Productida is an extinct order of brachiopods in the extinct class
Strophomenata. Members of Productida first appeared during the
Silurian. They represented the most abundant group of brachiopods during the
Permian
The Permian ( ) is a geologic period and System (stratigraphy), stratigraphic system which spans 47 million years from the end of the Carboniferous Period million years ago (Mya), to the beginning of the Triassic Period 251.9 Mya. It is the last ...
period, accounting for 45-70% of all species. The vast majority of species went extinct during the
Permian-Triassic extinction event, though a handful survived into the Early Triassic. Many productids are covered in hollow tubular spines, which are characteristic of the group. A number of functions for the spines have been proposed, including as a defensive mechanism against predators.
