地质体中主要生物分子的研究方法及应用

现代分子生物学，生物化学及有机地球化学等领域的发展，为古生物研究者在发子水平上探索地质生物世界提供了新的概念和技术手段，本文着重讨论了可用于分子古生物学研究的生物分子，例如，维管植物的木质素等稳定生物聚合物，古生物细胞内的类脂化合物，碳水化合物，蛋白质及氨基酸和含遗传信息的核酸，分子古生物资料可用于探讨化石埋藏学，古生物分子系统学，生物演化模式与机制，分子演化速率，古生态环境再造等问题，本文较详细

Biomolecules in the Geological Record: Recovery and Applications

Ancient biomolecules recovered from fossils and sediments using organic geochemical, biochemical , and molecular biological techniques have provided insight into our understanding of geological and paleobiological events at the molecular level. This paper deals with preservation, recovery and utility of biomolecules in the geological record with emphasis on recent progress of ancient DNA research. Lignin, lipids, carbohydrates, amino acids, and nucleic acids are discussed regarding their structure and recovery techniques. Recent results using DNA sequence data in addressing paleontological questions are also reviewed.
