Notoungulate faunas of north-western Argentina: new findings of early-diverging forms from the Eocene Geste Formation
New material is described that includes Notoungulata of generalized morphology, two morphotypes of basal typotherians, and two interatheriid taxa (including Antofagastia turneri gen. et sp. nov.) that increase the variety of groups and provide new information about previously known taxa for this unit.
Cladistic Analysis of Iguania and a Fossil Lizard from the Late Pliocene of Northwestern Argentina
The phylogenetic analysis of 396 morphological characters indicates a sister-group relationship between the new taxon and a clade formed by the families Liolaemidae, Leiocephalidae, and Tropiduridae, and the monophyletic status of Iguanoidea and other groups within Iguania that are named and diagnosed are supported.
A New Eocene Toxodontia (Mammalia, Notoungulata) from Northwestern Argentina
A cladistic analysis supports the paraphyly of Notohippidae proposed by previous authors and validates the monophyly of the genus Pampahippus, which ranks as a relatively basal taxon within Toxodontia.
Ecomorphology of Mammalian Fossil Lineages: Identifying Morphotypes in a Case Study of Endemic South American Ungulates
This work explored the patterns in morphospace of representatives of all notoungulate families on the basis of the qualitative scoring of 31 cranial characters that provided a basic description of shape and an approximation to sensory and mechanical functions of the skull.
Phylogenetic relationships and palaeobiology of a new xenungulate (Mammalia: Eutheria) from the Palaeogene of Argentina
Xenungulates are a peculiar group of bilophodont ungulates, widespread over South America during the Paleocene and early Eocene. Here we describe, illustrate and analyse a new Xenungulata, Rodcania
Anatomical and Systematic Study of Proximal Tarsals of Ungulates from the Geste Formation (Northwestern Argentina)
Abstract. Over the last decades, Paleogene outcrops in northwestern Argentina have been yielding abundant information about the evolution of South American mammals during the early Cenozoic. This
Biotransformation of water lettuce (Pistia stratiotes) to biohydrogen by Rhodopseudomonas palustris
Aim of the paper was to assess the feasibility of producing hydrogen as a biofuel by photofermentation of fermented water lettuce (Pistia stratiotes L.) waste biomass, after a nitrogen‐stripping
A New Sebecid Mesoeucrocodylian from the Paleocene of Northwestern Argentina
ABSTRACT A new crocodyliform, Sebecus ayrampu, sp. nov., is described based on the rostral region of the skull, mandibular rami, and a distal portion of the femur collected in Paleocene rocks of
