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]
