Vizelettiidae

Vizelettiidae is a family of extinct cartilaginous fishes, specifically sharks, that lived during the Carboniferous period. Fossil remains of these sharks are found in marine deposits from that era. The family is characterized by certain features of its teeth and jaw structure, which distinguish it from other shark families of the Paleozoic. Vizelettiidae sharks were likely predators, feeding on smaller marine organisms. Their fossilized teeth are the most commonly recovered elements, often exhibiting unique morphologies that allow for taxonomic classification. The distribution of Vizelettiidae fossils indicates a presence in marine environments across different regions during the Carboniferous. Research into this family contributes to our understanding of early shark evolution and the paleoecology of ancient marine ecosystems. The exact phylogenetic relationships of Vizelettiidae within the broader shark lineage are still a subject of ongoing paleontological study.
