Evolution of Paleobiocommunities Is One of the Most Intractable Problems of Biostratigraphy
摘要
Abstract
The biostratigraphic data accumulated to date on the subdivision of the Phanerozoic marine sequences make it possible to interpret the evolution features of not only low-ranking biotic taxa but also paleocommunities (assemblages), which can be considered as biotic groupings historically formed under certain conditions. Examples of their evolution stages in various Geomerida marine ecosystems are given. The opinion is stated about the need to intensify the research on this topic with the involvement of both geologists and biologists.
