Building skills: Using seeds and shells to learn about Alberta’s ancient environments

How do we know about past environments?

Historic and precontact archaeological and palaeoenvironmental sites from across Alberta tell us much about people and past environments. But how can we learn the details about that environment? This blog post will tell you how we use environmental indicators, especially macrofossils, to reconstruct what conditions were like at sites in the past.

It may seem reasonable to assume that the environment when an archaeological site was inhabited by people was generally the same as it is now, and this is sometimes the case. However, the archaeological record in Alberta goes back at least 13,000 years , to the end of the last major glaciation and its transition to our present epoch (the Holocene).
