The Ichthyosaur Navigating a Deep Ocean Canyon
Swimming between steep rock walls, an ichthyosaur moves through the sheltered corridor of a sunken ocean canyon. The underwater landscape includes prehistoric shells resting along the rocky floor alongside a broad fallen log that drifted into the marine channel.
Remarkable Features of Prehistoric Sea Canyons
Submerged marine canyons formed over millions of years as ocean currents and ancient river channels carved deep pathways through coastal rock formations. These underwater valleys collected drifting organic material like fallen wood, creating rich feeding grounds for predatory sea reptiles.
