  • Discovery of several new specimens of the gigantic Eocene ground bird Diatryma gigantea from the Willwood Formation of northwestern Wyoming, has prompted an analysis of its feeding apparatus and an assessment of the mode of life of this unusual bird. Diatryma exhibits many of the features predicted by biomechanical models to occur in animals delivering large dorsoventral bite forces. Similarly, the mandible of Diatryma, which was modeled as a curved beam, appears well equipped to withstand such… CONTINUE READING
