Entothyreos is a genus of extinct panarthropod belonging to the group Lobopodia and known from the middle Cambrian Burgess Shale in British Columbia, Canada. The genus contains a single species, Entothyreos synnaustrus (meaning "convergent inner shield"), described in 2024.[1] Entothyreos is significant for possessing a remarkable degree of sclerotization among lobopodians, comparable to that of arthropods.
