Productida is an extinct order of brachiopods in the extinct class Strophomenata. Members of Productida first appeared during the Silurian.[1] They represented the most abundant group of brachiopods during the Permian 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.[2] 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.[3]

Produktīdu kārta ( Latvian )

provided by wikipedia LV

Produktīdu kārta (Productida) ir slēdzenes pleckāju kārta. Čaulas pseidoporainas, ieliekti-izliektas retāk plakani izliektas. Arejas uz čaulas vāciņiem var būt un var arī nebūt. Čauliņu ornamentējums ir daudzveidīgs. Uz viena vai abiem vāciņiem, kā arī gar slēdzes malu ir dobas adatas. Ja vēdera čauliņai ir zobi, tad tie ir bez zobu plātnēm. Rokas aparāta un ar to saistīto struktūru produktīdiem nav. Čaulai ir branhiālie nospiedumi un sarežģītas uzbūves atslēgas izaugums. Produktīdu kārtas pārstāvji dzīvoja no silura līdz permam.

Sistemātika

Senāk Strofomenīdu kārtu iedalīja 3 virsdzimtās: Chonetacea, Productacea, Lyttoniacea. Tagad kārtu veido ir četras apakškārtas.
