Lirainosaurinae is asubfamily of lithostrotiantitanosaursauropods from theLate Cretaceous ofFrance,Spain, andRomania.
Lirainosaurinae was defined by Díez Díazet al. (2018) as comprising "Lirainosaurus,Ampelosaurus, their common ancestor, and all of its descendants", and includes the two definitional taxa as well asAtsinganosaurus,Lohuecotitan, andPaludititan. The five genera are known fromEurope and all within the timespan of the lateCampanian (Lirainosaurus) to earlyMaastrichtian (Ampelosaurus andAtsinganosaurus). Lirainosaurinae was recovered by Diezet al. (2018) as phylogenetically intermediate between the clades traditionally consideredSaltasauridae and a clade containing taxa normally found inAeolosaurini andLognkosauria.[1] Unpublished cladistic results by Mochoet al. (2019) recoverLohuecotitan andPaludititan as members of Lirainosaurinae, and place Lirainosaurinae as an early-diverging branch of Saltasauridae.[4]
