Abstract
1. 1. Amino acid analyses have been made of the fossil proteins from several dinosaur and two previously studied Pleistocene bones and of peptide mixtures derived from them. 2. 2. More than 90% of the protein of the Pleistocene fossils and 30–60% of that of the dinosaurs was solubilized by heating with water at 110°C. 3. 3. For the Pleistocene gelatins from 70 to 90% of their amino acids were present as peptides, for the dinosaur gelatins the peptide content has lain between 60 and 75%. Peptides and free acids in the gelatins have been separated by Sephadex filtration. 4. 4. Most of the fossil proteins not solubilized by water could be rendered soluble by mild treatments with HCl and up to 60% of this product was in the form of peptides.
