Seagrass stems with attached roots from the type area of the Maastrichtian Stage (NE Belgium, SE Netherlands): Morphology, anatomy, and ecological aspects

Seagrasses are the only seed plants to have invaded marine environments successfully. Seagrass fossils are both rare and have received scant attention so far. However, among the limited number of plant fossils from marine strata in the Maastrichtian type area, remains of seagrasses are relatively common.
