Dil from The Land Before Time IV: Journey through the Mists is a Big-mouth Belly dragger. Sarcosuchus appears in The Land Before Time X, attacking Littlefoot and later his friends (both as they traversed the swamp), and Rutiodon appears in The Amazing Threehorn Girl, chasing the gang until Cera causes a rockslide and later returning with more.
