Dinosaurs and the survival concept may lead to compare it to ARK, but it is quite different. Other that the overal (huge) difference in graphics and world map, DS is a real ecosystem simulation, with real emergent biology, for both plants and animals, and even lakes, terrain and weather (seasons, day length etc) chance according to the environment. ARK is set on an island used to save different species from different ages, while DS is set at the end of the cretaceous era (and the mai ncharacter went there with a time machine or something, still up to decide). Also, ARK is focused on multiplayer coop survival, DS, when playing survival mode, is only single player with no NPC,
