Platycrossos is an extinct genus of protocoleopteran beetles in the family Permosynidae. It is known from the Triassic and Jurassic of Australia, Austria, Mongolia and Russia. Like other members of the family, the species of this genus were described from fossils of isolated elytra with punctate striae.[2][3]
