👉 The term "Rhincodontidae" refers to a group of extinct, highly specialized marine reptiles that lived during the Mesozoic era. They are known for their distinctive dental structures, which included a set of teeth with sharp incisors and molars, as well as an elongated snout with a tooth-like structure at the base. These reptiles were primarily adapted to feeding on small fish and crustaceans, but they also had some ability to climb trees or swim in water
