A giant sclerotic ring, an appressed metatarsus, large manual digits I-III, and a short scapula mark Eosipterus as a primitive germanodactylid, rather than a ctenochasmatid as Unwin, Lü and Bakhurina suggested in 2000. Presented in ventral view, the right wing, or what is left of it, is in purple. Presumeably this is the proximal portion because it matches in shape the other wing. The complete left wing is a redder sort of purple. Portions have torn away and now lie outside the wing digit. Note that the trailing edge approaches the pelvis (green) and proximal femur.
