  • Indeterminate fragments of stem-carettochelyids are also known from the Cenomanian aged Bayan Shireh Formation, Mongolia, which were originally assigned to "Anosteira" shuwalovi Chkhikvadze in Shuvalov and Chkhikvadze, 1979, which Joyce 2014 regarded as a nomen dubium. from the Early Eocene (Lutetian) aged Kuldana Formation, Khyber Pakhtunkhwa, Pakistan was considered to be a nomem dubium and an indeterminate carettochelyid by Joyce, 2014, due to the fragmentary and heavily eroded nature of the specimens.
