Falciferidae
Falciferidae is a family of extinct ray-finned fish that lived during the Triassic period. These fish are characterized by their distinctive dorsal fin, which is long and falciform, meaning it is shaped like a sickle or scythe. This prominent fin is the defining feature from which the family derives its name. Falciferids possessed a streamlined body, adapted for swimming, and typically had scales covering their bodies. Their teeth were generally small and pointed, suggesting a diet of smaller aquatic organisms.
Fossils of Falciferidae have been discovered in various marine sedimentary deposits dating back to the Middle
