Lomasuchus is an extinct genus of peirosaurid notosuchian known from the Late Cretaceous (Santonian stage) of Neuquén Province, western central Argentina. It contains a single species, Lomasuchus palpebrosus. Lomasuchus lends its name to a subfamily of peirosaurids called the Lomasuchinae. Lomasuchinae was constructed in 2004 and included Lomasuchus (the type genus), and a tribe called Mahajangasuchini, which included Mahajangasuchus and Uberabasuchus. Mahajangasuchus is now placed outside Peirosauridae in a different family, Mahajangasuchidae.

| - 洛馬鱷屬（屬名：Lomasuchus）是中真鱷類佩羅鱷科的一屬，生存於白堊紀晚期的南美洲。 洛馬鱷的化石發現於阿根廷內烏肯省的Bajo de la Carpa組地層。地質年代相當於白堊紀晚期，但無法確定實際年代，可能是康尼亞克階或桑托階。 洛馬鱷的口鼻部狹窄、上下高，這些是佩羅鱷科的特徵。牙齒的側向扁平、帶有鋸齒狀邊緣。洛馬鱷的口鼻部狹窄，前上頜骨、上頜骨之間有凹處，當咬合時，下頜的大型牙齒會與上頜凹陷互相咬合；烏貝拉巴鱷也有這些特徵。洛馬鱷、烏貝拉巴鱷的差異在於數個頭部特徵，例如眼眶形狀。 在2004年的佩羅鱷科種系發生學研究，在佩羅鱷科之內建立洛馬鱷亞科（Lomasuchinae）、馬任加鱷族（Mahajangasuchini）。洛馬鱷亞科的模式屬是洛馬鱷，而馬任加鱷族包含馬任加鱷、烏貝拉巴鱷。馬任加鱷目前被歸類於馬任加鱷科。 (zh)

| - Lomasuchus is an extinct genus of peirosaurid notosuchian known from the Late Cretaceous (Santonian stage) of Neuquén Province, western central Argentina. It contains a single species, Lomasuchus palpebrosus. It is known only from the holotype 4084 PV which was found in the Loma de la Lata locality of the Neuquén Province, Patagonia. It was originally reported as collected from sediments of the Rio Colorado Subgroup, Neuquén Group. Later, Hugo and Leanza (2001) noted that this specimen was actually collected from the underlying Portezuelo Formation of the Rio Neuquén Subgroup, Neuquén Group. More recent stratigraphic work on this area identified that horizon as belonging to the younger, Coniacian-age, Plottier Formation of the Rio Neuquén Subgroup. This horizon is currently considered to pertain to the Santonian-age Bajo de la Carpa Formation of the Rio Colorado Subgroup. Lomasuchus had a deep, narrow snout characteristic of peirosaurids. The serrated teeth were compressed, although not to the extent seen in other related genera such as Peirosaurus. Many similarities can be seen between its morphology and that of the related Uberabasuchus, such as the narrow snout and a groove at the maxilla-premaxilla contact that accommodated for an enlarged fourth mandibular tooth. The two genera are distinguished from one another on the basis of several features, including the shape of the orbits. Lomasuchus lends its name to a subfamily of peirosaurids called the Lomasuchinae. Lomasuchinae was constructed in 2004 and included Lomasuchus (the type genus), and a tribe called Mahajangasuchini, which included Mahajangasuchus and Uberabasuchus. Mahajangasuchus is now placed outside Peirosauridae in a different family, Mahajangasuchidae. (en)
