Comparing apples and oranges: Why infant bone collagen may not reflect dietary intake in the same way as dentine collagen.

ABSTRACT:

Objectives

Recent developments in incremental dentine analysis allowing increased temporal resolution for tissues formed during the first 1,000 days of life have cast doubt on the veracity of weaning studies using bone collagen carbon (δ¹³ C) and nitrogen (δ¹⁵ N) isotope ratio data from infants. Here, we compare published bone data from the well-preserved Anglo-Saxon site of Raunds Furnells, England, with co-forming dentine from the same individuals, and investigate the relationship of these with juvenile stature. The high-resolution isotope data recorded in dentine allow us to investigate the relationship of diet with juvenile stature during this critical period of life.

Materials and methods

We compare incremental dentine collagen δ¹³ C and
