Argentavis Kibble (MOBILE) is used to tame the Spinosaurus, and the Gasbags.To make Argentavis Kibble (MOBILE), combine Argentavis Egg, Citronal, Prime Meat Jerky, Mejoberry, Fiber, and Waterskin in a Cooking Pot. Start the fire and cook for 30 seconds. It spoils in 3 days.
If you need prime meat, kill a few stegosauruses or low level spinosauruses, then quickly get the prime meat into a fridge or preserving bin. Use it to make the kibble you need by adding sparkpowder, oil and the cooked prime meat (or uncooked) in a preserving bin to make the jerky.
