Nettapezoura is known only by one
specimen, UU 04083.02, which preserved the body in a parallel oblique angle, revealing more of its left dorsolateral side. The body comprise of a cephalon (head) and an 11-segmented trunk. All of the dorsal
exoskeletons (
tergites) does not have any well-defined boundaries between the axial region (vaulted middle section) and tergopleurae (lateral extensions). The cephalon is covered by a semicircular shield. The first 8 trunk segments are wide and possess triangular tergopleurae. The last 3 trunk segments are narrow and tube-like.
Telson (tail) widen posteriorly and trifurcated into 3 short spines, resembling the
webbed foot of a duck and hence the name
Nettapezoura ("duck foot tail"). Evidence of
appendages are scarce. There are at least 2 pairs of thin, long appendages exposed from the cephalic shield. These were originally thought to be
endopods (inner/lower branch), but subsequently identified as
exopods (outer/upper branch) like those of
habeliids and
Megachelicerax. The trunk have at least 7, possibly 8 pairs of flap-like appendages, each possess an outer rami fringed by lamellae and an inner rami with leaf-like lobations. The last 3 trunk segments have no appendages. == Classification ==
