Radiocarbon dating of bone collagen routinely focuses on the extraction of bulk proteins that are then purified before radiocarbon measurement.However, the extracted bulk gelatin can be heterogeneous and include, or be cross-linked to, potential contaminants from the depositional environment, such as humic and fulvic acids, rootlets, cellulose, sediments, and other plant and animal remains including amino acids from bacteria and microorganisms (1, 2).The process for determining the child support amount when there are step-parents is not set out clearly in federal, provincial or territorial legislation.

This rules out carbon dating for most aquatic organisms, because they often obtain at least some of their carbon from dissolved carbonate rock.

Spousal and family relationships of varying permanence, and blended families, have become more common in Canadian society in recent years.

A person who acts as a parent to the children of his or her spouse may have a legal obligation to support those step-children after the relationship with the spouse ends.

This method is applied to two important sites in Russia and allows us to report the earliest direct ages for the presence of anatomically modern humans on the Russian Plain.

These dates contribute considerably to our understanding of the emergence of the Mid-Upper Paleolithic and the complex suite of burial behaviors that begin to appear during this period.

These inaccuracies in turn frustrate the development of archaeological chronologies and, in the Paleolithic, blur the dating of such key events as the dispersal of anatomically modern humans.

Here we describe a method to date hydroxyproline found in collagen (∼10% of collagen carbon) as a bone-specific biomarker that removes impurities, thereby improving dating accuracy and confidence.
