First report of Hadrosia Cooper, 1983 in South America and its biostratigraphical and palaeobiogeographical implications
چکیده انگلیسی

A new terebratulid species, Hadrosia gracilis, from the Lower Cretaceous Rosablanca Formation in Central Colombia is described. The new method of three-dimensional reconstructions of the internal morphology of this taxon results in the subjective synonymization of the Nerthebrochinae in favour of the Sellithyridinae. The geographical distribution of species of Hadrosia in South America and Western Europe is a further argument for a direct pathway between these two regions during Early Cretaceous time.


► A new terebratulid species, Hadrosia gracilis, is described based on 3D reconstructions after serial sections.
► This work included a subjective synonymization of the Nerthebrochinae in favor of the Sellithyridinae.
► We propose a direct pathway between northern South America and Western Europe during Early Cretaceous time.
