RADIOACTIVE DECAY __ the regular process by which
radioactive isotopes break down into their decay products with a half-life which
is specific to the isotope in question.

RAISED BEACHES __ These are
remnants of former coastlines, usually the result of processes such as isostatic
uplift or tectonic movements.
RAMADA __ An open-air shade built of upright posts that are covered
with a flat roof. The Pimas and Papagos also made use of the ramada as a
focal point of family activity.
RAMON TREE __ A nut-bearing tree common in the lowland rain forests of
the Yucatan Peninsula.
RANCHERIA __ A form of village arrangement in
which individual dwellings are widely separated. This can be contrasted with the
Pueblo sale of architecture in which dwellings within a village are attached to
one another in an apartment-like complex.
RANKED SOCIETIES __ Societies in
which there is unequal access to prestige and status e.g. chiefdoms and states.
RATIONAL ECONOMIC DECISIONS __ The weighing of available alternatives and
calculation of which will provide the most benefit at the least cost.

extent of individual communities.
REBELLION __ An attempt within a society to disrupt the status quo
and redistribute the power and resources.

RECLAMATION __ Activities that move objects from archaeological
context back into systemic context.
RECORDING UNIT __ A level,
feature, or occupation surface used as a reference point to designate the
recovery location (provenience) of artifacts at a site.
RECOVERY THEORY __ The
principles on which are based the choice of techniques to be used in a given
archaeological survey and excavation.
RECOVERY UNITS __ The two-dimensional
(in surface collection) and three-dimensional (in excavation) spaces in which
archaeological materials are recovered and recorded at a site.
REFITTING __ Sometimes referred to as conjoining, this entails attempting to put
stone tools and flakes back together again, and provides important information
on the processes involved in the knapper's craft.
REFUGIUM __ A geographical area which remains unaltered or changes
much more slightly than surrounding regions in response to a change in
climate. A refugium therefore constitutes a haven for plants and animals
which were once more widely distributed (plural refugia).
REFUTATIONIST VIEW __ Approach which holds that science consists of theories
about the empirical world, that its goal is to develop better theories, which is
achieved by finding mistakes in existing theories, so that it is crucial that
theories be falsifiable (vulnerable to error and open to testing). The approach,
developed by Karl Popper, emphasizes the important of testability as a component
of scientific theories.
REGIONAL DIMENSION __ The artifacts that occur in close association
with each other.
REGIONAL SURVEY __ Locating and describing the
remains of settlements in a region.
REGIONAL SYSTEM __ The behavioral
component made up of communities related to each other by trade, political
alliances, and other forms of social interaction.
RELATIVE DATING __ Dating of
an event or process according to its chronological position (earlier or later
than) relative to another event or process.

cultural system can be viewed only in terms of the principles, background, frame
of reference, and history that characterize it.
RELIEF __ A form of sculpture
where the figures stand out from, but are still attached to the background.
RELIGION __ A framework of beliefs relating to supernatural or superhuman beings
or forces that transcend the everyday material world.
REMOTE SENSING __ Observation and recording at a distance, especially
by specialized serial photography of sites and natural environment.
REPLICA __ A copy or reproduction of the original.
RESCUE ARCHAEOLOGY __ A
term applied to the emergency salvage of sites in immediate danger of
destruction by major land modification projects such as reservoir construction.
RESEARCH DESIGN __ The plan for an archaeological investigation.
MOBILITY __ The degree of movement of household social units from dwelling to
dwelling, particularly of hunting-gathering communities
RESISTIVITY __ A
pre-excavation method for determining the size, shape and occasionally the
nature of an archaeological site. It works on the principle that different
deposits offer differential resistance to an alternating current passing through
them, largely in response to the amount of water contained within them. Thus a
damp, buried ditch will provide less resistance while a wall or foundation ill
offer more. Mapping electrical resistance across a site can greatly aid the
archaeologist in deciding where to dig.
RESHARPENING FLAKES __ Usually small
flakes removed from the edges of chipped-stone cutting or scraping tools to
rejuvenate the effectiveness of the edge.
RESTORATION __ The process of cleaning and studying an artifact and
attempting to return it to its original form (before it was buried).
RETICULE __ A frame with a grid used as an aid in mapping. Those used in
Manitoba consist of a square wooden frame with a network of strings set at
regular intervals. These may be placed over a feature thus allowing more
accurate sketch maps to be made. Locally, reticules have found their greatest
utility in the recording of petroforms.
RETOUCHER __ A small tool (such as
that found on the body of Otzi the Iceman) made especially for pressure flaking
flint and chert tools. In the iceman's case, his retoucher was at first mistaken
for the stub of a pencil.
REVERSE __ "Tail" side of a coin.
STRATIFICATION __ Earlier materials overlying later materials.
An attempt to overthrow the existing form of political organization, the
principles of economic production and distribution, and the allocation of social
REWORKING __ Modification of an object so that it may be used again.
The reworking of stone artifacts after breakage was particularly common
in times and places where suitable lithic resources were scarce. A
projectile point which had been broken at the time could easily be
re-sharpened and some were probably reworked several times in this
fashion, becoming shorter relative to their widths each time. Drills and
side-notched end-scrapers with bases similar to those of the projectile
points with which they are associated are often considered to be
examples of reworking.
RHYOLITE __ A fine-grained igneous rock of the
same composition as granite (quartz, feldspar and mica), but capable of being
worked by flaking into tools. Characteristically, rhyolite has a glossy
appearance and small inclusions of quartz and feldspar within the finer matrix.
RIMSHERD __ A fragment of pottery which originally formed part of the rim of a
RIPARIAN __ Pertaining to the bank of a river.
RITE OF SOLIDARITY __

ROCK SHELTER __ A small
cave or overhang of rock which afforded some degree of protection from the
elements either as a permanent camp or temporary location of activity.
STAMPING __ A pottery design produced by rocking a straight or notched edge from
one end to the other, while moving the tool sideways across the surface of the
wet clay. The result is a zigzag pattern of curved lines.
ROLE __ A set of
behavioral expectations appropriate to an individual's social position.
ROMAN COLOSSEUM __ Built in Rome, Italy between A.D. 70 and 80, the four-story
structure was the site of bloody fights between animals, gladiators, or animals
versus gladiators for more than 300 years. After A.D. 404, the gladiator battles
ended, but scuffles between animals in front of about 50,000 spectators remained
a popular sport until the 6th century A.D.
ROMAN COPIES OF GREEK ORIGINALS __ Replicas of famous Greek statues
made for the Roman market.

Etruscan kings till the establishment of the empire by Augustus Caesar.
ROOF COMB __ The part of a Mesoamerican temple that extends over the
usable area. Frequently carved with glyphs and figures.
ROSETTA STONE __ A basalt slab discovered at Rosetta (Rashid), at the

now in the British Museum. The text is an honorific decree of Ptolemy V
(196 B.C.) that was written in ancient Greek, hieroglyphics, and
demotic, which is a later form of ancient Egyptian. The stone enabled
the French explorer and linguist Champollion to decipher ancient
Egyptian hieroglyphics by comparing the unknown text of hieroglyphics to
the known and translated text in Greek and demotic.
ROV __ Remote Operated Vehicles are remote controlled underwater
robots used instead of divers for difficult operations, e.g. on great
