
| In particular, the Melanosporum type has a black rugose outer rind, with small warts and black purplish ripening pulp with several white thin veins. |
|
| However, the logs and the MDT tool were not quantitatively effective due to the mud invasion and rugose nature of the wellbore. |
|
| A narrow, rugose basal attachment surface is continuous from the distal basal projection to the apical tip of the medial process. |
|
|
|
| Atrypoidea and colonial rugose corals Entelophyllum are numerous. |
|
| Rugose wood-associated viruses do not appear to be involved in Shiraz decline in South Africa. |
|
| Rugose corals with solitary form, fasciculate colonial form, simple morphology, and high variability also tended to resist the latest Ordovician extinctions. |
