    Remarks: The fossils described below can be unambiguously referred to the taxon Fluvioviridavis Mayr and Daniels, 2001, with which they share a number of characteristic features, including a long, wide, and dorsoventrally shallow mandible; a coracoid with a deeply excavated, cup-like cotyla...

    Genome of the little bush moa

    Dear Jurek, Well I finally red the Wikipedia article and indeed ancient DNA can be retrieved from some specimen up to a 1.000.000 years old, but that are only fragments of DNA. The article doesn't menmtion birds or colour, nor do the references. Much more research is needed to answer your...

    Genome of the little bush moa

    As far as I know no work through a genome of long extinct birds has been done (by the way, what do you call "long extinct", 500 years or 50.000 years or 150.000,000 years, I would call the first recently extinct with a chance to recover DNA, the second and third long extinct without any sign of...

    Comparative morphology of the avian bony columella

    A tympanic middle ear evolved multiple times among vertebrates as a means to compensate for the impedance mismatch between air and the fluid-filled inner ear (Clack, 2002; Lombard & Bolt, 1979; Tucker, 2017). In birds, this system consists of a tympanic membrane, a cartilaginous extracolumella...
