Elasmosaurus Gliding Past Sea Life
An Elasmosaurus with a remarkably long neck glides through the ocean depths. Floating ammonites drift nearby while underwater rocks and seaweed rest along the sea floor. The graceful marine reptile steers smoothly past subsea formations as sea creatures move through the surrounding water.
Ocean Environments of the Late Cretaceous
During the Late Cretaceous period, vast shallow seas covered large areas of the continents, creating rich marine ecosystems. Ammonites with coiled spiral shells floated in vast schools through these sunlit ocean waters. The long neck of Elasmosaurus allowed it to approach schools of ammonites and small fish without casting a large shadow overhead.
