This animal paper model is a Wiwaxia, a genus of soft-bodied, scale-covered animals known from Burgess shale type Lagerstätte dating from the upper Lower Cambrian to Middle Cambrian, the paper model designed by zardoz.
The organisms are mainly known from dispersed sclerites; articulated specimens, where found, range from 3.4 millimetres (0.13 in) to a little over 50.8 millimeters (2 in) in length. They bear a set of mouthparts comprising two to three identical rows of rasping teeth that lay on a supporting apparatus or "tongue"; this feeding arrangement seems to represent a 'prototype' molluscan radula.
