The Large Mosasaur Swimming Around a Table Reef
A giant mosasaur navigates through shallow tropical waters surrounding a broad, flat-topped reef formation. Beside the marine table reef, a vertical stone pillar rises from the seabed while a massive sea shell sits anchored among coastal rock structures.
The Ecosystem of Prehistoric Table Reefs
Ancient table reefs were shallow limestone structures built up by coral-like organisms and marine algae over hundreds of years. The flat tops of these reefs caught abundant sunlight, creating vibrant ecosystems that attracted schools of prehistoric fish and large hunting sea reptiles.
