Rugose corals Polycoelaceae and Tachylasmatina subord. n. from Dalnia in the Holy Cross Mts

Abstract

Fourteen new species of tetracorals have been described from the neptunian dykes on Dalnia Hill (Wocklumeria or Gattendorfia Stage) in the Holy Cross Mts, and assigned to nine genera (three new ones) and four families (one new family and one new subfamily). Corals with the pentaphylloid type of septal insertion have been separated to form a new suborder Tachylasmatina, their separation from the superfamily Polycoelaceae being based on their different ontogeny.
