ABSTRACT The fossil record of post-Paleozoic lungfishes in Greenland is currently restricted to a few brief reports of isolated and undetermined tooth plates coming from the uppermost Fleming Fjord Formation (late Norian) in Jameson Land, central East Greenland. Here, we describe Ceratodus tunuensis, sp. nov., a new dipnoan from a thin bed of calcareous lake mudstone from the Ørsted Dal Member of the Fleming Fjord Formation. The Ceratodus fossil record indicates that during the Late Triassic… 
A record of new lungfishes (Osteichthyes: Dipnoi) from the Carnian (Upper Triassic) of India
ABSTRACT Numerous tooth plates of different types were recovered from the Upper Triassic Tiki Formation of India. Sharp crested tooth plates with five acute ridges, tubercles on the crests, robust
A New Species of Fossil Lungfish (Osteichthyes: Dipnoi) from the Cretaceous of Australia
ABSTRACT Lungfish tooth plates have been known from Cretaceous deposits at Lightning Ridge and nearby opal fields since 1914. These specimens are reasonably complete, and assigned to a common
Dipnoan from the Upper Triassic of East Greenland and remarks about palaeobiogeography of Ptychoceratodus
Here we present a description of the dipnoan remains collected from the middle to upper Norian (Upper Triassic) of Jameson Land, East Greenland. The specimens consist of isolated tooth plates and s
Issi saaneq gen. et sp. nov.—A New Sauropodomorph Dinosaur from the Late Triassic (Norian) of Jameson Land, Central East Greenland
The Late Triassic (Norian) outcrops of the Malmros Klint Formation, Jameson Land (Greenland) have yielded numerous specimens of non-sauropod sauropodomorphs. Relevant fossils were briefly reported in
Triassic lithostratigraphy of the Jameson Land Basin (central East Greenland), with emphasis on the new Fleming Fjord Group
The lithostratigraphy of the Triassic deposits of the Jameson Land Basin in central East Greenland is revised. The new Scoresby Land Supergroup is now composed of the Wordie Creek, Pingo Dal,
Middle–Late Triassic evolution of the Jameson Land Basin, East Greenland
Abstract The Jameson Land Basin lies within the Greenland–Norway rift, to the south of Triassic basins on the Halten Bank and East Greenland shelf, and can therefore offer insights into the


Ceratodus diutinus, a New Ceratodont from Cretaceous and Late Oligocene-Medial Miocene Deposits in Australia
Ceratodus diutinus , a new species of ceratodont lungfish similar to but not identical with Ceratodus kaupi Agassiz, 1838–1844, is described from the Lower Cretaceous Griman Creek Formation at Grawan
New Species of Lungfish (Sarcopterygii, Dipnoi) from the Late Triassic Krasiejów Site in Poland, with Remarks on the Ontogeny of Triassic Dipnoan Tooth Plates
A new species of lungfish is described based on 25 tooth plates from the Upper Triassic (Carnian) freshwater sediments of the Krasiejów locality, in Poland, which is most closely related to P. concinnus from the Lehrberg Beds in Germany.
A new genus for the Dipnoan species Ceratodus tuberculatus Tabaste, 1963
A tooth plate of the large lungfish referred to Ceratodus tuberculatus Tabaste, 1963 from Kharga Oasis, Egypt, allows reconsideration of its generic status. Comparisons with fossil Ceratodus and
A Review of Cretaceous dipnoans from Argentina (Sarcopterygii Dipnoi) with Descriptions of New Species
The oldest dipnoan record from Argentina is reported, coming from the Cenomanian of Northwestern Patagonia, Rio Negro province, and it is proposed that the genus †Metaceratodus is more closely related to Neoceratodus than either is to †Cerat Exodus or †Ptychocer atodus, supporting prior hypotheses.
A new Thai Mesozoic lungfish (Sarcopterygii, Dipnoi) with an insight into post‐Palaeozoic dipnoan evolution
A new species of lungfish is described, Ferganoceratodus martini sp.
A new species of the genus Atlantoceratodus (Dipnoiformes: Ceratodontoidei) from the Uppermost Cretaceous of Patagonia and a brief overview of fossil dipnoans from the Cretaceous and Paleogene of South America
A new phylogenetic analysis including tooth plates and calvarian morphology has been conducted in order to evaluate the relationships among post-Paleozoic dipnoans of the clade Ceratodontoidei.
Metaceratodus kaopen comb. nov. and M. wichmanni comb. nov., two Late Cretaceous South American species of an austral lungfish genus (Dipnoi)
The occurrence of Metaceratodus in southern South America corroborates a close biogeographical relationship with Australia in the latest Cretaceous and reassigns three putative species to Metacer atodus under two new combinations: M. kaopen comb.

ABSTRACT The ceratodont lungfish Metaceratodus wollastoni is described from new material from central and southern Australia, and three additional species, Metaceratodus ellioti, Metaceratodus bonei,
The vertebrate-bearing Late Triassic Fleming Fjord Formation of central East Greenland revisited: stratigraphy, palaeoclimate and new palaeontological data
Abstract In Late Triassic (Norian–Rhaetian) times, the Jameson Land Basin lay at 40° N on the northern part of the supercontinent Pangaea. This position placed the basin in a transition zone between
A new species of Protopterus and a revision of Ceratodus humei (Dipnoi: Ceratodontiformes) from the Late Cretaceous Mut Formation of eastern Dakhleh Oasis, Western Desert of Egypt
Three lungfish species are recognized from tooth plates recovered from shales of the Mut Formation (Qusseir Group) in eastern Dakhleh Oasis, and it is demonstrated that many tooth plates assigned to this species subsequent to its original description do not belong within C. humei.
