Sulculites bellus Vialov and Nessov, 1974

( Figure 4G View FIGURE 4 )

Material. Many narrow grooves on three carapace remains (NVP027‒029).

Description. Smooth, slender, narrow, non-branched straight to curved grooves in the surface of bones. They occur solitarily or in clusters, sometimes crossing each other. Width ranges from 0.25–0.6 mm

Discussion. The specimens described show most of the morphological characters of the holotype of S. bellus as described and illustrated by Vialov and Nessov (1974, p. 101, figures 1‒4).

Producer. Sulculites most likely belongs to the category fodinichnia (Zonneveld, personal comm.). According to Vialov and Nessov (1974), worms are suggested to be the main producer of this trace fossil.

Stratigraphic and geographic distribution. Campanian of the Qarn Ganah, Kharga Oasis (this study). Sulculites bellus is firstly recorded from the Albian of Eastern Uzbekistan ( Vialov and Nessov, 1974). This determination extends the stratigraphic range of the taxon up into the Campanian.

Ichnogenus Machichnus Mikuláš et al.,2006

Type ichnospecies. Machichnus regularis Mikuláš et al., 2006

Diagnosis. Shallow serial parallel or subparallel grooves in turtle bone. The groove surface is smooth or longitudinally striated. Each series consists usually of dozens of grooves, which are typically uniform in shape and dimensions. The grooves are oriented perpendicular to substrate edge ( Mikuláš et al., 2006).
