Buckman’s Rules of Covariationtion suggests that shell morphogenesis may not be random but constrained either by adaptive constraints or simple constructional scaling rules. The cause(s) remain debated. Hence, although Buckman’s rules of covariation are now widely documented and acknowledged, several aspects of their scope and limits still remain to be investigated.

Paleobiogeography of Early Cretaceous Ammonoidsthe Albian stage, displays a more distinctive differentiation between Boreal and Tethyan faunas. The late Barremian marks the onset of the Austral Realm, originating from faunas that originally evolved in the Indo-Pacific Subrealm of the Tethyan Realm.

Biostratigraphy of Triassic Ammonoidsrest in Triassic ammonoid biozonation has occurred during the last few decades, leading to the recognition of tens of ammonoid zones spanning about 50.9 Myr (leading to an average duration for ammonoid biochronozones of about 0.74 Myr), whose correlation and definition are herein synthesized.
