Material: MCD- 5547–50, MCD- 6850, MCD- 6853, IPS- 96634, IPS- 96678, IPS- 96693, MCD- 4909, IPS-105943, MPZ- 2017/1135, MPZ- 2017/1134, MPZ- 2017– 807 ( Fig. 5G–M View Figure 5 ).
Description: Conical and pointed teeth with high crowns lacking a basal constriction. They are 0.9‒40.4 mm high basiapically and 0.5‒12.5 mm wide mesiodistally. The crowns are subcircular in cross-section, more convex labially than lingually – or even with a lemon-like outline when the carinae are conspicuous ( Fig. 5L–M View Figure 5 ) – slightly labiolingually compressed and lingually bent. The enamel is smooth. Faint anterior and posterior carinae are present, but lack denticles ( Fig. 5 View Figure 5 AE – AG).
Remarks: This morphology is typical of crocodylomorphs with generalist habits. Thus, it is difficult to assign confidently to any particular taxon. However, the most reliable taxonomic referral would be to members of Allodaposuchidae due to the presence of several species in the Tremp Formation ( Puértolas et al., 2011; Blanco et al., 2014, 2015a; Puértolas-Pascual et al., 2014). These features have been observed in teeth belonging to Allodaposuchus hulki and A. subjuniperus . However, teeth preserved in the holotype of the latter species are less acute than those of A.hulki and have two longitudinal lingual grooves next to the carinae, but variation related to the tooth row position cannot be discarded. Morphotype XI differs from teeth of A. precedens , which show enamel ornamented with basiapical ridges, and from the false-ziphodont teeth of A. palustris ( Delfino et al., 2008a; Blanco et al., 2014; Blanco & Brochu, 2017). This morphotype corresponds to morphotype 1 described by Marmi et al. (2016) from the Molí del Baró-1 site.
