''Cucumericrus decoratus'' is a species of putative
radiodont known from a few poorly preserved specimens.
Only fragments of trunk
cuticle
A cuticle (), or cuticula, is any of a variety of tough but flexible, non-mineral outer coverings of an organism, or parts of an organism, that provide protection. Various types of "cuticle" are non- homologous, differing in their origin, structu ...
and corresponded appendages had been revealed, while important radiodont features such as
frontal appendages are unknown in this species.
The trunk cuticle possess irregular wrinkles
and may had been soft in life.
Each of the trunk appendage compose of a dorsal flap-like element and a ventral stubby leg with unknown distal region,
structurally comparable to the trunk appendages of
gill lobopodians (dorsal flaps and ventral lobopods) and euarthropod biramous appendages (flap-like exopod and limb-like endopod).
The legs have been interpreted as somewhere between annulated
lobopod
The lobopodians, members of the informal group Lobopodia (from the Greek, meaning "blunt feet"), or the formally erected phylum Lobopoda Cavalier-Smith (1998), are panarthropods with stubby legs called lobopods, a term which may also be used as ...
