Terrestrial crustacean breeding trace fossils from the Cretaceous of Patagonia (Argentina): Palaeobiological and evolutionary significance
(Elsevier Science, 2008-07)
The breeding trace fossils described herein along with the high density of Loloichnus baqueroensis in the Cretaceous formations of Patagonia suggest that crayfishes were soil engineers along the Cretaceous in southern South ...
Novel data on aetosaur (Archosauria, Pseudosuchia) osteoderm microanatomy and histology: palaeobiological implications
(Wiley Blackwell Publishing, Inc, 2018-09)
One of the most striking features of aetosaurs is the possession of an extensive bony armour composed of dorsal, ventral and appendicular osteoderms. With the purpose of establishing the main histological changes during ...

Fractal dimension and cheek teeth crown complexity in the giant rodent Eumegamys paranensis
(Wiley, 2013-04)
In this work, we analyse cheek teeth crown complexity through the calculation of fractal dimension in the giant caviomorph rodent Eumegamys paranensis (Late Miocene of Argentina) and evaluate its functional significance. ...
Anatomy, phylogeny and palaeobilogy of Early Archosaurs and their kin
(Geological Society, 2013)
Archosauria include two extant clades, crocodylians and avians. However, the diversification of the avian and crocodylian crown groups are relatively recent events that began during the Late Cretaceous (Brochu 2001, 2003; ...
