Mammal bones

In this paper, I attempt to refine the predictable isotopic differences between collagen and carbonate that can be found in modem faunas from temperate and cold areas, using samples from Europe, Siberia and northwestern North America. Some of the results presented here have been published previously (Bocherens et a/. 1991a, 1991b, 1994, 1995a, 1995b, 1 6 Bocherens and Mariotti 1992 Fizet et al. 1995) but additional new data are reviewed as well in order to present a new synthesis. This should provide a framework that can be used to assess the quality of preservation of the isotopic signatures in Pleistocene mammal bones and teeth from these areas.

Although materials with an interpenetrating phase microstmcture are relatively common in nature (forexample mammals bones andtmnks and branches in plants), they are still a novelty as synthetic materials. A complete review of composite materials with interpenetrating microstmctures was published by Clarke, emphasising on materials characterisation and models for property prediction [1]. 

F) optional) Increase the range of the correlation by adding data for insects. Insects have an exoskeleton, so the leg bone circumference is just the leg circumference. True, insect legs are fleshy inside, but so are mammal bones. And as you will learn in statics, the strength of a cylindrical member depends little on the material in the center.
