Omnivoropterygidae(meaning "omnivorous wings" ) is afamilyof primitiveavialandinosaursknown exclusively from theJiufotang FormationofChina,though putative omnivoropterygids are known from theMaevarano Formationof theMaastrichtianofMadagascar.[1]They had short skeletal tails and unusual skulls with teeth in the upper, but not lower, jaws. Their unique dentition has led some scientists to suggest anomnivorousdiet for them.[2]The family was named byStephen A. Czerkas&Qiang Jiin 2002, though its junior synonymSapeornithidaeis often used instead, though it was named four years later in 2006.[3]It is the only named family in the orderOmnivoropterygiformes.
