Oestokerkus

Oestokerkus is an extinct genus of Cambrian megacheiran arthropod known from the Emu Bay Shale of Kangaroo Island, Australia.

The great appendages have long flagellae projecting from them.

The head shield probably had two pairs of cephalic appendages.

The exopods of the biramous limbs are fringed with long setae.

[1] The body ended with a telson, which was probably dorsally flattened.
