These vast grass covered areas are found deeper into the continents, and they are usually located between the forests and the deserts.

For an organism to get preserve and form fossil, the organism must be comprised of a hard part and they should be immediately buried by the sediments after their death. The body of the organism must be detached from the oxygenated environment so that the body does not get damaged.
Mudflats usually refers to the coastal wetland areas that are commonly formed in the inter-tidal zone. They are also considered as the tidal flats. These mudflats are comprised of fine sediments that are carried from other places and are rich in organic matter and there is low or absence of oxygen. This helps in the preservation of fossils.
For example, clams with calcite shells that lived on the mudflat are most likely to be preserved in geological history.
