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

Abstract: We report here on a new prozostrodontian cynodont, Botucaraitherium belarminoi gen. et sp. nov., from the Late Triassic Riograndia Assemblage Zone (AZ) of the Candelária Sequence (Santa Maria Supersequence), collected in the Botucaraí Hill Site, Candelária Municipality, state of Rio Grande do Sul, Brazil. The new taxon is based on a single specimen (holotype MMACR-PV-003-T) which includes the left lower jaw, without postdentary bones, bearing the root of the last incisor, canine and four postcanines plus one p… Show more

“…The section shows occasional rithmic intervals with millimetric mudstone layers, as well as occasional mud intraclasts. The fossil record of the locality includes the dicynodont Jachaleria candelariensis Araújo & Gonzaga, 1980, the prozostrodontian cynodont Botucaraitherium belarminoi Soares, Martinelli & Oliveira, 2014, as well as an indeterminate phytosaur, a stereospondyl amphibian, and several isolated archosaur teeth (Araújo & Gonzaga, 1980;Dornelles, 1990;Kischlat & Lucas, 2003;Dias-da-Silva et al, 2009;Soares et al, 2014). An isolated tooth referred to Riograndia guaibensis was also reported by Soares et al (2011) from the upper portions of the outcrop.…”
