The suture line and constriction are homoeomorphic with some Cenomanian Sciponoceras. Baculites paradoxus (Fig. 38A) is another minute, doubtful baculitid from the Maastrichtian of Draa et Tbaga, Tunisia, described by Pervinquiere (1907: 94, pi. 4 (figs 10-11), text-fig. 24). According to Pervinquiere (1907: 94), this species is unique in allegedly having five saddles and lobes instead of six (around the whole periphery), a feature also noted by Reeside (1927&: 9). An alternative interpretation could be that the internal lobe (I) is merely very small, and as large as the median incisions of the saddles E/L and L/U. The triangular shape of the saddles and lobes is similar to that of Baculites indet., from which it differs by the lack of constrictions. Both are.
