Carnivorous crocodile-like monsters used to terrorize the Caribbean

Thousands of years ago, mysterious crocodile-like creatures called sebecids roamed the Caribbean islands, despite similar predators going extinct on South America during the same period. Fossils found in Cuba, Puerto Rico, and the Dominican Republic revealed these ancient relatives of crocodiles walked across the mainland when sea levels were low, potentially using land bridges or hopping between islands after their disappearance elsewhere. This discovery bridges the gap between prehistoric ecosystems on both continents, offering new insights into how these creatures adapted to life on land.
