Palaeobiology and osteohistology of South African sauropodomorph dinosaurs

Journal of Anatomy, EarlyView.
We found that the transitionary Sauropodiformes show both the traits of rapid growth of derived Sauropoda as well as interrupted growth of early branching Sauropodomorpha. There appears to be much more variation in growth dynamics of Sauropodiformes than initially thought.

Evolution of growth strategy in alligators and caimans informed by osteohistology of the late Eocene early‐diverging alligatoroid crocodylian Diplocynodon hantoniensis

Journal of Anatomy, EarlyView.
Living alligatoroids (alligators and caimans) share osteohistological features and display similar overall growth rates. However, it is unclear if these shared patterns are the result of convergent responses or reflect an ancestral condition. In this study, we histologically sampled nine femora of the fossil alligatoroid Diplocynodon hantoniensis to ...
