       Though only a small animal,‭ ‬as of‭ ‬2015‭ ‬Erpetonyx is the earliest known appearance of a parareptile.‭ ‬This is an important discovery as it helps to fill a gap in our understanding of the evolution of reptiles.‭ ‬The original describers have also speculated that Erpetonyx is a possible bolosaurid.
