It is known from numerous complete but poorly-preserved specimens (known by Richard Owen as "batracholites") from the Intertrappean Beds of Worli Hill, Mumbai.

The stratigraphy of the specimens is disputed; they were originally dated to the Early Eocene, but later thought to be latest Cretaceous in age (66 mya).

[5][6] However, more recently, the intertrappean rocks around Mumbai have been dated to the late Danian, around 62.5 million years ago, representing the youngest eruptive event in the western Deccan volcanic province.

[2][7] The taxonomy of this genus is debated; it was previously classified within the Australian frog superfamily Myobatrachoidea by many authors, including Owen, but such a relationship is now considered dubious or untenable, with only some vertebral similarities linking the two groups.

[5][6][8] Alternatively, it may represent a member of the superfamily Sooglossoidea, another ancient group that is thought to have originated on Insular India during the Cretaceous.
