Few fossil animals are as popular with the public, as abundant in the fossil record, or as important to the study of past life on Earth as trilobites. These ocean-dwelling arthropods came in an amazing variety of shapes, sizes, and lifestyles, with many thousands of identified species, and they persisted on our planet for more than 270 million years. And best of all, they left behind an incredible fossil record giving us insights into their evolution, life history, and ultimate extinction.

In the news: evolution of gliders, a weird worm, tiny marsupial lions, and dino DNA?
