Quick Facts Scientific classification, Type species ...

Dartmuthia is one of the only osteostracans in which material of the trunk and tail behind the armored head shield have been found. Since the mouth is positioned on the underside of the head Dartmuthia is presumed to have dwelled on the ocean floor, sucking its food into its mouth.[3]
