Definition: Palaeodendrology is a branch of paleontology that focuses on the fossil record and the relationships between fossils found in different geological periods. It aims to understand how ancient organisms lived, what they ate, and where they came from, as well as how their remains were preserved over time. Palaeodendrologists study the remains of extinct species, including plants, animals, and humans, and try to reconstruct the evolutionary history of these groups, especially in the context of their environment
