Minqaria bata

Reptilia - Hadrosauridae

Taxonomy
Minqaria bata was named by Longrich et al. (2024) [Longrich et al. (2024): "MHNM.KHG.1395 (Museum d'Histoire Naturelle de Marrakech, Marrakech, Morocco, Cadi Ayyad University), right maxilla with teeth, left dentary, and braincase (Figs. 3, 4, 5, 6 and 7). The remains found in association by locals working the mines; color and preservation of the bone and associated matrix, size, and lack of duplication of elements are consistent with an associated individual."]. Its type specimen is MHNM.KHG.1395, a partial skull, and it is a 3D body fossil. Its type locality is Sidi Chennane [upper Couche III] (general), which is in a Maastrichtian marine phosphorite in the Couche III Formation of Morocco. It is the type species of Minqaria.

Diagnosis
ReferenceDiagnosis
N. Longrich et al. 2024Small lambeosaurine characterized by the following character combination, which also differentiates it (where the specimens overlap) from Ajnabia odysseus. Jugal articulation lies very low on maxilla (autapomorphic within lambeosaurinae); ectopterygoid ridge ends at jugal articulation. Ectopterygoid ridge concave in lateral and dorsal views, narrower posteriorly than anteriorly. Neurovascular foramina arranged in a row. Highly domed frontoparietal, with extensive contribution of parietal to the dome, and a triangular parietal table. Maxillary toothrow sinusoidal in lateral or ventral views, with a deep buccal fossa. Dentary short and deep, occlusal margin straight; symphyseal process strongly extended anteriorly, and with straight ventral margin. Alveolar ridges of maxilla and dentary poorly developed. Teeth small, with narrow apices, broad central ridges, and rugose enamel.
