Skeletal diagram featuring the optimal remains of the holotype of Graciliceratops mongoliensis: ZPAL MgD-I/156.[1] Found in the Bayan Shireh Formation, in the original description the remains were referred to the genus Microceratops (now obsolete).[2] However, Sereno in 2000 noted that there was no base for this referral, then, he created a new genus and species for this specimen.[1] The holotype is very fragmented (specially the skull), consisting of:[2] Fragmented skull; 4 cervical, 12 dorsal and 7 sacral vertebrae; right scapula; proximal end of left scapula; left coracoid; right humerus, radius and fragmentary ulna; proximal and distal end of left humerus; proximal fragments of both pubis; fragments of both illium and fragment of right ischium; right femur, tibia and nearly complete pes; distal part of left tibia, fragmentary left pes; tarsals and isolated ribs.[2] The sacral vertebrae are not fused, an indicator of the immaturity of this specimen; the estimated adult size is about 2 meters long or similar to Protoceratops.[2][1] Right quadratojugal, quadrate and fragmentary jugal were reversed in order to get an optimal view. © PaleoNeolitic · CC BY-SA 4.0 · Wikimedia
