| Calcareous microgranular and porcellaneous tests evolved in the Carboniferous, and calcareous hyaline tests in the Permian. |
|
| It is found as pale yellow, chalky to porcellaneous masses to 3 cm in size or as chalky films in the conglomerate. |
|
| Only very fine-grained facies referred to as porcellaneous have provided biostratigraphically indicative fauna, i.e. calpionellids. |
|
| One of the many highlights of the thirty-five-strong display is an unusual porcellaneous stoneware pillow in the shape of a reclining boy shaded by a lotus leaf. |
|
| This soon rejoins the main passage, and before long the floor breaks through the porcellaneous band, and the passage develops into a somewhat more pleasant vadose trench. |
|
| For example, some Triassic cornuspirids appear to possess a microgranular wall rather than a porcellaneous wall, and thus could be classified as Fusulinida. |
|
| This arrangement gives milioline tests a porcellaneous appearance. |
