What were trilobites? Trilobites are a group of extinct marine arthropods that first appeared around 521 million years ago, shortly after the beginning of the Cambrian period, living through the majority of the Palaeozoic Era, for nearly 300 million years. First, the now-storied trilobite beds of Morocco started to produce Cambrian-age Paradoxides trilobites of prodigious size… and in equally prodigious numbers.
