The Trouble With Trilobites

Trilobites were highly successful marine arthropods that thrived for over 270 million years. They evolved complex features like legs and eyes, allowing them to dominate Cambrian seas. Despite surviving multiple extinction events, they eventually vanished due to environmental changes and new predators. Their story highlights both their resilience and the challenges of survival, offering insights into the history of life on Earth.
