Collagen Extraction and Stable Isotope Analysis of Small Vertebrate Bones: A Comparative Approach

Bone remains of small vertebrate fossils provide valuable information for paleoenvironmental and paleoclimatic reconstructions. However, direct radiocarbon dating of small vertebrates remains challenging as the extraction of sufficient good quality collagen is required. The efficiency of eight collagen extraction protocols was tested on seven samples, representative of different ages and burial environments, including both macro and small...
