👉 Rhotidoids are a group of extinct marine reptiles that lived during the Cretaceous period, around 65 million years ago. They were characterized by their long limbs and large, blunt-toothed jaws, which allowed them to reach high points on land like sea turtles or cranes. Rhotids included a wide range of species, from small, primitive creatures to larger, more complex animals with unique adaptations for aquatic life.
