Raymond has a Dohrenastu? from the Madison limestone. Leiosuchus and Pampay sclymptana particularly characteristic of Cordillera, differ Oernic and Mississipie. The Dinchysus (Entelodon) skeleton is the most impressive of mammal mounts here. The head appears entirely too large for the animal. The neck vertebrae do not suggest the necessary strength to hold the head seen in the flesh illustration. A finer skull than this one is worked by Barton. Two camel skeletons on slabs on exhibition. One is very young but a few months old. Both are perfect skeletons and the older one even preserves the cartilage ribs. This year Petersen has found two other entire skeletons of these camels. The incisor teeth of Dinchysus has near grooves at their base. Petersen thinks these are due to rooting.
