The prolacertids were historically placed within the paraphyletic group Prolacertiformes along with other basal, long-necked archosauriforms like Protorosaurus and the tanystropheids. However, more recent research has shown that the prolacertids were only distantly related to other "prolacertiforms", and were instead among the closest relatives of Archosauriformes.[4]
