Mosasaurus Crossing an Underwater Rockslide
A mosasaurus travels across an expansive underwater rockslide situated at the base of a submerged cliff side. The scene features large scattered boulders, gently rippling sand beds, an ancient ammonite shell, and a waterlogged fallen tree trunk on the seafloor.
Geological Facts About Submerged Rockslides
Submarine rockslides occur along steep underwater slopes when tectonic movements or wave pressure cause cliff edges to collapse. Over time, submerged tree trunks and heavy rock piles create unique ecosystems that attract large ocean predators.
