The present time resolution in terms of ammonoid biostratigraphy is highest in the Devonian (one zone has a mean of 0.9 Ma) and in the Carboniferous (about 1 Ma), while the subdivision of the Permian is much coarser (about 2.5 Ma per ammonoid zone on average).简洁 发表于 2025-3-23 18:52:20

https://doi.org/10.1007/978-3-662-61436-5sic age produced an empirical morphospace this time interval. The morphospace of Paleozoic ammonoids shows some subtle changes between the periods, but generally, the occupied area is remarkably similar.bifurcate 发表于 2025-3-25 02:16:57
