Maiopatagium furculiferum (Luo et al. 2017; Meng et al. 2017; Late Jurassic (Callovian); 160 mya) was originally described as a pre-mammal haramiyid close to Sinoconodon. Here it nests with gliding multituberculates Vilevolodon and Arboroharamiya. The mandible is not known. The clavicle is robust here and fused with the interclavicle. The procoracoid and coracoid are poorly ossified and may be atavisms. A patagium has been described with a halo of thick straight hair.
