Bryozoan‐Rich Carbonate Units of the Erfoud Area ( SE Morocco) Record Latest Katian to Early Hirnantian Interglacial Intervals

ABSTRACT Carbonate intervals form distinctive units distributed throughout the Upper Ordovician stratal record of the clastic‐dominated Mediterranean Province of the Gondwana platform. In southern Morocco (eastern Anti‐Atlas), bryozoan‐rich deposits comprise the mixed carbonate‐s...

Redescription of Paraconularia planicostata (Cnidaria, Medusozoa) from Mississippian (late Visean) carbonates in the Maritimes Basin, Atlantic Canada

Reflecting the long-term decline in the generic diversity of order Conulariida Miller and Gurley, 1896 following its peak during Mid–Late Ordovician times (Leme et al., 2008, fig. 1; Bernad et al., 2026, figs. 1, 2), the global fossil record of conulariid cnidarians in the Missis...

Contrasting patterns of trematode and host snail dispersal across clusters of tropical crater lakes

Abstract Background Comparing the genetic diversity and population structure of parasites and their hosts can improve understanding of their respective methods of dispersal, demographic histories, and factors driving genetic differentiation. In parasite taxa such as trematodes wh...
