|Fossilized Seeds & Spores|
|A fossilized lycopodiophyta spore.|
Fossilized seeds and spores are fossilized remains of prehistoric plants. They are the plant versions of DNA in all respects. When you put a plant fossil in an analyzer, you have the chance of producing a random species of fossilized seed or spore. When this occurs, the player will get the "Plants from the Past" achievement. The fossilized seed or spore then must be placed in the culture vat in order to convert it into a seed or spore of the same species. If a fossilized seed or spore fails, the culture vat will break, creating a water source block and dropping a Failure Plant along with the contents of the culture vat.
