Chemical Composition of Bone Remains of Hadrosaurs in the Amur Region

摘要

The Mesozoic landscape of America, Africa, and Eurasia was dominated by hadrosaurs, trochodonts of the ornithichian order (Hadrosauridae family). Hadrosaurs were the largest biped dinosaurs with some species exceeding 15 m in length. Most researchers believe that rock sequences with hadrosaur bone remains have an Upper Cretaceous age [1]. Natural complexes are undergoing alterations under the influence of the industrial activity of mankind in the present-day epoch of technogenesis. Moreover, the anthropogenic impact on landscape is comparable to (or even stronger in some cases) that of natural forces, resulting in alterations of the chemical composition of both separate elements of the landscape and the whole landscape [2]. The aim of the present work was to study the chemical composition of bone tissues of the dominant living being in the landscape of the upper and middle Amur region during the Mesozoic Era (hydrosaur bone remains) and present-day epoch of technogenesis (human bones).
