Saperion is an extinct genus of trilobite-like arthropod. It lived during the late Atdabanian stage, [1] which lasted from 521 to 514 million years ago during the early part of the Cambrian Period. It was found in the Maotianshan Shales of Yunnan, China. [2] Similar to the closely related Skioldia and Tegopelte , the head shield and trunk tergites were fused into a single plate. There are about 19 furrows indicating the original trunk segments. a small anterior sclerite articulated to the front of its head. [3] A pair of antennae and lateral eyes located ventrally behind the anterior sclerite, lateral to the hypostome. [4] Saperion reached 151 mm in length and had nearly 25 pairs of biramous limbs for walking. [5]
