Tonganoxichnus

[1] The ichnogenus originally included two ichnospecies found in close association.

T. buildexensis is interpreted as the resting trace of a primitive insect, often preserving the outline of the insect's underside in great detail.

T. ottawensis is interpreted as a jumping trace, likely of the same kind of insect, and provides evidence of jumping as an important form of locomotion in the earliest insects.

[1][3] The trace fossils are found in beds typical of the inner freshwater reaches of estuaries but subject to tides.
