The marshy conditions of the dinosaur freeway (the reason its footprints formed, and have survived) may, though, have favoured crocodilians over predators that had evolved on drier land.
With a definition, of course, something like a marshy area of land where the soil near the surface is saturated or covered with water forming a special habitat for wildlife.
Thanks to their planting of eelgrass seeds over the marshy land, the once-barren ecosystem is now flourishing, and the seagrasses are storing a ton of carbon in their root systems to boot.
