Description

This article is the first in the Alberta Lithic Reference Project series, the goal of which is to assist the identification of raw materials used for pre-contact stone tools in the province. Each article will focus on one raw material; the current article discusses a partially fused, glassy, vesicular rock that originates in Northwest Territories called Tertiary Hills Clinker (THC). THC appears in archaeological sites in northern and central Alberta. A suite of techniques indicates that it can be geochemically sourced much like obsidian. The accurate identification of THC can reveal significant relationships between occupants of Alberta and the Mackenzie Basin to the north.

Description

The focus of this manual is the accurate determination of the age of fish species which are found in Alberta. The manual consists of three parts. The first part deals with general issues pertaining to ageing fish, such as standardization data reporting, the use of data in mathematical models to characterize growth of fish from different populations, general approaches to ageing fish, and a consideration of criteria for the validation of an ageing technique. The second part consists of a discussion of ageing techniques for individual species. The third part is a general account of the use of different structures for ageing fish.
