It was classified as a member of Lepidosauromorpha, the clade of reptiles that includes lizards, snakes, the tuatara and their closest extinct relatives, at the time.

The study was conducted by performing high-resolution microfocus X-ray computed tomography (micro-CT) scans on the fossil specimen of Megachirella to gather detailed data about its anatomy.

[2][3] However, a 2021 study found the genus to be a lepidosaur of uncertain position, in a polytomy with Squamata and Rhynchocephalia.

[4] Despite being found in marine deposits, the fossil of Megachirella shows no adaptation to aquatic life.

On the contrary, characteristics like the strong front legs, the shape of the claws, the well-ossified carpus and the hollow ribs lead one to think that this animal was well adapted to a terrestrial lifestyle.
