We describe two new cynodonts from the early Late Triassic of southern Brazil. One taxon, Bonacynodon schultzi gen. et sp. nov., comes from the lower Carnian Dinodontosaurus AZ, being correlated with the faunal association at the upper half of the lower member of the Chañares Formation (Ischigualasto-Villa Unión Basin, Argentina). Phylogenetically, Bonacynodon is a closer relative to Probainognathus jenseni than to any other probainognathian, bearing conspicuous canines with a denticulate… 

A New Prozostrodontian Cynodont (Eucynodontia, Probainognathia) from the Upper Triassic of Southern Brazil

ABSTRACT Probainognathian cynodonts are well represented in the fossil record from the Middle and Upper Triassic of South America, especially in Brazil and Argentina. In this contribution, we

The African cynodont Aleodon (Cynodontia, Probainognathia) in the Triassic of southern Brazil and its biostratigraphic significance

The first occurrence of the enigmatic African probainognathian genus Aleodon in the Middle-early Late Triassic of several localities from the state of Rio Grande do Sul in southern Brazil is reported and a new species of Aleodon is proposed based on the specimens from Brazil.

A new gomphodont cynodont (Traversodontidae) from the Middle–Late Triassic Dinodontosaurus Assemblage Zone of the Santa Maria Supersequence, Brazil

The tetrapod faunas from the terrestrial Middle–Late Triassic basins of Africa and South America are among the richest in the world, especially in non‐mammalian cynodonts. Despite the great abundance

A new cynodont from the Santa Maria formation, south Brazil, improves Late Triassic probainognathian diversity

The fossil record of non‐mammaliaform probainognathian cynodonts is outstanding in the Late Triassic rocks of Brazil and Argentina. Approximately 15 genera are known, providing unique insights in the

Prozostrodon brasiliensis, a probainognathian cynodont from the Late Triassic of Brazil: second record and improvements on its dental anatomy

The second known specimen (CAPPA/UFSM 0123) of Prozostrodon brasiliensis is described, showing that the adult individual has more postcanine tooth morphotypes than the juvenile one.

The Triassic eucynodont Candelariodon barberenai revisited and the early diversity of stem prozostrodontians

The reinterpretation of Candelariodon as a probainognatian cynodont more derived than Probainognathus and the rich Brazilian fossil record document an important adaptive radiation of non-mammaliaform prozostrodontians and closely related forms prior to the origin of the mammaliaform clade.

New cynodonts (Therapsida, Eucynodontia) from the Late Triassic of India and their significances

The Upper Triassic Tiki Formation of India has yielded several new cynodont taxa, which are described on the basis of multiple isolated teeth and a jaw fragment, and such a tooth morphology occupies an intermediate position between the non-mammalian Cynodonts and the early mammals.



A new prozostrodontian cynodont (Therapsida) from the Late Triassic Riograndia Assemblage Zone (Santa Maria Supersequence) of Southern Brazil.

Although the new taxon is based on few cranial elements, it represents a additional faunal component of the Triassic Riograndia AZ of southern Brazil, in which small-sized derived non-mammaliaform cynodonts, intimately related to the origin of mammaliaforms, were ecologically well succeed and taxonomically diverse.

A new carnivorous cynodont (Synapsida, Therapsida) from the Brazilian Mid-dle Triassic (Santa Maria Formation): Candelariodon barberenai gen. et sp. nov.

A new small cynodont, Candelariodon barberenai gen. et sp. nov., from the Middle Triassic of Brazil (Santa Maria Formation) is reported. The new taxon is represented by a partial mandible having some

A new non-mammaliaform eucynodont from the Carnian-Norian Ischigualasto Formation, Northwestern Argentina

61 ABSTRACT – The record of non-mammaliaformes eucynodonts from the Carnian-Norian Ischigualasto Formation is diverse and abundant, including a medium to large size herbivore and small carnivores.

Trucidocynodon riograndensis gen. nov. et sp. nov. (Eucynodontia), a new cynodont from the Brazilian Upper Triassic (Santa Maria Formation)

An almost complete skeleton of a new carnivorous cynodont from the Upper Triassic of Southern Brazil, Trucidocynodon riograndensis gen. nov., is described and the overall morphology of the astragalocalcaneal complex is similar to that of Diademodon and of the therocephalian Bauria.

A new carnivorous cynodont from the Ischigualasto Formation (Late Triassic, Argentina), with comments on eucynodont phylogeny

ABSTRACT The nearly complete skull of a recently discovered carnivorous eucynodont, Ecteninion lunensis, gen. et sp. nov., is described. This is the first new genus of carnivorous cynodont reported


A cladistic analysis of 32 taxa (two gorgonopsians, seven therocephalians and 23 cynodonts) and 96 craniodental characters places P. elegans as sister taxon of Eucynodontia, and indicates paraphyly for Therocephalia, with the whaitsiid Theriognathus identified as sisterTaxon of CynodontIA.

A new traversodontid cynodont from the Santa Maria Formation (Ladinian-Carnian) of southern Brazil, with a phylogenetic analysis of Gondwanan traversodontids

A phylogenetic analysis of traversodontids from Gondwana revealed a nonmonophyletic relationship for Scalenodon‘species’ from the Anisian Manda beds, and morphological trends of change in the dentition of traversdontids throughout the Triassic are suggested.

A new tritheledontid (Therapsida, Eucynodontia) from the Late Triassic of Rio Grande do Sul (Brazil) and its phylogenetic relationships among carnivorous non-mammalian eucynodonts

The presence of two kinds of upper postcanines in different replacement waves in Irajatherium could be a useful feature for inference of possible mechanism of dental differentiation among non-mammalian cynodonts.

A Middle Triassic Cynodont Fauna from Namibia and Its Implications for the Biogeography of Gondwana

ABSTRACT The upper Omingonde Formation of Namibia contains a diverse vertebrate fauna represented by amphibians, dicynodonts, archosaurs, therocephalians, and cynodonts, which is generally considered


A cladistic analysis of ictidosaurians supports its monophyly and indicates that they represent an ancestral condition that facilitated the development of the mammalian skull base constituted by the reduced pterygoids, the basisphenoid, and posteriorly thedevelopment of the presphenoid by the ventral extension of the braincase.
