“…These observations suggest that phyllolepids and their associated faunas could be found in much older strata within East Gondwana, where poorly-known Early to Middle Devonian assemblages contain highly endemic taxa within the socalled Wuttagoonaspis fauna (Young and Goujet, 2003). Further refinement of existing biostratigraphic schemes using placoderms like Phyllolepis and associated taxa will benefit from further collecting and faunal descriptions in less well known regions such as South America (Young and Moody, 2002) and Africa (Long et al, 1997).…”

“…Devido às grandes proporções do espinho em questão, poderia ser o maior representante conhecido deste gênero. Espinhos de Antarctilamnideos já foram reportados na América do Sul por diversos autores (Gagnier et al, 1988;Janvier & Villarroel, 1998;Young & Moody, 2002), sendo bastante provável que também ocorressem no Brasil. Antarctilamna seriponensis da Bolívia (Gagnier et al, 1988), posteriormente considerada apenas como um antarctilamnideo por Ginter et al, (2010) e Antarctilamna ultima da África do Sul (Gess & Coates, 2015) possuem espinhos com formato triangular em vista lateral, característica também encontrada no espécime aqui descrito, diferindo consideravelmente dos espécimes de pequeno porte da espécie-tipo A. prisca descritos por Young (1982).…”

“…Entretanto, no registro boliviano, são encontrados restos de Placodermi, mesmo que raros, em contraste com os afloramentos brasileiros onde este grupo tem seu registro a partir do presente estudo. Também, pode-se comparar essa paleoictiofauna com outras localidades da América do Sul, como a do Devoniano Superior da Colômbia, onde são encontrados diversos Acanthodii (Burrow et al, 2002) e, também, com material fossilífero da Venezuela, onde alguns grupos semelhantes são encontrados incluindo Antarctilamnideos (Young & Moody, 2002).…”

“…Portanto, mesmo que raros, estavam presentes no hemisfério sul durante o Devoniano. A maioria dessas ocorrências se refere ao gênero Bothriolepis, demonstrando que estes animais estariam bem distribuídos durante o Devoniano (Grande & Eastman, 1986;Johanson, 1998;Janvier & Villarroel, 2000;Young & Moody, 2002;Young & Long, 2005;Janvier, 2007). Possivelmente, tal ausência se deva a pouca quantidade de material fóssil estudado em vez de barreiras ecológicas ou qualquer outro aspecto biológico da fauna local, já que outros grupos também encontrados em localidades sul-americanas estão presentes no registro fossilífero da Formação Pimenteira.…”

-PALEOICHTHYOFAUNA OF THE PIMENTEIRA FORMATION (DEVONIAN), PARNAÍBA BASIN, PI, BRAZIL. The Pimenteira Formation extends through the east border of the Parnaíba Basin and corresponds to the Middle and Upper Devonian (Eifelian-Frasnian). This formation possesses as characteristic fauna an invertebrate association composed mostly of gastropods, brachiopods and trilobites. However, there are also rare vertebrate remains, normally isolated and poorly preserved. The vertebrate fauna have been studied since the middle of the twentieth century and until then, had not shown a considerable taxonomic variety, only comprising Ctenacanthus and Machaeracanthus spines. In this study, besides discussing the fossil fish material already known for this formation, we describe new fossil remains, including the description of: a new Machaeracanthus spine; the first spines of climatiiform acanthodians, one related to Ptomacanthus and the other to Climatius enodicosta; an Antarctilamna-like spine; and fragments of Ctenacanthus kegeli. Lastly, we present the possible first record of Placodermi for the Pimenteira Formation and the Parnaíba Basin. These occurrences expand considerably the vertebrate faunal composition of the Pimenteira Formation and helps to understand the connections among South American basins during the Devonian, due to the similarity between the Pimenteira Formation and other South American fossiliferous formations, especially those of Bolivia.

Most reports of Paleozoic and Mesozoic vertebrates from Venezuela are anecdotical, with few detailed descriptions of mostly 'fish' groups. Synapsids (e.g., mammals) are totally unknown, and dinosaurs are only reported from the La Quinta Formation. At least 14 formally recognized geological formations contain fossil vertebrates, most from the Central and Western parts of the country. In the Devonian there is a significant contrast between the vertebrates of Venezuela and Colombia and those of more southern parts of South America. Marine reptiles are present in a few localities in western Venezuela, and are very fragmentary, with one exception. A mosasaur from the Cretaceous La Luna Formation, reported here for the first time, is the most complete vertebrate (tetrapod) from the Cretaceous of Venezuela, and includes a partial skull and a few postcranial remains.
