Abstract

Giant brachiopods, including representatives of the order Chonetida, appeared in the second half of the Tournaisian and in the Viséan (Early Carboniferous). Based on known gigantism in extant organisms, the origin of this phenomenon can be associated with the maximum of a large Early Carboniferous transgression, which caused deepening of marine basins and a decrease in the temperature of the bottom water layers.

石炭纪早期腕足纲的巨人症

摘要

巨型腕足类动物，包括 Chonetida 目的代表，出现在 Tournaisian 的后半期和 Viséan（早石炭世）。根据现存生物已知的巨型现象，这种现象的起源可能与早期石炭纪大型海侵的最大值有关，这导致海盆加深和底水层温度降低。
