Stromatoporoids from the allochthonous reef facies of the Stuart Bay Formation (Lower Devonian), Bathurst Island, arctic Canada
Fourteen taxa of stromatoporoids are described from allochthonous blocks of reefal limestone embedded in siltstones of late Gedinnian to Siegenian age. The fauna is a mixture of genera that characterize Ludlovian–Gedinnian rocks ( Actinodictyon, Parallelostroma, Syringostromella ) and those that cha...
