Andrzej Elżanowski (born January 21, 1950) is a Polish paleontologist and vertebrate zoologist specializing in bird phylogeny. Together with Peter Wellnhofer he described a coelurosaur theropod Archaeornithoides in 1992.[1] 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.[2] In 2001 he determined that Solnhofen specimen of Archaeopteryx represents new species and genus and coined new specific name – Wellnhoferia grandis – for it.[3] He works now in the Institute of Zoology of the University of Wrocław.[4]
