       Alveusdectes is an important discovery as it represents one of the last surviving diadectimorphs to live.‭ ‬Diadectomorphs‭ (‬those like Diadectes‭) ‬were reptilomorphs that rose to prominence during the Carboniferous,‭ ‬but they were eventually replaced by therapsids and true reptiles.‭ ‬What the discovery of Alveusdectes tells us is that while their numbers declined during the Permian,‭ ‬some populations managed to hold on until the end of the Permian.‭ ‬At this time a major extinction event gripped the planet wiping out most of the animals,‭ ‬and so far there is no fossil evidence to suggest that diadectomorphs survived this.
       Alveusdectes would have been a quadrupedal herbivore that ate plants.‭ ‬Like relative genera,‭ ‬Alveusdectes was well adapted for grinding tough fibrous plants which would have been common in many of the harsh environments of the Permian.
