Vachonisia

Vachonisia is a Devonian marrellomorph known from the Lower Devonian Hunsrück Shale.[1] It grows in a similar fashion to the other Hunsruck marrellomorph, Mimetaster,[2] and is closely related to the Silurian Xylokorys.[3] It is known from 20 specimens; its whole body is covered by a shield-like carapace.[3]
