Bone Histology Linking The Past To The Present: New Discoveries About Caimans’ Evolutionary History In South America

Bone histology is, comparatively, a modern branch in paleontology. The techniques slowly started to be applied during the 1960s and 1970s on fossilized bones (Figure 1). But It was during the 80s and 90s that paleohistology became bigger and helped to shed light on some questions about vertebrate’s biology and evolution. Since then, over the past forty years, it is considered a reliable proxy in science providing answers that gross macro morphology cannot. Figure 1. The...

Hidden Secrets In The Fossilized Bones Of A Cretaceous Crocodyliform From Brazil

The study of bone microanatomy provides complementary knowledge which is unavailable in most of the morphological analysis of fossil vertebrates. New information about growth, metabolic rates, and lifestyle pop up after analyzing thin sections of tetrapod bones under microscopy. Moreover, bone histology can also detect features that indicate degrees of bone specializations, such as osteosclerosis. It means that there is an increase in the inner bone compactness which can be related to semiaquatic reptiles and has been already found in...
