The revised avian fauna of Rudabànya (Hungary, Late Miocene)

Contribuciones del Museo Argentino de Ciencias Naturalis “Bernardino Rivadavia” 7: 253-266

Again one of the papers of the 9th SAPE meeting in Argentina, 2016.
Paleontología y Evolución de las Aves


A revision of the avian fauna from the Rudabànya locality (Hungary, late Miocene) is presented. This is one of the few avian faunas dated to the earliest part of the late Miocene (MN 9), and thus is of major importance for understanding the evolution of birds during the Miocene. The current revision confirms the presence of at least 13 taxa, but only three of them can be identified to genus level because of the fragmentary nature of the material. Waterfowls (Anatidae) are represented by three taxa, including possible species of Mioquerquedula. Galliform birds are especially diverse (five taxa). Members of the subfamily Rollulinae are for the first time identified from Europe. Unidentified representatives of Ralliformes and Strigidae are also present. A small passerifom bird, previously described as Certhia janossyi Kessler & Hir, 2012, is characterized by a coracoid with an unusual morphology. This taxon is transferred here to a new genus within the superfamily Sylvioidea. Several other indeterminate passerines are present. The previously identified genera Anas, Palaeortyx, Miorallus, Tringa, Merops, Intulula (Strix), and Sturnus cannot be confirmed. In general, the fauna has a rather archaic composition and shows affinities with the middle Miocene European avian assemblages.

Remarks by me:

Beside many more revisions mentioned above Nikita Zelenkov describes in this paper a new genus: Sylvosimadaravis nov. gen. the type species is Certhia janossyi Kessler & Hir, 2012 and places Sylvosimadaravis janossyi (Kessler et Hïr, 2012) in the superfamily Sylvioidea.

Unfortunately, the proceedings are not (yet?) on line.

For the Original description of Certhia janossyi Kessler et Hïr, 2012 see:


Észak-Magyarország madárvilága a miocénben II. rész
The avifauna in North Hungary during the Miocene Part II

Földtani Közlöny 142/2 (2012): 149-168


In this paper the authors present details about avian remains found at Miocene sites in North Hungary. These remains are those of Passeriformes and up until now they have not received much attention.
The recently identified remains which are examined in the present paper include: 1 order, 13 families, 19 genera (three of which are now extinct), and 16 extinct species. From these, one genus and 16 species represent new taxa to the science. Four taxa could be identified only to the level of order (1), and genus (3). The genera and species which are completely new to the science are presented below. The aforementioned, recently identified new fossil genera and species have been described according to the following characteristics (for the abbrevations see the chapter entitled “Rövidítések”):

New taxa:

Galerida cserhatensis n. sp.
Lullula neogradensis n. sp.
Praealauda n. gen.: Praealauda hevesensis n. sp.
Anthus antecedens n. sp.
Cinclus major n. sp.
Fam. Turdidae RAFINESQUE, 1815: Turdicus KRETZOI, 1962: Turdicus minor n. sp.
Muscicapa leganyii n. sp.
Erithacus horusitzkyi n. sp.
Luscinia praeluscinia n. sp.
Certhia janossyi n. sp.
Phylloscopus miocaenicus n. sp.
Lanius schreteri n. sp.
Bombycilla hamori n. sp.
Sturnus kretzoii n. sp.
Emberiza bartkoi n. sp.
