Matground
A matground is a strong surface layer of bacterial fauna that hardened the surface of seabeds in the Proterozoic and early Cambrian. It is sometimes called "elephant skin" from its appearance when found fossil. It is theorized that matgrounds disappeared when priapulid worms evolved to be big and strong and common enough to break the matground up when burrowing.[1][2][3][4]
