Fossilized pollen grains,computer artwork. Pollen grains are reproductive structures produced by flowers. It is rare,but not impossible,for soft structures to be fossilized. Fossils are where an organic object has left a shape in rock,usually formed from soft mud that preserved the shape of the original object. Flowering plants only evolved about 135 million years ago | |
