Profallotaspis is an extinct genus of trilobites. It lived during the early Atdabanian stage, some 520 million years ago.^[1] Profallotaspis jakutensis is arguably the earliest trilobite ever found. Representatives of Profallotaspis have been recorded in the provisional Cambrian Stage 3 deposits of Siberia and, possibly North America.
