The Cretaceous corals from the Bisbee Group (Sonora; Late Barremian - Early Albian): Solenocoeniidae

Resumen

The current work constitutes the third part of the systematic revision about the corals from the Bisbee Group (Late Barremian to Early Albian) and deals with the Solenocoeniidae. This family taxon is applied instead of the poorly defined Cyathophoridae. The family has three genera in the Cretaceous of Sonora: Confusaforma, Cryptocoenia, and Cyathophoropsis. To distinguish samples within the Sonoran fauna and species of this genus, systematic measurements of the corals were taken and statistically analysed. From the Bisbee Group, two Confusaforma, six Cryptocoenia, and one Cyathophoropsis species are here described and illustrated. Most are common Early Cretaceous species with a wide geographic and stratigraphic distribution
