“…According to Dunlap (1960), the gracilis minor in Rhinophrynus originates as a thin, broad sheet from the skin of the ventral side in the posterior half of the body, extends laterally onto the ventral surface of the thigh and inserts widely at the knee aponeurosis. It is especially large in Xenopus, whereas in the discoglossids it is moderately developed, and the muscle is absent in Hymenochirus (Cannatella, 1985) and Rheobatrachus (Davies & Burton, 1982).…”

Pelvic and thigh musculature in frogs (Anura) and origin of anuran jumping locomotion

et al. 2008

Comparative analysis of the anuran pelvic and thigh musculoskeletal system revealed that the thigh extensors, responsible for the initial phase of jump, the propulsive stroke in swimming and, if used asynchronously, also for walking, are least affected by the transformations observed between anurans and their temnospondyl ancestors (as reflected in contemporary caudates). The iliac shaft and urostyle, two of the most important anuran apomorphies, represent skeletal support for muscles that are mostly protractors of the femur or are important in attaining a crouching position, a necessary prerequisite for rapid escape. All of these muscles originate or insert on the iliac shaft. As the orientation of the pubis, ischium and ilium is the same in anurans, caudates and by inference also in their temnospondyl ancestors, it is probable that the pelvis was shifted from the sacral vertebra posteriorly along the reduced and stiffened tail (urostyle) by the elongation of the illiac shaft. Thus, the original vertical orientation of the ilium was maintained (which is also demonstrated by stable origins of the glutaeus maximus, iliofemoralis and iliofibularis on the tuber superius) and the shaft itself is a new structure. A review of functional analysis of anuran locomotion suggests some clear differences from that in caudates, suggesting that terrestrial jumping may have been a primary locomotor activity, from which other types of anuran locomotion are derived.

“…While there is some disagreement about the monophyly of the Myobatrachidae (Tyler et al, 1981;Ford and Cannatella, 1993;Hay et al, 1995;Ruvinsky and Maxson, 1996), there is general consensus that the Australian and New Guinea species are each others' closest relatives and most workers recognize two myobatrachid subfamilies, the Myobatrachinae with 12 genera and 71 species and the Limnodynastinae with nine genera and 47 species (Parker, 1940;Lynch, 1971;Tyler et al, 1981;Farris et al, 1982). The recognition of a third subfamily, Rheobatrachinae, comprising only the genus Rheobatrachus (Heyer and Liem, 1976;Davies and Burton, 1982) is contentious Farris et al, 1982;Hutchinson and Maxson, 1987;Ford and Cannatella, 1993).…”

Calyptocephalella gayi is one of over 6,000 neobatrachians arranged into two main groups, Hyloides and Ranoides. Phylogenetically, C. gayi is placed in Australobatrachia, a Gondwanan clade that is either the most basal clade of Hyloides or the sister group of Hyloidea, depending on the cladistic hypothesis; as such, this species is a key taxon in the study of the early evolution of Neobatrachia. The ontogeny of the postcranial skeleton of C. gayi is described in this article. The description is based on pattern of chondrification and ossification of skeletal elements in a growth series of tadpoles, on juveniles and adult individuals. Particular attention was devoted to some developmental aspects and morphological traits of the adult skeleton. The body of Presacral Vertebra VIII is formed from three centers of ossification, in contrast to the usual two dorsolateral centers observed in the remaining vertebrae of C. gayi, as well as in most anuran taxa for which the development of the axial skeleton is known. Each half of the pelvic girdle arises from a single cartilaginous element. The early development of the autopodia of both the forelimb and hindlimb includes the presence of an additional chondral element, which occurs during the formation of Distal Carpal 5 and the transient formation of Distal Tarsal 4 before the latter is incorporated in the cartilaginous distal end of the fibular. Some osteological aspects of other australobatrachian anurans also are reviewed (e.g., presence of intervertebral discs) based on reports in the literature, as well as first hand observations. In the course of this study, it became evident that further osteological studies are needed to formulate a clear picture of the evolution of skeletal characters not only within Australobatrachia, but also within Neobatrachia.
