DESCRIPTION ħe specimen is a diamond-shaped, 1.7 mm long tessera with a single central, narrow, elongate tubercle ( c. 1.4 mm long). ħis tubercle has denticulated edges. Each denticulation is simple (undivided). Additionally, on each side of this central tubercle occurs a much smaller narrow tubercle (Fig. 6D). ħe base of the tessera is perforated by small foramina of the underlying (probably reticulated) layer. ħis tessera compares well with those of Lepidaspis serrata Dineley & Loeffler (1976: figs 74, 76, pl. 32: 6, 7), and especially with the tessera in their plate 32: 6, which bears a small lateral tubercle beside the main central denticulated one.
