Claire Bazemore U1408482 ANTH 1020 Fossil lab activity 1. Name three specimens identified as Australopithecus . Using the 3D/2D feature, describe how they are similar and how they are different. Speculate about why there might be differences. There is the australopithecus afarensis cranium, and two australopithecus africanus craniums. Between the three specimens, the australopithecus afarensis cranium was the oldest. The australopithecus afarensis skull was found at the same area as Lucy’s skeleton but it is much bigger than the skull of Lucy and of other females that are in that species. The australopithecus africanus cranium is from a nearly complete adult and this fossil's face is “strongly prognathic”. At first they thought that this skull was from a female but it is now thought to be from a male. 2. Name three specimens identified as Neanderthal. Using the 3D/2D feature describes how they are similar and how they are different. Speculate about why there might be differences. There are the homo neanderthalensis craniums and homo neanderthalensis mandibles. One of the neanderthalensis craniums I looked at had its age marked as “age uncertain” because it was found in 1829, which was before Charles Darwin published “on the origin of species”. Another cranium that was found, and is also one of the most important individuals that was found at La Ferrassie is known as La Ferrassie 1. This skull is from a male and is the largest and most complete neanderthal skull found. The

homo neanderthalensis mandible is around 70,000-50,000 years old and was found at the la ferrassie site in 1909.
