Study of fossilized tissues
Slice of bone.
Paleohistology is the study of the microstructure of fossilized skeletal tissues , offering insights into the biology , growth patterns , and physiology of extinct organisms .
Despite the decay of organic components , the inorganic elements of bone preserve critical structures such as osteocyte lacunae , vascular canals , and collagen fibers . This highly specialized field within paleontology yields insights into the lives of extinct animals , including growth history and age at death.[ 1] [ 2] [ 3] [ 4]
