Taxonomic remark From Brookfield, 2024: Dictyocaris slimoni, forms large carbonaceous sheets up to 30 cm in diameter, commonly pierced by variably sized circular holes up to 5 mm across, with raised rims (Figure 9). Dictyocaris specimens were originally thought to be fragments of large arthropod carapaces, with the holes as parasitic injuries from Jamoytius mouths. Dictyocaris is, however, never found even partially articulated, despite its association with articulated Ceratiocaris specimens which have no similar holes. And the large number of holes on the illustrated specimen also seems too many to be the results of parasitism, considering the size of Jamoytius (14–18 cm). Dictyocaris thus is likely a plant.
