Nereites (trace fossil) pugnus Emmons, 1844

Taksoni kirjeldused

Pazos et al., 2015bb

Description:Nereites with an external width of 0.9–1.5 cm and preserved length of 6 cm. The overall morphology resembles branches and is preserved as endichnial traces with narrow median tunnels. The lobes are elongated, arranged and inserted at an acute angle with respect to the middle tunnel; these are individually arcuate, with a sharp line that gives them a leaf-like appearance. The burrow is short and two of the specimens recorded in the same slab are very similar; a partial juxtaposition of lobes is present. A third specimen shows a median tunnel but no clear lobes; it resembles in part the pustules observed in N. cambrensis. On the same surface, very short and thin burrows resembling undermat mining trace fossils are sparsely recorded.
