Fossildiagenesis and ontogenetic insights of crocodyliform bones from the Adamantina Formation, Bauru Basin, Brazil

The histological analysis of fossil bones allows a taphonomic approach, especially to fossildiagenesis. We studied the femur, vertebra, and osteoderm of the crocodyliform Montealtosuchus arrudacamposi (Adamantina Formation; Late Cretaceous), to make inferences of the sequence of the diagenetic processes. Cross-sections of the bones and the rock matrix that fills the medullar cavity were analyzed under a scanning electron microscopy with...
