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

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. Lagomorpha skull and dentition characteristics

Fill in the the table to describe the Ribs, Sternum and Appendicular Structures (1-3 sentences)

Select all of the traits provided below that appear in this specimen - low forehead - vertical forehead - sagittal keeling - sagittal crest - broad cranial base (smaller cranial capacity) - large canines

From the following 5 characters, characterise at least 2 key features of the dinosaur teeth provided and use it to determine whether each dinosaur is a carnivore or a herbivore. Write the supporting characteristics out in full but also give the associated character number and its state e.g., denticles absent, 4(0). 1. Tooth shape: (0) Cylindrical [inconclusive] (1) Conical [carnivore] (2) Low and broad [herbivore] 2. Tooth curvature: (0) Straight [inconclusive] (1) Recurved [carnivore] 3. Tooth top: (0) Flat [herbivore] (1) Single sharp cusp [carnivore] (2) Multiple sharp cusp [herbivore] (3) Single rounded cusp [inconclusive] 4. Denticles (serrations): (0) Absent [inconclusive] (1) 'Coarse', few in number and very large [herbivore] (2) 'Fine', many and relatively small [carnivore] 5. Constriction between top and base of tooth (0) Absent or weak. Constriction occupies >85% of largest width [inconclusive] (1) Well-developed. Construction occupying <85% of largest width [herbivore]…

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.

From the following 5 characters, characterise at least 2 key features of the 3 dinosaur teeth provided and use it to determine whether each dinosaur is a carnivore or a herbivore. Write the supporting characteristics out in full but also give the associated character number and its state e.g., denticles absent, 4(0).

Compare the forelimb anatomy of the ancestor (left) to the anatomy of other vertebrate relatives Abbreviate your answers using the first letter of the bone or bone group in the following way: H for humerus, R for radius, U for ulna, C for carpals, M for metacarpals, and P for phalanges.  Animal Bones resembling common ancestor Bones that differ from common ancestor Turtle         Human         Horse       Bird         Bat         Seal

Rodentia skull and dentition characteristics: For each Order of Mammalia in this lab, describe the skull characteristics.
