What Is Archaeology? Flashcards
Archaeology
Study of cultures of the past through material remains (artifacts, ecofacts, and features). The goal is the preserve the artifacts, conserve the site, and explain cultural changes
Culture
The social structure created and learned by humans. It consists of burial customs, languages, gender roles, social stratification, oral traditions, human behavior and outcomes, etc.
Diffusion
Transfer of ideas, ideologies, and practices by word of our of example
Invention
Creation of something new or improvement upon an older technology
Migration
Movement of people as a peaceful choice or as the result of a stimuli.
Artifacts
Man made material goods (ex. stone tools, cups, jewelry, pottery, cave paintings)
Ecofacts
Objects from nature that are not modified but are placed in a particular manner (ex. seeds, animal bones)
Features
Man made, nonportable artifacts (ex. burial sites, homes)
Prehistory
History before civilizations became literate. The focus of the study of the past is on human origins
World history
Prehistory with a global perspective (ex. how agriculture was developed independently in many regions of the world)
Grotte de Chauvet
One of the earliest painted caves from the ice age that was painted repeatedly over the years. Images of animals and lifestyle from during the ice age.
Tollund Man
Found preserved in a bog so a lot of information about him could be learned
Otzi
Found preserved by ice in the mountains. He was a hunter (carried bags made of hide and hunting tools), had ritualistic tattoos, had the spearhead that caused his death lodged in his shoulder, and had the blood of 4 different people on him.
Context
Position of an object in time and space. Gives relationship to other artifacts, use of object, and site formation process. Factors to consider are the matrix, provenience, and association
Excavations
Digging to expose what is underground, recording and analyzing artifacts
Scientific Method
Excavations are destructive so a precise plan is necessary before digging. Need hypothesis, initial survey, data collection, and conclusions/publishing results
Hypothesis
Preparing questions about goals based on initial research. How did the people live? Why did their lifestyles change? How did societies develop or collapse?
Data Collection
Looking through previous documents, history and excavation data
Conclusions
Support hypothesis with results and ask further questions. Public results to create a permanent record of data
Dating Methods
Relative and absolute ways to place recovered artifacts in a time frame
Carbon 14
Getting half life from organic objects. Though on a large scale, good for determination of time period, there is a significant margin of error on the smaller time scale
Thermal Luminescence
Used for objects that were exposed to fire. Crystals accumulate electrons at known rate. Heating liberates electrons and creates light. Measuring the light can determine when the crystal was last exposed to heat
Writing
Analyzing written documents
Dendrochronology
Counting tree rings and comparing ring patterns because the ring states vary based on environmental conditions
Potassium Argon Dating
Used to date volcanic ash. Doesn’t use the actual artifacts so their dating is done using the law of association
Stratigraphy
Layers of soil and rocks
