Pictured on the facing page in the Smithsonian Engagement Calendar 2020 is ‘Xenacanthus, a freshwater spiny shark that lived in rivers and ponds during the Permian Period, 294-290 million years ago, preying on fishes, reptiles, amphibians and perhaps even large land carnivores that ventured close to the water.’ This Xenacanthus skull cast is on display with fossils of other aquatic creatures in the Hall of Fossils- Deep Time at the National Museum of Natural History.
