Spawn Eggs

Fossils and Archeology: Revival spawn eggs function just like vanilla spawn eggs. They are only available in creative mode and spawn untamed adult mobs when right clicked. Pre-7.3, prehistoric creatures would spawn with a random subspecies. After 7.3, they spawn with random genders. Using one of these spawn eggs on an already-spawned mob creates 1 day old version of it.
