Vladicaris is an arthropod known from the Lower Cambrian Paseky Shale member, Czech Republic, where it occurs alongside other arthropods, namely Kodymirus vagans and Kockurus grandis. It has been attributed to the Crustacean, and if it does indeed belong in the crown group of that subphylum, it would be the earliest known representative of the group.[

The organism has a segmented trunk and an elongate carapace – characters which have led to suggestions that it should be allied to the Pectocaris.
