Why are paleontologists excited to find teeth in the fossil record? Name three pieces of information paleontologists can learn from fossil teeth.

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).

Why was the evolution of jaws selected for? (Choose All That Apply) There's more than one correct answer. Please highlight the correct answer    it allowed for the evolution of teeth it increased the efficiency of feeding it increased respiratory efficiency it increased the ability to grab food

Over a period of millions of years, cheetahs evolved to become faster and faster (as did their prey). Give a Lamarckian explanation of how cheetahs evolved to became faster. Then explain why this explanation is not scientifically possible.

What do fossils suggest about Australopithecine diet and how it may have varied between the two groups? Explain your answer and be explicit as to what traits support your answer.
