Massive Animal Feces

Where Massive Animal Feces comes from

Massive Animal Feces is a fertilizer source in ARK: Survival Evolved and ARK: Survival Ascended. The ARK Wiki names the Brachiosaurus, Oasisaur, Titanosaur and Dreadnoughtus as the only creatures that produce it in ASE, and it drops from them on its own every so often. As the wiki puts it, eating one will probably kill you.

Fertilizing crops

Put into the inventory of a Crop Plot, one Massive Animal Feces adds 35,000 fertilization points. A Compost Bin can also turn it, together with Thatch, into Fertilizer, but the ARK Wiki calls this partly not worth it: one Fertilizer holds 54,000 points, while 2 of these feces placed directly in plots give 70,000 and 3 give 105,000. Composting only makes some sense when a single Massive Animal Feces goes in with 2 smaller feces, and not when those are 2 Large Animal Feces or a Large plus a Medium Animal Feces.

Dung Beetles

Since patch 243.2 it no longer works for taming Dung Beetles, unlike the smaller sizes of feces. A Dung Beetle with a high enough weight stat can still convert it, turning each one into 16 bags of Fertilizer and 14 Oil.

Weight and spoilage

Each one weighs 35 and the stack size is 1. According to the ARK Wiki it spoils after 10020 seconds. Our records list it on 6 maps, including The Island, Scorched Earth and Ragnarok.
