Peronopsis Trilobites Wheeler Shale Formation, House Range, Millard Co., Utah, USA Cambrian Era (510 Million Years Ago) Peronopsis (meaning "broach-like" or possibly "boot-like") is a genus of trilobite restricted to the Middle Cambrian. Its remains have been found in Asia, Australia, Europe, and North America. Like all Agnostida, members of the Peronopsidae are diminutive, with the headshield (or cephalon) and tailshield (or pygidium) of approximately the same size (or isopygous) and outline. Like all Agnostina, Peronopsidae have only two thorax segments. The cephalon and pygidium usually have a complete set of furrows. The preglabellar furrow - between the front and the central raised area of the cephalon (or glabella) - is lacking or incomplete. The cephalon carries no spines. The border around the pygidium is not forked. Kingdom: Animalia Phylum: Arthropoda Class: †Trilobita Order: †Agnostida Suborder: †Agnostina Superfamily: †Agnostoidea Family: †Peronopsidae Genus: †Peronopsis-
