Andrzej Elżanowski
Andrzej Elżanowski (born 21 January 1950) is a Polish paleontologist and vertebrate zoologist specializing in bird phylogeny. Together with Peter Wellnhofer he described a coelurosaur theropod "Archaeornithoides" in 1992. He works also on Mesozoic birds, especially Archaeopterygiformes – he is author of the chapter "Archaeopterygidae" in book edited by Luis Chiappe and Lawrence Witmer entitled "Mesozoic Birds: Above the Heads of Dinosaurs". In 2001 he determined that Solnhofen specimen of "Archaeopteryx" represents new species and genus and coined new specific name – "Wellnhoferia grandis" – for it. He works now in the Faculty of „Artes Liberales” at the University of Warsaw
