Summary[edit]
| Description |
English: Micro-CT models of radiolarians from the Middle Ordovician Piccadilly Formation A compilation of line drawings and micro-CT models of various radiolarians from the Middle Ordovician Piccadilly Formation, western Newfoundland with the innermost sphere highlighted (red). Each segment is shown at the same scale. (a) micro-CT models of Haplotaeniatum sp. cf. H. vertigospongum (Jones and Noble) capturing the complex spiral growth of the skeleton. (b) Triplococcus acanthicus Danelian and Popov demonstrating a complete morphological observation of the relationship between spheres and spines without compromising the integrity of the specimen. (c) Undescribed new species of the genus Westernbrookia demonstrating a primitive tetrahedral initial spicule similar to that of Triassic. See: Dumitrica, P. Pyloctostylus n. gen., a Cretaceous Spumellarian radiolarian genus with initial spicule. Revue de Micropaléontologie 37, 235–244 (1994). |
