[3] Detailed morphology of the frontal appendages and oral cone are equivocal due to the limited preservation, but the former represent typical hurdiid features (e.g. subequal blade-like endites).

[6] The preserved contents of its digestive tract are similar to those of other predatory arthropods,[8] and this lifestyle is supported by the raptorial nature of the spiny frontal appendages and the size of the eyes.

[1][2] This underlined the utility of lagerstätten like the Hunsrück Slate, as the exceptionally preserved fossil horizons may be the only available opportunity to observe non-mineralised forms.

One classification scheme has Schinderhannes sister to the euarthropods (crown or 'true' arthropods) instead of other radiodonts, based on the characters which interpreted to be euarthropod-like (e.g. sclerotized tergite, biramous appendage).

[3] However, this scenario had been challenged by later investigations, as the putative euarthropod-like features were questioned to be rather radiodont-like characters (e.g. soft trunk cuticle, setal blades and paired flap muscles).

[2] In 2023, Potin and Daley considered its placement within Hurdiidae doubtful due to the huge gap in time between the latest definitive radiodonts from the Early Ordovician.
