Although it was initially thought that the maxilla and premaxilla were freely movable, detailed anatomical studies show that this is not the case.

Based on morphology of the cranio-vertebral articulation and internal structure of the head, lysorophians are usually considered to be related to the Microsauria, although the pattern of bones of the skull is somewhat different.

[3][5] Swim traces referrable to lysorophians have been found at the Robledo mountains of New Mexico, an area famous for its Permian tetrapod trackways.

When originally described in 2003, Serpentichnus tracks were argued to have been formed by a long-bodied animal with small limbs, moving in a "sidewinding" motion along a riverbed.

These sources argue that the grooves were "tool marks", meaning that they were formed by rocks or vegetation brushing against the riverbed while being carried by a current.
