Macrodontids

Macrodontids are a family of extinct rays that lived during the Cretaceous period. These cartilaginous fish are known from fossilized remains, primarily their teeth. The most distinguishing feature of macrodontids, as their name suggests, is their exceptionally large teeth compared to their overall body size. These teeth were typically broad and flattened, adapted for crushing and grinding. The diet of macrodontids is believed to have consisted of hard-shelled prey such as mollusks and crustaceans. Fossil discoveries of macrodontids have been made in various locations worldwide, indicating a widespread distribution during their existence. Their evolutionary relationship places them within the broader group of sharks and rays. The decline and eventual extinction of macrodontids are thought to be linked to environmental changes or competition with other marine predators at the end of the Cretaceous period. Study of their skeletal and dental morphology provides insights into the paleoecology and diversity of ancient marine ecosystems.
