Eurolimnornis
''Eurolimnornis'' is the name given to a monotypic genus of pterosaurs from the Early Cretaceous. The only known species ''E. corneti'' probably was originally identified as a primitive but essentially modern bird (or even as an early neognathe ancestral to the grebes),〔Kessler, E. & Jurcsák, T. (1986): New contributions to the knowledge of the Lower Cretaceous bird remains from Cornet (Romania). ''Travaux du Musée d'Histoire Naturelle Grigore Antipa'' 28: 289–295.〕 although alternative theories later suggested that it was a non-avialan theropod or pterosaur.〔Benton, M. J.; Cook, E.; Grigorescu, D.; Popa, E. & Tallódi, E. (1997): Dinosaurs and other tetrapods in an Early Cretaceous bauxite-filled fissure, northwestern Romania. ''Palaeogeography, Palaeoclimatology, Palaeoecology'' 130: 275-292. (PDF fulltext )〕 The identification as a pterosaur was supported by a re-evaluation of the fossil remains published in 2012.
The holotype and only material known to date (MTCO-P 7896) is a distal fragment of the right humerus, which was at first ascribed to the same species as the specimen of ''Palaeocursornis corneti'', a possible synonym also originally identified as a bird.〔Bock, Walter J. & Bühler, Paul (1996): Nomenclature of Cretaceous birds from Romania. ''Cretaceous Research'' 17: 509–514. (PDF fulltext )〕〔
The remains were found in Berriasian (around 143 mya) deposits at Cornet near Oradea, Romania. ''Eurolimnornis'' occurred on what was then an archipelago of volcanic and coral islands towards the east of the Piemont-Liguria Ocean. Its habitat was hilly, karstic terrain with numerous freshwater and/or brackish rivers, lakes and swamps. As this archipelago lay around 35°N latitude in a warmer, wetter climate than exists today, it was roughly similar to today's Caribbean or Indonesia.(Benton ''et al.'', 1997)
