PLA 071) True or False: Taphonomy is the study of the processes that affect the state of an organism’s remains from the time an organism dies until the time the fossil remains are recovered. (1point) True2) There are four principles of stratigraphy. Using information from ONLY your prelab reading, identify and define two of these principles. (2 points)a. Principle of original horizontality: Layers of rock are laid down horizontal tothe Earth’s surface. b. Principle of superposition: Older layers are laid down first and then buried by younger layers. c. Principle of cross-cutting relationships: A geological feature must exist beforeanother feature can cut across or through it. d. Principle of faunal succession: Fossils succeed each other in a reliable manner that can be identified at multiple locations.3) Match the following chronometric dating techniques with the appropriate datable material. (2 points)a. Carbon-14 : Organic materials (wood, bone, shell etc.)b. K-Ar and 40Ar/ 39Ar : K-bearing minerals (glass, clay minerals, tephra)c. Uranium Series (U-Th) : U-bearing minerals (calcium carbonates such as flowstones, corals shell and teeth)d. Thermoluminescence : Quartz, feldspars, stone tools that have been heat treated4) You find a fossil with the following characteristics: a post-orbital wall, a fused mandible, bilophodont molars and a tympanic tube. Based off of these characteristics you can determine that the fossil is most likely a(n) _________. (1 point) Old World Monkey5) You find another fossil with the following characteristics: a post-orbital wall, three premolars and lateral orbital convergence. Based off of these characteristics you can determine that the fossil is most likely a(n) ________. (1 point) Tarsier 6) True or False: Context is what paleoanthropologists use to answer the following questions: What kind of environment did the species live in? When did it exist? What kind of behavior did they have? What selective pressures were they under? 7) (1 point) True8) Match the following primates with their geographic affiliation (answers can be used morethan once): (2 points)a. Strepsirhines : Africa and Asiab. Tarsiers : Asiac. Platyrrhines : Central and South Americad. Cercopithecoids : Africa and
