“…The modern frog pelvis appeared first in the Jurassic Prosalirus and Notobatrachus (Shubin and Jenkins, 1995;Báez and Nicoli, 2008), characterized by a nonexpanded sacral diapophysis directed posterolaterally, smooth dorsal surface of ilium and urostyle without a ridge, and a bicondylar sacral-urostyle articulation. This set of characters is also seen in the most primitive living frogs Ascaphus + Leiopelma, all Early Cretaceous fossil discoglossids and pipoids from Spain (Báez and Sanchiz, 2007;Báez, 2013), and the Early Cretaceous fossil neobatrachians from Brazil (Báez et al, 2009). All the three previously known Jehol frogs are characterized by moderately expanded and hatchet-shaped sacral diapophysis, bicondylar sacral-urostyle articulation, and smooth ilia and urostyle (Gao and Wang, 2001;Gao and Chen, 2004).…”

“…The Early Cretaceous Crato Formation (Aptian-Albian) of northeastern Brazil is also known for well-preserved fossil frogs, representing one of the best Gondwanan Cretaceous frog fossil assemblages (Báez et al, 2009). Three fossil species, Arariphrynus placidoi, Euricephalilla alcinae and Cratia gracilis, were identified and included in the clade Neobatrachia, representing the earliest neobatrachians known worldwide (Báez et al, 2009). Genibatrachus baoshanensis shares with these frogs the presence of the palatine, nonimbricate neural arches, and nonexpanded and posterolaterally directed sacral diapophysis.…”

No mesocretáceo, novamente são encontrados restos de anuros da superfamília Pipoidea na Patagônia argentina, especificamente na Formação Candeleros (Eocenomaniano) aflorante na província de Rio Negro, noroeste da Patagônia: Avitabatrachus uliana Báez, Trueb & Calvo 2000(BÁEZ et al, 2000.…”

“…less research focus, geopolitical instability, more limited exposures of sedimentary rocks of appropriate age and depositional environments, transportation challenges), there the results have been more modest. Nevertheless, the former Gondwanan continents clearly preserve significant lissamphibian and squamate fossils, including some intriguing occurrences for both clades, such as: a moderately diverse assemblage of neobatrachian anurans in the Early Cretaceous of Brazil (Báez et al 2009); Late Cretaceous putative salamanders in Africa and South America Martill et al 2013;Rage et al 1993); and a surprisingly diverse snake assemblage of reportedly early Late Cretaceous age in Sudan (Werner and Rage 1994). We can expect the Gondwanan lissamphibian and squamate records to improve as fieldwork and research continues in the Southern Hemisphere and, consequently, to provide new perspectives into the evolutionary histories of both clades.…”
