Genus Ceratodus refers to a group of prehistoric lungfish species that belonged to the family Ceratodontidae. These lungfish are often considered living fossils due to their ancient lineage and unique characteristics. The genus Ceratodus is known to have existed from the Late Triassic to the Early Cretaceous periods, approximately 205 to 100 million years ago.
Members of the genus Ceratodus were primarily freshwater inhabitants and had elongated bodies with flattened heads. They were characterized by their tooth plates, which were composed of sharp ridges and specialized for grinding plant material and crushing prey. These lungfish had sturdy, lobed fins that allowed them to navigate shallow waters and even survive in oxygen-poor environments by gulping air at the surface.
Within the genus Ceratodus, various species have been identified based on differences in size, tooth morphology, and geographical distribution. Fossils of these creatures have been discovered in several locations around the world, including Australia, South America, Africa, and Europe.
Today, no living species from the genus Ceratodus exist, but they are believed to have played a significant role in the evolutionary history of lungfish. Their fossils provide crucial insights into the development and adaptations of ancient fish species, contributing to our understanding of the evolution of life on Earth.
