New data on stromatoporoids of the Northern Pai-Khoi Upper Devonian Lymbada Formation

The papar studies the stromatoporoid association of the middle part of the Upper Devonian Lymbada Formation, of the (interval of marginifera–expansa). The stromatoporoid association is represented by nine species belonging to two orders — Labechiida and Clathrodyctyida. Three species were recorded for the first time in the study area: Labechia polaris Gorsky, Rosenella miniarensis Riab., and Anostylostroma cf. variabile (Riab.). The taxonomic composition of stromatoporoids is similar to that of the Upper Famennian of the Southern, Middle and Northern Urals.
