These were all smallish birds, maybe 15–20 cm long in life, except E. walkeri which was probably more than 25 cm long.
Since only the coracoids are known, the phylogenetic position of these taxa is somewhat unresolved. While they do resemble the more advanced Enantiornithes more than they do any other bird, confirmation of their placement with Euenantiornithes would still require more material.
