The new study Tom Holtz, Thomas R ,challenges recent view of Spinosaurus suggesting that whilst it likely fed from the water, and may have swum, it wasn't well adapted to the life of an aquatic pursuit predator. Instead it was like a giant (if flightless) heron or stork - snatching at fish from the shoreline while also taking any other small available prey on land or in water. They found that whilst there were several pieces of evidence that contradicted the aquatic pursuit predator concept, none contradicted the wading heron-like model, and various lines of evidence actively supported it.the illustration shows how a spinosaurus is going to eat a mawsonia that was thrown ashore during high tide.
