Última Tetrapod footprints from the Triassic of Patagonia: reappraisal of the evidence Ameghiniana Domnanovich,Nadia S.; Marsicano,Claudia A.. To date, the only known Triassic tetrapod footprints in Patagonia are those from the Los Menucos Basin, Río Negro province. The footprints occur at several levels in the Vera Formation in finegrained tuffaceous sandstones interbedded with tuffaceous mudstones that contain a rich &" Dicroidium type Flora&". A revision of the original material described by Casamiquela and study of undescribed specimens from the same locality are presented herein. Previous assumptions about the large number of tetrapod groups represented by the footprint assemblage are not corroborated by the available evidence. However, this new analysis supports former propositions about the relative abundance and high diversity of small therapsids, probably theriodonts. This...

Ano: 2006 URL: http://www.scielo.org.ar/scielo.php?script=sci_arttext&pid=S0002-70142006000100005 New information on Riograndia guaibensis Bonaparte, Ferigolo & Ribeiro, 2001 (Eucynodontia, Tritheledontidae) from the Late Triassic of southern Brazil: anatomical and biostratigraphic implications Anais da ABC (AABC) Soares,Marina B.; Schultz,Cesar L.; Horn,Bruno L.D.. The tritheledontid Riograndia guaibensis was the first cynodont described for the "Caturrita Formation" fauna from the Late Triassic of southern Brazil (Santa Maria 2 Sequence). The type materials did not preserve anatomical information regarding braincase, occiput, basicranium, zygomatic arch, postdentary bones and craniomandibular joint. Here new materials are described and supply the missing information. Riograndia shows a suite of important anatomical features quite derived among the non-mammaliaform eucynodonts, such as the partial closure of the medial orbital wall and braincase, extensive secondary osseous palate, wide primary palate, basicranium with jugular foramen separated from the periphery of fenestra rotunda, narrow zygomatic arch and much...
