Coordinated shifts to non-planktotrophic development in spatangoid echinoids during the Late Cretaceous.

Despite widespread interest in the interplay between evolutionary and developmental processes, we still know relatively little about the evolutionary history of larval development. Many clades exhibit multiple shifts from planktotrophic (feeding) to non-planktotrophic (non-feeding) larval development. An important question is whether these switches are scattered randomly through geological hist...

Late Cretaceous Echinoids from the Seymareh member (Lopha Limestone member), KabirKuh Anticline, Southwest of Iran

In the present study, Kabir kuh Section, related to the Seymareh or Lopha Limestone member (Gurpi Formation) have been Selected. The member has yielded a rich echinoid fauna and 21 species of Echinoid belonging to 14 genera are recognized and described. The Kabir Kuh section yielded two regular echinoid taxa: Salenia nutrix and Goniopygus superbus, one holectypoid taxa: Coptodiscus noemiae, two...

Morphological and systematic interpretation of some Late Cretaceous (Turonian-Santonian) irregular echinoids, Kopet-Dagh Basin, NE Iran

Abderaz Formation is one of the Upper Cretaceous formations in the Kopet-Dagh sedimentary basin. A stratigraphic section from the mentioned formation is selected for detailed systematic description with regard to echinoids. Numerous well preserved representatives of the families Mircrasteridae wright, 1857 and Echinocorythidae Lambert, 1920 are described from the Ghaleh-Zoo stratigraphic sectio...

Assessing the robustness of disparity estimates: the impact of morphometric scheme, temporal scale, and taxonomic level in spatangoid echinoids

– The joint quantification of disparity and diversity is an important aspect of recent macroevolutionary studies, and is usually motivated by theoretical considerations on the pace of innovation and the filling of morphospace. In practice, varying protocols of data collection and analysis have rendered comparisons among studies difficult. The basic question remains, how sensitive is any given d...

Tectonical history of Arabian platform during Late Cretaceous An example from Kurdistan region, NE Iraq

New simplified tectonic models and depositional history of Late Cretaceous rocks are established in a part of Zagros Orogenic Belt that is located in the Northeastern Iraq. These rocks constutes the most important Cretaceous oil reservoir in the Middle East. The dependent tools are petrography, field study and the concept of drowning phases. This concept is relatively new and accurate in explan...
