The type and only species is W. pobeni, known from the holotype, an isolated preserved in opal, as well as a secondary referred dentary. It is thought to have co-existed with multiple other ornithopods of different sizes and lineages.

First discovered in 2012, it was named in 2019 with the type and only species being Adynomosaurus arcanus. It is only known from scant material, but is distinguished from other hadrosaurs by its weakly developed shoulder blade which would have had underdeveloped musculature, which lends it its scientific name, partially from the Greek word for "weak". Its exact relationships with other hadrosaurs remain unresolved, with it not consistently being recovered as a relative of any other spec

Sefapanosaurus was an early, herbivorous sauropodomorph dinosaur occurring in the southern regions of Gondwana some 200 million years ago in the Late Triassic or Early Jurassic. The sauropodomorphs were the dominant terrestrial herbivores throughout much of the Mesozoic Era, from their origins in the mid-Triassic (approximately 230 Ma) until their decline and fall at the end of the Cretaceous (approximately 66 Ma). A distinctive feature of this dinosaur is the cross-shaped astragalus or talus bone in its ankle. The generic name is derived from the Sesotho word sefapano, meaning ‘cross’ and the

The genus contains a single species, Tharosaurus indicus, known from a fragmentary skeleton including several vertebrae and a rib. When it was named in 2023, Tharosaurus was interpreted as the earliest known diplodocoid and the first member of this clade described from India. However, a later revision of the fossil material argued for a position outside of this clade, as an indeterminate eusauropod. This revision could not fi
