The discovery of frog fossils in the Chinle Formation in Arizona is quite significant because it is the third record of Late Triassic lissamphibians after Chinlestegophis and an unnamed relative from Wyoming. While salientians have been found in the Early Triassic, no caudatan has been found in Triassic deposits, but Chinlestegophis helped to begin filling a gap in the fossil record of early lissamphibians. The long-standing scarcity of Triassic lissamphibian taxa might largely be responsibility for the past debate over whether or not extant amphibians are descended from temnospondyls, because Pardo et al. (2017) note that Chinlestegophis shares many skull features with metoposauroid temnospondyls. Since Triadobatrachus had a short tail, the earliest frog relatives may have had a short tail, because Gerobatrachus had a combo of a frog-like head and salamander like tail.

Interesting article and comment.

But what does the suicidal frog in the phytosaur's mouth think he is up to. 

Hopping mad.
