1. Zoo and Wild Animals Reborn. It also has several addons.

5. Jurassicraft
6. My own mod, when I release it, lmao
7. Abyss: Voice
8. End Reborn
9. Corvus
10. Cannibalism
11. Coherent Villages

Next time please put direct links in your list to make it easier to see the mods. Anyway most of them have been put on the todo list #1, but I prefer not to add things that aren't released yet so Fossils and Archaeology and your unnamed mod will have to wait to be in there.

https://minecraft.curseforge.com/projects/natural-fauna-mod-a-zawa-addon

These are the two ZAWA addons, BTW

Added to the list #1.

Feel free to post links to both unreleased mods you mentionned once they are available for 1.12.

Here are some other mods I've seen while looking around:

https://minecraft.curseforge.com/projects/story-of-life

https://minecraft.curseforge.com/projects/creature-whisperer

https://minecraft.curseforge.com/projects/tfa

These two also have mobs:

https://minecraft.curseforge.com/projects/historicized-medicine

https://minecraft.curseforge.com/projects/animalium

I should probably mention Bewitchment since it’s been out for a while now.
