(A) Dorsal view. (B) Lateral view. (C) Ventral view. (D) Mouth structure. [1] Gosner stage is a generalized system of describing stages of embryonal and larval development in anurans (frogs and toads). The Gosner system includes 46 numbered stages, from fertilized embryo (stage 1) to the completion of metamorphosis (stage 46).
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 quadrate bone is a skull bone in most tetrapods, including amphibians, sauropsids (reptiles, birds), and early synapsids. In most tetrapods, the quadrate bone connects to the quadratojugal and squamosal bones in the skull, and forms upper part of the jaw joint.
They have an average skull width of 12.02±0.36 mm and an average skull length of 9.38±0.14 mm. [8] The dorsal body of H. japonica is green/brown and the ventral body is white. [5] H. japonica is also characterized by a dark spot on the upper lip below the eye. [5] Female H. japonica, on average, are larger in size compared to male H. japonica ...

In the auditory system, the columella contributes to hearing in amphibians, reptiles and birds. The columella form thin, bony structures in the interior of the skull and serve the purpose of transmitting sounds from the eardrum. It is an evolutionary homolog of the stapes, one of the auditory ossicles in mammals.
Diagram of flower parts. In botany, floral morphology is the study of the diversity of forms and structures presented by the flower, which, by definition, is a branch of limited growth that bears the modified leaves responsible for reproduction and protection of the gametes, called floral pieces.
Polypedates maculatus, the Indian tree frog, [1] or Chunam tree frog, is a common species of tree frog found in South Asia. It was described by John Edward Gray in 1830. [2] Although now considered as a separate species again, for a time, the Himalayan tree frog was considered as a subspecies of the Indian tree frog (as P. m. himalayensis). [1]
