O CROGODILIANO SUL-AMERICANO Carandaisuchus COMO SINONÍMIA DE Mourasuchus (NETTOSUCHIDAE)
Revista Brasileira de Geociências 20(l-4):230-233, março/dezembro de 1990 O CROGODILIANO SUL-AMERICANO Carandaisuchus COMO SINONÍMIA DE Mourasuchus (NETTOSUCHIDAE) JEAN-CLAUDE BOCQUENTIN* e JONAS PEREIRA DE SOUZA FILHO* ABSTRACT THE SOUTH AMERICAN CROCODILIAN CARANDAISUCHUS AS SYNONYMY OF MOURASUCHUS (NETTOSUCHIDAE). New crocodilian skull from the Rio Acre region (Late Miocene-Pliocene) of Brazil provides a basis to establish synonymy between the generic names Mourasuchus, Price, 1964 and Carandaisuchus Gasparini, 1985 the former name is prior to the later, thus, the family Nettosuchidae as here understood includes the species Mourasuchus nativus (Gasparini 1985). Keywords: South American, Miocene, Crocodylia, synonymy. RESUMO Os restos fósseis apresentados neste trabalho procedem da região do Rio Acre (Mioceno Superior-Plioceno), Brasil. Baseando-se no estudo de um crânio de crocodilfdeo, os autores propõem consi- derar Carandaisuchus Gasparini 1985 como sinônimo de Mourasuchus Price 1964, de modo que a espécie previamente denominada Carandaisuchus nativus Gasparini pode ser incluída dentro da família Nettosuchi- dae sob o nome de Mourasuchus nativus (Gasparini 1985). Palavras-chaves: América do Sul, Mioceno, Crocodylia, sinonfmia. INTRODUÇÃO O presente trabalho discorre sobre o achado de um crocodiüano de grande porte encontrado nos sedimentos do Mioceno Superior do Estado do Acre, Brasil. Este material, coletado pela equipe de pesquisas paleontológi- cas da Universidade Federal do Acre em setembro de 1987, foi interpretado à primeira -
Lower Miocene Alligatoroids (Crocodylia) from the Castillo Formation, Northwest of Venezuela
Palaeobiodiversity and Palaeoenvironments https://doi.org/10.1007/s12549-018-0332-5 ORIGINAL PAPER Lower Miocene alligatoroids (Crocodylia) from the Castillo Formation, northwest of Venezuela Andrés Solórzano1,2 & Ascanio D. Rincón1 & Giovanne M. Cidade3 & Mónica Núñez-Flores1,4 & Leonardo Sánchez1 Received: 23 June 2017 /Revised: 27 December 2017 /Accepted: 14 May 2018 # Senckenberg Gesellschaft für Naturforschung and Springer-Verlag GmbH Germany, part of Springer Nature 2018 Abstract Crocodyliform diversity was particularly high during the middle and late Miocene of South America, with up to 12 species recovered from a single geological unit. Nonetheless, the early Miocene fossil record of low-latitude vertebrates is scarce; hence, crocodylians remain poorly known in the region. The Castillo Formation, located in the northwest of Venezuela, preserves an interesting vertebrate fauna with a well-constrained late early Miocene age. Previous work dealing with crocodylians of this formation only recorded three taxa: the gavialoid Siquisiquesuchus venezuelensis and Gryposuchus sp. and indeterminate alligatoroid remains. New cranial and mandibular material recently recovered from the Castillo Formation allows us to document four previously unrecognised alligatoroid forms: Purussaurus sp., Caiman sp., an indeterminate caimanine and an indeterminate alligatoroid. With six taxa, the crocodylian assemblage reveals a previously undocumented relatively high taxonomic diversity in the early Miocene. The Castillo crocodylians show a broad range of morphological disparity and body sizes ranging from small (2.5 m–62 kg) to large (7.5 m–1600 kg) taxa. Thus, crocodylian niche partition, as well as the abundance and variety of resources and environmental heterogeneity of aquatic ecosystems in South America, were already established by at least the early Miocene. -

Mourasuchus is one of the most peculiar crocodylians of all time, showing an unusual ‘duck-faced’ rostrum with thin, gracile mandibles. It includes four species restricted to the South American Miocene. -

[email protected] ABSTRACT – The Solimões Formation (lower Eocene–Pliocene), southwestern Brazilian Amazonia, is one of the most abundant deposits of reptiles from the Cenozoic of Brazil. Eight species of Crocodylia have been described from this formation, including taxa of all the three main extant clades: Gavialoidea (Gryposuchus and Hesperogavialis), Alligatoroidea (Caiman, Mourasuchus and Purussaurus) and Crocodyloidea (Charactosuchus). Here, we describe crocodylian fossil remains collected in 1974 by RadamBrasil Project. Specimens were described and identified to the possible lowermost systematic level. With the exception of the osteoderms, the associated postcranial elements were not identified. -
