Pecora ialah infraorder mamalia berkuku genap dengan pencernaan ruminansia. Kebanyakan ahli Pecora mempunyai pelengkap tengkorak yang menonjol dari tulang hadapan mereka; hanya dua genera yang tidak memilikinya, Hydropotes dan Moschus.^[2] Nama "Pecora" berasal dari perkataan Latin pecus, yang bermaksud "ternakan bertanduk".^[3] Walaupun kebanyakan pecoran mempunyai pelengkap tengkorak, hanya sebahagian daripadanya dipanggil "tanduk", dan ramai saintis bersetuju bahawa pelengkap ini tidak timbul daripada nenek moyang yang sama, tetapi sebaliknya berkembang secara bebas pada sekurang-kurangnya dua kali.^[2]^[3]^[4]^[5] Begitu juga, sementara Pecora sebagai satu kumpulan disokong oleh kedua-dua kajian molekul dan morfologi, sokongan morfologi untuk saling hubungan antara keluarga pecoran dipertikaikan.^[2]
