The holotype of Iberomesornis was probably not immature. Cervical ribs are
fused to their vertebrae, no sutures between neural arches and centra are
indicated, the first four sacrals are fused, the pygostyle is fused, the
sternal ribs are ossified, the sternum is large with elongate posteroventral
processes, the tibiotarsus is completely fused and the metatarsals are fused
