摘要:The “Futalognko” site, situated at the margins of the Los Barreales lake about 90 km northwest
of Neuquén city (Patagonia), revealed several new dinosaur specimens, all from the Portezuelo Formation
(Turonian-Early Coniacian). Among those are the remains of new theropod dinosaur referable to a new
species of the maniraptoran Unenlagia, Unenlagia paynemili n. sp. The material is represented by a pubis,
humerus, ilium, and a dorsal vertebra, plus a pedal phalanx and a claw that tentatively referred to this new
species. It shares with Unenlagia comahuensis a posteriorly oriented distal end of the pubis that shows a
convex anterior margin and differs by possessing more gracile bones, angle between the anterior rim of the
deltopectoral crest and the humerus shaft more closed, the presence of a small anterior process on the
distal end of pubis, and the distal end of the postacetabular blade of ilium broader and rounded, with a
shallower brevis fossa
