It is formed from years in the seed proccess.
The little balls found in seaweed are called air bladders or pneumatocysts. They are formed through a process called photosynthesis, where the seaweed produces oxygen gas that gets trapped in specialized structures within the seaweed, creating the buoyant balls. These air bladders help the seaweed float and stay upright in the water, allowing it to access sunlight for photosynthesis.
I think it formed in the tertiary because that's when the first flowering plants formed, however, it could also be the Devonian because that was the age of fishes.
