Examples showing character states concerned with the absence or presence of a connection between interosternite 7/8 and the sella turcica (character 19) and the absence or presence of a connection between the junction plate and the sella turcica (character 21) in the axial skeleton seen from posterior (A, B, D, E, G, H). Note that in the species in which interosternite 7/8 is connected to the sella turcica (character state 19(0); B, E), the junction plate does not form a cavity, while in the species without a connection (character state 19(1); G, H), a junction plate cavity is present (I). IntSt 7/8 interosternite between thoracomeres 7 and 8, JP junction plate, JPCav junction plate cavity, ST sella turcica
