👉 The term "Algophagidae" refers to a family of extinct marine reptiles that lived during the Late Cretaceous period, around 68 million years ago. These animals were known for their long necks and powerful jaws, which they used to hunt insects and other small prey like spiders. They are classified as "carnivorous" and were able to survive on a diet of plant matter alone, making them a significant part of the Mesozoic Era's biodiversity.
