Because of the small amount of material, Sinocoelurus has attracted little attention since its description, outside of reviews. It is usually considered a nomen dubium of either coelurosaurian\coelurid affinities (if the source predates the acceptance of Coelurosauria as a wastebasket taxon as traditionally used), or uncertain theropod affinities (if published after this).
Because of the small amount of available specimens, Sinocoelurus has been relatively overlooked since its initial description. It is typically categorized as either a member of the coelurosaurian group or an uncertain theropod lineage depending on the source's publication date and classification system.
