Beds with conodonts also yield fusulinids that is suitable for refining correlation of conodont and fusulinid zonations. Stratigraphic ranges of different conodont species in the Bage-Vang section ...Define evolution. How does evolution explain both the unity and the diversity of life? Evolution is considered a unifying theory of biology. It explains the unity and diversity of life. 1)Descents from a common ancestor explain the unity of life. 2) the unity of life = living things share a common chemistry and cellular structure (DNA, RNA and ... The Fusulinida is an extinct order within the Foraminifera in which the tests are traditionally considered to have been composed of microgranular calcite.They indicated that the conodonts, fusilinids, and ammonoids at that location are Early Permian (Asselian). On the basis of a collection of more than 40,000 ammonoids, Emilites is numerically a relatively unimportant component of Upper Pennsylvanian ammonoid assemblages.

In summary, the test walls of the studied large, fusiform fusulinids contain two layers with different textures: a microgranular texture making up the main part of the test (keriotheca) and a nanogranular outer lining (tectum). The keriotheca is composed of tightly fitting equidimensional (1 to 2 μm in diameter) brick-like primary elements ...

Many species of wild animals, including the Tibetan antelope, kiang, yak, and hare, inhabit the plateau, which has an average …Our findings provide new insights into the biomineralization style and affinities of Paleozoic “fusulinid” foraminifera, and invalidate the “microgranular fusulinids” paradigm. ResultsThe Fusulinida is an extinct order within the Foraminifera in which the tests (shells) are composed of tightly packed, secreted microgranular calcite. Like all Forams, they are single-celled organisms. In advanced forms the test wall is differentiated into two or more layers. Loeblich and Tappan, 1988, gives a range from the Lower Silurian to the Upper Permian, with the fusulinid foraminifera ...

The Permian Period was a critical time interval during which various blocks of the Qinghai-Tibetan Plateau have experienced profound and complex paleogeographical changes. The supercontinent Pangea was formed to its maximum during this interval, hampering a global east-to-west trending equatorial warm ocean current. Meanwhile, a …
