Date Time Researchers find biogeographical affinity in Cretaceous flora from two islands of old Tethys Ocean Scanning electronic microscope images of gyrogonites of the new species Mesochara dobrogeica (above) and the utricles of the new Clavator ampullaceus var. atibracteatus variety (below) found in the region of Dobrogea (Romania). Palaeographic map of Tethys Ocean during Lower Cretaceous (Berriasian, 140 million years) with the distribution of some species of charophytes found for the first time in the paleo-island of Hateg (Romania). A study published in Cretaceous Research expands the paleontological richness of continental fossils of the Lower Cretaceous with the discovery of a new water plant (charophytes), the species Mesochara dobrogeica. The study also identifies a new variety of carophytes from the Clavator genus (in particular, Clavator ampullaceus var. latibracteatus) and reveals a set of paleobiographical data from the Cretaceous much richer than other continental records such as dinosaurs’.
