New golems buildable from archaeological fragment

Golems are very powerful and seem to come from another era. What if the iron golems were only a relic of the know-how of an ancient civilization and that it would be possible to find in archaeological sites fragments of ancient ore and object allowing us to summon other types of golems. The fragments would have different levels of rarity and would vary from biome to biome. Each golem would have different characteristics, and they would have their strengths and weaknesses. For example a one tall block golem that would move fast and could easily sneak under block, but would not have much health. A flying golem that would fly over the village and attack enemies in the sky, but which would be weak against mobs that shoot from a distance. A golem that would have the ability to follow the player to defend him ect .... They would provide a good help to the iron golem who sometimes cannot defend the village properly.
