We know trilobites existed through fossil evidence. Trilobite fossils have been found in sedimentary rocks dating back to the Cambrian period, which began around 541 million years ago. These fossils exhibit characteristic features such as a hard exoskeleton divided into three lobes, giving them their name "trilobite." Their abundance and widespread distribution in the fossil record provide strong evidence for their existence in the past.
