Fill in the Blanks Compare the following mammal skulls and decide whether their teeth shapes are generally sharp, flat, or intermediate. Bobcat: Fox:Pig:Sheep:   Fill in the Blanks Based on their teeth shape and dental formulas, state whether each of these mammals are herbivores, carnivores, or omnivores. Bobcat:Fox:Pig:Sheep: Review the forelimb skeletal anatomy figure in your reading exercise (Figure 8.4). Look at the types of bones and the number of bones found in each tetrapod forelimb. Limbs with digits are homologous for tetrapods. Create a hypothesis explaining what bones the common ancestor of tetrapods probably possessed. Based on similarities among forelimbs, what bones did the common ancestor of tetrapods probably possess? In your answer, refer to the bones and how they are connected to each other.

Rodentia skull and dentition characteristics: For each Order of Mammalia in this lab, describe the skull characteristics. Be sure to note if incisors (upper/lower), canines, premolars and molars are present. Also note special features of molar teeth in the bobcat and the mule deer. If it’s easier to instead do this on the field guide with an annotated picture of each skull type, that works too – just note that here.
