A genus of large lung fish from the Mesozoic era that had powerful tooth plates shaped like horns, making them fierce predators in ancient freshwater ecosystems.
From Greek 'keras' (horn) + 'odous' (tooth). Named directly for the horn-shaped tooth structures that defined these prehistoric fish in scientific classification.
Ceratodus fossils show us that some fish were basically the bulldozers of ancient rivers, using massive horn-like teeth to crush and grind anything edible—and these designs inspire modern paleontologists to understand predator evolution!
