Station 54 Cro-Magnon – Be able to recognize the of this species When do they appear in the fossil record? How do they differ from Neandertal and other early humans? Station 55– MAMMALIA EXTERNAL FEATURES – Note the skeleton and the preserved specimen of the rat. What two characteristics can be seen that differentiate mammals from other vertebrate classes? Note the pectoral girdle. What bones make up this structure? How does the sternum differ from that of the bird? What are the five types of vertebrae seen in mammals? Station 56 CLASS: MAMMALIA INTERNAL FEATURES (PP 209 210, Figs. 8.49-8.58) – – – System Structure Function Digestive System Esophagus Stomach Intestine Liver Pancreas Spleen Excretory System Kidneys Urinary Bladder Circulatory System Atria (2) Ventricle (1) Double Circuit system (whole system) Compare to bird (Why the difference in size?)
