Histovariability and fossil diagenesis of Pissarrachampsa (Pseudosuchia, Notosuchia, Baurusuchidae) from the Upper Cretaceous of Southeast Brazil
Pissarrachampsa, a Cretaceous notosuchian, exhibited differential growth rates in its limb bones, with the tibia growing fastest and the fibula slowest. Histological analysis revealed fibrolamellar bone tissue and varying vascularization patterns, indicating a young adult ontogenetic stage and potential adaptations for cursorial locomotion.
