Trilobozoa refers to a phylum of extinct animals that lived during the early Cambrian period. These creatures are characterized by their three-lobed body, which gave rise to their name. Trilobozoa are one of the earliest known animals to have a hard exoskeleton, and they are believed to have played an important role in the evolution of arthropods. Some synonyms for trilobozoa include Bennettitales, Cycadophyta, and Lepidodendrales. These terms all refer to extinct groups of plants and animals that lived during the same time period as trilobozoa, and they provide insight into the complex ecosystems that existed millions of years ago.
