Taphonomic signatures and degree teeth wear.

A: degree of articulation; 4 = skull and lower jaw articulated with the vertebrae; 3 = skull articulated with the lower jaw, 2 = dentary articulated with the other bones of the lower jaw (articular complex); 1 = isolated dentary; B1: degree of fragmentation with the presence of fragments in the sample (only for dentary), zero is equal to absence of fragmentation, the numbers 1 to 5 represent the total of fragments, but when the size of the fragment is very small it is counted as 0.5; B2: fragmentation degree, in the absence of fragments in the sample (only for dentary), the number represents the total of fractures that represent absent fragments, but when the size of the fragment is very small it is counted as 0.5; E: level of fractures: 0 = absent; 0.5 = one weak fracture; 1 = when fractures are very weak and few; 1.5 = when fractures are very weak and few, and one fracture is stronger; 2 = when fractures are weak (more than five, and get counting) or/and few stronger fractures; 2.5 = when fractures are weak (more than five, and get counting) or/and few stronger fractures (no more than five); 3 = when fractures are strong and more than 5, and/or many weak fractures; 4 = many and stronger fractures. These observations were made with stereoscopic microscope. Teeth wear in occlusal surface, is from 0 to 3; where 0 means no worn and 3, very worn.
