The archaeologist villager is a new type of Minecraft villager added by the Fossils and Archeology: Revival mod. They spawn in villages like normal villagers do and trade mod items for emeralds. Besides searching villages, other ways to find them are by using spawn eggs or healing zombie villagers. Archaeologists now spawn at fossil dig sites or tar pit sites. They may occasionally own a pet dinosaur. They are more rare than all other types of Minecraft villagers.
These villagers act just like any other villager; they are passive mobs with 20 hp that walk around during day and hide inside at night. They run from zombies, interact with other villagers, and trade with you when right-clicked. Some of their trades include bio-fossils, javelins, essences of chicken, animal meat, fern seeds ect.
