Fossil frogs are rarely found as multiple articulated skeletons, therefore the discovery of this taxon has provided important insight into anuran evolution. [5] [6] The holotype, IVPP V11525, is known from a nearly complete skeleton exposed in a dorsal view on a shale slab.
The eyes are prominent and forward-facing. It has an array of sharp, pointed projections on the head, and the skin on the head is fused to the skull. The legs are long and slender and the digits have adhesive discs at the tips. The dorsal surface is pale brown or gray, with irregular dark markings. [3]
This species is a relative large frog with a snout–to–vent length of 5.8 to 8 cm (2.3–3.1 in). It has numerous sharp, pointed projections on the head and dorsal surface, hence the common name. [7] The skin on the head is fused to the skull and the tympanum is very large. The legs are long and slender and the digits have adhesive discs at ...
Kermit the Frog meet Kermitops gratus, the most recent ancient amphibian to be identified after examination of a tiny fossilized skull that once sat unstudied in the Smithsonian fossil collection ...
Temporal fenestrae in relation to the other skull openings in the dinosaur Massospondylus, a type of diapsid. The supratemporal fenestra, also called the upper temporal fenestra, is positioned above the other fenestra and is exposed primarily in dorsal (top) view. In some reptiles, particularly dinosaurs, the parts of the skull roof lying ...
In addition, they proposed that the skulls represented the most derived phytosaur species in North America, due to their supratemporal fenestrae being hidden in dorsal view. [1] CM 69727, the holotype skull of R. bermani. A third skull (CM 69727) was discovered by D.S. Berman in the 1980s.

Dorsal view of a waterfall frog in Far North Queensland, Australia Tadpole. The waterfall frog is large in size, reaching 5.5 cm in length. The dorsal surface is mottled with puck brown. The patterning on the back is similar to its habitat, allowing for effective camouflage against granite.
