Investigations at Research Neutron Source lead to discovery of a previously unknown animal species. Dr. Michael Schulz at the neutron radiography facility ANTARES. A long snout, a massive jaw and sharp teeth - these are some features of the newly discovered species Tessellatia bonapartei. It belongs to the group of Cynodontia (which literally translates to "dog teeth"), mammal-like animals from which mammals eventually evolved. Argentinian researchers found the bones of the roughly mouse-sized cynodont species in the desert-like Talampaya National Park in the west of Argentina. "The bones were very fragile and therefore it was not possible to remove the surrounding rock without risking to damage them", explains Dr. Aureliano Tartaglione of the research neutron source Heinz Maier-Leibnitz at TUM. He worked on the project with Dr. Leandro Gaetano from CONICET (National Scientific and Technical Research Council in Argentina).
