Localities: Fumanya, Molí del Baró-1, Les Torres-2, L’Espinau, Els Nerets (L2).
Material: MCD-5557–59, IPS-96650, IPS-96708–10, IPS-90162, IPS-90182, IPS-105942, IPS-105949, IPS-105951, IPS-105953 ( Fig. 5A–C View Figure 5 ).
Description: Relatively wide and blunt teeth, with the labial surface more convex than the lingual surface. The complete teeth are 4.9‒29.9 mm high basiapically and 4.6‒12.5 mm wide mesiodistally. The cross-section is D-shaped due to the carinae, which are placed lingually to the mesiodistal plane. The mesial and distal carinae are well developed, emphasized by two well-marked longitudinal grooves in the lingual side. The enamel has numerous, short and fine ridges in both labial and lingual faces. The ridges are not parallel and develop false-ziphodont crenulations at the contact with the carinae ( Fig. 5A–C View Figure 5 ).
Remarks: Although ‘corrugated margins’ were described in Musturzabalsuchus ( Buscalioni et al., 1997, 1999), several differences were identified after direct comparisons with the material from Laño. Teeth of Musturzabalsuchus are triangular in outline, labiolingually compressed and more pointed, carinae are less developed and placed in line with the mesiodistal plane, and the ornamentation of the enamel is smoother than in A.palustris .These conditions do not change along the toothrow, as observed in Musturzabalsuchus bones bearing complete, or almost complete, dental series (personal observation). Concerning allodaposuchids, Allodaposuchus palustris is the only species with this ornamentation pattern and false-ziphodont dentition ( Blanco et al., 2014; Blanco & Brochu, 2017). No other crocodyliform with similar ornamentation has been described in the Tremp Formation. This morphotype corresponds to morphotype 4 described by Marmi et al. (2016) from the Molí del Baró-1 site.
