A New Genus and Species of Pelagornithidae with Well-Preserved Pseudodentition and Further Avian Remains from the Middle Eocene of the Ukraine

  title={A New Genus and Species of Pelagornithidae with Well-Preserved Pseudodentition and Further Avian Remains from the Middle Eocene of the Ukraine},
  author={Gerald Mayr and Evgenij Zvonok},
ABSTRACT We describe new avian remains from the middle Eocene of eastern Ukraine. The material includes well-preserved bones of a small species of Pelagornithidae (bony-toothed birds), which was tentatively identified as Odontopteryx toliapica in an earlier study. The Ukrainian pelagornithid is, however, distinguished from this species and other early Eocene pelagornithids in several features, and we describe it as Lutetodontopteryx tethyensis, gen. et sp. nov. The new material includes the… 
Diversity of pseudo-toothed birds (Pelagornithidae) from the Eocene of Antarctica
The oldest Antarctic pseudo-toothed bird is reported, represented by an incomplete humerus lacking its proximal end, which comes from the lower Eocene levels of the La Meseta Formation (Seymour Island) and facilitates a review of all known pelagornithids from this continent.
Partial Skeleton of a Bony-Toothed Bird from the Late Oligocene/Early Miocene of Oregon (USA) and the Systematics of Neogene Pelagornithidae
Abstract A partial skeleton of a pelagornithid bird found in latest Oligocene or earliest Miocene marine strata in Oregon consists of a pelvis fragment, thoracic vertebrae, and leg bones of a single
The Earliest Record (Early Miocene) of a Bony-Toothed Bird from South America and a Reexamination of Venezuelan Pelagornithids
ABSTRACT Pelagornithids or bony-toothed birds were an enigmatic group of very large marine birds that existed throughout most of the Tertiary, with remains recovered in all continents. The
The tarsometatarsus of the Middle Eocene loon Colymbiculus udovichenkoi
The previously unknown tarsometatarsus of the earliest unambiguously identified loon, Colymbiculus udovichenkoi, from the Middle Eocene of the Ukraine is described and is considered to be plesiomorphic for Gaviiformes.
Middle Eocene vertebrates from the sabkha of Gueran, Atlantic coastal basin, Saharan Morocco, and their peri-African correlations
Abstract The sabkha of Gueran in the Southwest Moroccan Sahara has yielded a rich and diverse fauna of late middle Eocene vertebrates that include the world's richest Bartonian age archaeocete
Structure and Growth Pattern of Pseudoteeth in Pelagornis mauretanicus (Aves, Odontopterygiformes, Pelagornithidae)
The late maturation of the PelagORNis feeding apparatus, and hence the delayed capability for efficient prey catching, suggests that Pelagornis was altricial, and would add support to the hypothesis of a close phylogenetic relationship between Odontopterygiformes and Anseriformes.
Phylogenetic affinities and taxonomy of the Oligocene Diomedeoididae, and the basal divergences amongst extant procellariiform birds
A comprehensive collection of diomedeoidid fossils from the Rupelian stratotype in Belgium are described, which allows the recognition of previously unknown features of phylogenetic significance and contradicting recent proposals that Oceanitinae (southern storm-petrels) are the earliest diverging crown group Procellariiformes.
Marine vertebrate fauna from the late Eocene Samlat Formation of Ad-Dakhla, southwestern Morocco
Abstract Late Eocene deposits of the Samlat Formation, south of Ad-Dakhla city, southwestern Morocco, have yielded a mixed marine and terrestrial vertebrate fauna. Abundant and diversified
Crocodylian assemblage from the middle Eocene Ikovo locality (Lugansk Province, Ukraine), with a discussion of the fossil record and geographic origins of crocodyliform fauna in the Paleogene of Europe
Abstract The known fossil record of crocodyliforms in Europe during the Paleogene is significantly biased, in that the fauna of Western Europe is far better sampled and understood compared to that of
Middle Eocene vertebrate fauna from the Aridal Formation, Sabkha of Gueran, southwestern Morocco
ABSTRACT In the Sahara Desert of southwestern Morocco, the Aridal Formation of Gueran is known for the world's richest Bartonian archaic whale assemblage, which includes both protocetids and


Bony-toothed birds (Aves: Pelagornithidae) from the Middle Eocene of Belgium
The coracoid distinctly differs from that of extant ‘pelecaniform’ birds, and the plesiomorphic presence of a foramen nervi supracoracoidei as well as the absence of a well-delimited articulation facet for the furcula supports a position outside the Suloidea, the clade to which the Sulidae belong.
Middle Eocene Pelagornithidae and Gaviiformes (Aves) from the Ukrainian Paratethys
The Ukrainian fossils document profound differences between middle Eocene and extant marine avifaunas of Europe, and whereas themiddle Eocene Paratethyan avifauna appears to have been similar to that of the North Sea with regard to pelagornithid diversity, the absence of prophaethontids and relative abundance of Gaviiformes may indicate faunistic differences concerning the remaining seabirds.
Osteology of a New Giant Bony-Toothed Bird from the Miocene of Chile, with a Revision of the Taxonomy of Neogene Pelagornithidae
An exceptionally well-preserved giant species from the late Miocene of the Bahía Inglesa Formation in northern Chile, in which most major limb bones are complete and uncrushed, that is one of the largest known pelagornithids and the three-dimensionally preserved bones allow recognition of many previously unknown osteological features.
Abstract:  The first substantial skull of a very large Paleogene bony-toothed bird (Pelagornithidae) is described from the Lower Eocene London Clay of the Isle of Sheppey in England. The specimen is
A Sternum of a Very Large Bony-Toothed Bird (Pelagornithidae) from the Miocene of Portugal
Abstract The sternum of a very large bony-toothed bird (Pelagornithidae) from the Miocene of Portugal is described. The three-dimensionally preserved specimen is one of the largest sterna of a volant
Pseudotoothed Birds (Aves, Odontopterygiformes) from the Early Tertiary of Morocco
This work provides evidence that Dasornis was widespread in the early Tertiary, as it is currently known from the Lower Paleogene deposits of Morocco, England, and Kazakhstan, and Paleoenvironmental studies show that these marine deposits formed in a tropical climate.
Trionyx ikoviensis sp. nov., a new species of soft-shelled turtles (Trionychidae: Trionychinae), is established based on a partial but well preserved skull, isolated shell bones and cervical
Morphology of the quadrate in the Eocene anseriform Presbyornis and extant galloanserine birds
The quadrate's morphology is inconsistent with the currently accepted anseriform phylogeny that nests Presbyornis within the crown‐group as a close relative of the Anatidae and shares ancestral galloanserine characters with the Megapodiidae, the earliest branch of extant galliforms.
The Struthionidae and Pelagornithidae (Aves: Struthioniformes, Odontopterygiformes) from the late Pliocene of Ahl al Oughlam, Morocco
The Pliocene locality of Ahl al Oughlam is situated at the southeastern limit of the city of Casablanca, in Morocco, on an ancient seashore of the Atlantic Ocean, and has yielded a very rich vertebrate fauna including both terrestrial and marine forms.
