One of these groups, called Lirainosaurinae, is relatively known in the Iberian region and is characterized by small and medium-sized species, which evolved in an island ecosystem.<\/p>\n \u201cIn other words, Europe was a huge archipelago made up of several islands during the Late Cretaceous. However, Qunkasaura belongs to another group of sauropods, represented in the Iberian Peninsula by medium-large species 73 million years ago.<\/p>\n Restoration process of part of the remains of Qunkasaura.

Their unique morphology, especially in the tail vertebrae, offers new insights into the non-avian dinosaurs of the Iberian Peninsula, a historically poorly understood group.<\/p>\n<\/div>\n Bone remains of Qunkasaura pintiquiniestra, on display in the Paleontological Museum of Castilla-La Mancha.

Lohuecosaurs may have originated on the southern continents (Gondwana) before dispersing globally.<\/p>\n The name Qunkasaura pintiquiniestra is made up of several geographic and cultural references close to the Lo Hueco site. \u201cQunka\u201d refers to the oldest etymology of the toponym from the Cuenca and Fuentes area, \u201cSaura\u201d alludes to the feminine of the Latin saurus (lizard), but also pays homage to the painter Antonio Saura, and \u201cpintiquiniestra\u201d refers to the giant \u201cQueen Pintiquiniestra,\u201d character from a novel mentioned in \u201cDon Quijote de la Mancha\u2019 by Cervantes.<\/p>\n Relationships of Qunkasaura with some of the most important sauropods from the Late Cretaceous and reconstruction of the life form of Qunkasaura pintiquiniestra..

Part of the skeleton of Qunkasaura is already on display in the Paleontological Museum of Castilla-La Mancha in Cuenca (Spain).<\/p>\n Paper:<\/p>\n Mocho, P, A Spanish saltasauroid titanosaur reveals Europe as a melting pot of endemic and immigrant sauropods in the Late Cretaceous,\u00a0Communications Biology\u00a0(2024).\u00a0DOI: 10.1038\/s42003-024-06653-0<\/a><\/em><\/p>\n Written by Eddie Gonzales\u00a0 Jr. \u2013 AncientPages.com – MessageToEagle.com Staff Writer<\/strong><\/p>\n \n\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n![\"Qunkasaura:](\"https:\/\/www.ancientpages.com\/wp-content\/uploads\/2024\/09\/newsauropodiberiasep5.jpg\")
