[1] The muscle fibres preserved in its legs establish peripheral musculature as a characteristic of all panarthropods, but are arranged in an unusual pattern (detailed below).

This was 1 millimeter long, and folded at the mid-point, with one pair of lobopods preserved and much of the dorsal body surface missing.

Along the two lobopods, the wrinkles become smaller and eventually give way to raised polygonal boundaries, which could mark cell borders in the skin tissue.

The lobopods had a circular cross-section, flattened in places, and are thought to be at the posterior end of the specimen with the claws pointing towards the anterior, as in other lobopodians.

In living onchyophorans, the outermost layer of muscle is circular, the middle interwoven oblique and the innermost longitudinal, reversing the order of those in Tritonychus.

This extends the record of these features into the lower Cambrian, along with the multiple layers of peripheral muscle and the possible gonopore.
