Most Triassic frogs are known from high latitudes (Triadobatrachus, for example, is from Madagascar, which was then farther from the equator than it is now). Conversely, this new one from the Chinle formation in Arizona, is from what was then an equatorial region. The describers don't give it a name, but assign it to the frog stem-group. The specimens are a partial maxilla (part of upper jaw) and several ilia (the longest hip bones).

When you analyse it closely, that reconstruction is pretty depressing  :(

Regardless, nice find  :)

Who knows? Maybe if it stays really still, the phytosaur wouldn't notice... oh... wait...

Not if you look at it from the phytosaur's perspective. How often does a cheeseburger just climb into your mouth?
