How are Macrobotanical remains preserved?
Table of Contents
The most basic manner to recover botanical remains is to use bucket flotation. Here the soil is placed in a bucket, water is added, contents are swirled around, and then carefully poured into a sieve. This sieve will catch the lighter particles, while the heavier plant remains will stay in the bucket.
What is Macrobotanical remains in archaeology?
Plant remains recovered from archaeological contexts that can be seen with the naked eye. These tend to be seeds and wood fragments, but nuts and other fruits may also be represented. From: macrobotanical remains in The Concise Oxford Dictionary of Archaeology ยป
How do archaeologists collect plant remains?
Before flotation, most evidence of small and fragile plant remains was tossed away! Flotation uses water and some sort of agitation to break away soil from other materials, like plants. If the plant remains are carbonized, they will float to the surface and archaeologists can collect them in a fine mesh sieve.
Which of the following is an example of a Macrobotanical remain?
Macrobotanical remains can be seen by the naked eye or low power microscope. Examples of these include seeds and charcoal. Microbotanical remains are so small that in order to view them, you need to use a high-power microscope. These include pollen, starch grain, and phytoliths.
Which type of method is used by Paleobotanists to recover small plant seeds from archaeological excavations?
flotation
With the rise of Processual archaeology, the field of Paleoethnobotany began to grow significantly. The implementation in the 1970s of a new recovery method, called flotation, allowed archaeologists to begin systematically searching for plant macrofossils at every type of archaeological site.
What is petrography archaeology?
Petrography is deals with the source, occurrence, structure and history of rocks and includes chemical and optical characterizations.
What can Macrobotanical remains tell us?
The term macrobotanical is used to discuss those plant remains that we can see with the naked eye. Identification of the recovered seeds, nuts, bones, plant parts, etc., provides direct information on what resources were available in the site vicinity, and also those definitely collected by the people who camped there.
How are archaeological plant remains typically preserved?
Flotation is the most common processing technique employed for the recovery of carbonized plant remains. It uses water as a mechanism for separating charred and organic material from the sediment matrix, by capitalizing on their buoyancy properties.
What are Microbotanical remains?
Microbotanical remains include spores, pollen, phytoliths, starch grains, and similar materials produced by fungi and plants. Their study provides insights into aspects of environments and cultures otherwise unavailable in the archaeological record and elaborates upon others.
What are faunal remains?
Faunal remains are the items left behind when an animal dies. These include bones, shells, hair, chitin, scales, hides, proteins and DNA. Of these items, bones and shells are the ones that occur most frequently at archaeological sites where faunal remains can be found.
What is ceramic provenance?
Ceramic petrography (or ceramic petrology) is a laboratory-based scientific archaeological technique that examines the mineralogical and microstructural composition of ceramics and other inorganic materials under the polarised light microscope in order to interpret aspects of the provenance and technology of artefacts.
