The palaeobiogeography of South American gomphotheres
Journal of Palaeogeography, 2013 Gomphotheriid proboscideans reached South America as Late Cenozoic immigrants from North America. However, disagreements over alpha taxonomy, age dating and phylogenetic relationships have produced three competing hypotheses about this immigration: (1) a

Palaeobiology and evolutionary context of Angulithes mermeti, a streamlined early Late Cretaceous shallow-water nautiloid [PDF]
Acta Palaeontologica Polonica, 2019 Cretaceous nautiloids are commonly characterized by inflated shells and prolonged stratigraphic ranges. In the Albian, the species of Angulithes appeared and compressed, short-lived forms with narrow venters emerged during the Cenomanian age.
