A diverse microvertebrate fauna is described from the Virgin Hills and Napier formations, Bugle Gap Limestone Canning Basin, Western Australia. Measured sections at Horse Spring and Casey Falls (Virgin Hills Formation) and South Oscar Range (Napier Formation) comprise proximal to distal slope carbonates ranging in age from the Late Devonian Frasnian to middle Famennian. A total of 18 chondrichthyan taxa are identified based on teeth, including the first record of Thrinacodus tranquillus, Cladoides wildungensis, Protacrodus serra and Lissodus lusavorichi from the Canning Basin. A new species, Diademodus dominicus sp. nov. is also described and provides the first record of this genus outside of Laurussia. In addition, the upper range of Australolepis seddoni has been extended to Late Devonian conodont Zone 11, making it the youngest known occurrence for this species. The Virgin Hills and Napier formations microvertebrate faunas show close affinities to faunas recovered from other areas of Gondwana, including eastern Australia, Iran, Morocco and South China, which is consistent with known conodont and trilobite faunas of the same age.

“…Cúspides alongadas também são comuns nos gêneros paleozóicos Akmonistion, Saivodus, Stethacanthus e Cladoselache (Coates & Sequeira, 2001, Duffin & Ginter, 2006, porém estes gêneros diferem na base, com projeções basolabiais e ornamentações, na presença de cúspides secundárias (ou acessórias), na ornamentação da projeção lingual e presença de botões ou saliências.…”

“…O fóssil foi encontrado associado a braquiópodes, cefalópodes, gastrópodes e bivalves indicando ambiente deposicional marinho. Silva Santos (1967) o comparou a vários gêneros que possuem dentição tipo cladodonte como Cladodus, Denaea, Symmorium, Ctenacanthus e Goodrichia concluindo que o fóssil apresentava maior semelhança com dentes atribuídos a Cladodus do Carbonífero da Grã Bretanha e Estados Unidos, como C. gomphoides, C. intercostatus (= C. elegans para Duffin & Ginter, 2006) e C. bellifer, atribuindo-o, portanto, ao gênero Cladodus. A partir das revisões de dentes cladodontes de Ginter et al (2005) e Duffin & Ginter (2006) "Cladodus" parauariensis pode ser comparável não a Cladodus, mas a Glikmanius, devido a presença do botão preservado na região orolingual e pelas protuberâncias basolabiais.…”

ResumoDentes tipo cladodonte são conhecidos desde o século XIX. Após uma breve revisão das ocorrências de dentes cladodontes da America do Sul, todas do Neopaleozóico, são descritos três espécimes, provenientes de um afloramento de arenito conglomerático do Membro Taquaral, unidade inferior da Formação Irati (Cisuraliano). O referido arenito conglomerático aflora na região centroleste do Estado de São Paulo, próximo a borda leste da Bacia do Paraná. O primeiro dente é semelhante a "Cladodus" parauariensis do Neocarbonífero da Bacia do Amazonas e a espécies do gênero Glikmanius devido a depressão basolabial profunda. A segunda é similar a espécimes do Pensilvaniano, Formação Lecompton de Nebraska pelo formato da base e da única cúspide e a terceira tem a coroa como de Glikmanius occidentalis e a espécies de Cladodus.Palavras-chave: Chondrichthyes, Irati Formation, cladodontes, Permiano Abstract Cladodont-type teeth are known since the XIX century. After a brief review of the cladodonts teeth occurrences from South America, all from the late Paleozoic, three specimens are here described. They come from a conglomeratic sandstone outcrop of the Taquaral Member, the lower unit of the Irati Formation (Cisuralian). This conglomeratic sandstone is located at the center-east State of São Paulo, Brazil, near the eastern border of the Paraná Basin. One tooth is similar to "Cladodus" parauariensis from the Pennsylvanian of the Amazonas Basin, Brazil, and species of Glikmanius due to of the presence of deep basolabial depression. The second tooth is similar to specimens of the Pennsylvanian Locompton Formation from Nebraska, based on the shape of its base and the presence of a cusp. The third tooth has a crown, like Glikmanius occidentalis, and some species of Cladodus.

“…The most similar teeth of the genus Lissodus appear to be those of L. nodosus from the Anisian to Norian of Germany and Poland (Seilacher 1943;Duffin 1985Duffin , 2001. Among the similarities of the above-listed features the very weak labial peg (on the posterodorsal teeth of L. nodosus) and the ridged and ornamented labial side are of great importance.…”

Remains of Triassic vertebrates discovered in the Villány Hills (SW Hungary) are described here. After the well-documented Late Cretaceous Iharkút locality, this material represents the second systematically collected assemblage of Mesozoic vertebrates from Hungary. Fossils were collected from both the classical abandoned road-cut at Templom Hill (Templom-hegy) and a newly discovered site at a construction zone located 200 meters west of the road-cut. Macrofossils of the construction site are mainly isolated bones and teeth of nothosaurs from the Templomhegy Dolomite, including a fragmentary mandible referred to as Nothosaurus sp. and placodont teeth tentatively assigned here to cf. Cyamodus sp. Affinities of these fossils suggest a Middle Triassic (Ladinian) age of these shallow marine deposits.New palynological data prove for the first time a Late Triassic (Carnian) age of the lower part of the Mészhegy Sandstone Formation. Vertebrate remains discovered in this formation clearly represent a typical Late Triassic shallow-marine fauna including both chondrichthyan (Lissodus, Palaeobates, Hybodus) and osteichthyan (cf. Saurichthys, ?Sphaerodus sp.) fish fossils. The presence of reworked nothosaur and placodont tooth fragments as well as of possible archosauriform teeth, suggest an increase of terrestrial influence and the erosion of underlying Triassic deposits during the Late Triassic.A belemnite rostrum collected from the lowermost beds of the Somssichhegy Limestone Formation proves that this Lower Jurassic (Pliensbachian) layer was deposited in a marine environment. Most of the vertebrate remains (nothosaurs, placodonts, hybodont shark teeth, perhaps Palaeobates, Lissodus) recovered from these beds are also reworked Triassic elements strongly supporting an erosive, nearshore depositional environment.
