Seasonality and growth in tropical freshwater ectotherm vertebrates: Results from 1‐year experimentation in the African gray bichir, giraffe catfish, and the West African mud turtle

Autor: Axelle Gardin, Olga Otero, Elodie Réveillac, Alexandra Lafitte, Xavier Valentin, Florian Lapalus, Didier Bouchon, Géraldine Garcia

Publikováno v: Ecology and Evolution, Vol 13, Iss 3, Pp n/a-n/a (2023)

Abstract Growth in ectotherm vertebrates is strongly rhythmed by seasonal variation in environmental parameters. To track the seasonal variation in ancient times in a continental and tropical context, we aim to develop a method based on the use of th

Living Taxa and Their Importance in Understanding the Extinct Diversity: A Look at Polypterid Pinnules

Autor: Marcos Vinícius Coelho, Camila Cupello, Paulo M. Brito, Olga Otero

Publikováno v: Diversity, Vol 15, Iss 4, p 517 (2023)

Pinnules are the peculiar, impaired spines that carry each of the numerous finlets that constitute the dorsal fins of polypterid fishes (Cladistia and Polypteriformes). Previous studies, including a recent detailed paper on the comparative analysis o

Origin and diversification of the Otophysi clade during the Mesozoic: a case of mosaic evolution?

Autor: Diogo Mayrinck, Paulo M. Brito, Jesus Alvarado-Ortega, Olga Otero

Publikováno v: Research & Knowledge, Vol 3, Iss 2, Pp 23-27 (2017)

Almost all distributed today in freshwater, except by few taxa that inhabited coastal marine waters, the Otophysi clade is a group of teleostean with a formerly worldwide distribution in all continents. The Otophysi fossil record is well known by com

Biominerals Fossilisation: Fish Bone Diagenesis in Plio–Pleistocene African Hominid Sites of Malawi

Autor: Christiane Denys, Olga Otero, Ottmar Kullmer, Oliver Sandrock, Timothy G. Bromage, Friedemann Schrenk, Yannicke Dauphin

Publikováno v: Minerals, Vol 10, Iss 12, p 1049 (2020)

Fish fossilisation is relatively poorly known, and skeletal element modifications resulting from predation, burial and diagenesis need to be better investigated. In this article, we aim to provide new results about surface, structural and chemical ch

†Sorbinicharax verraesi: An unexpected case of a benthic fish outside Acanthomorpha in the Upper Cretaceous of the Tethyan Sea.

Autor: Diogo Mayrinck, Paulo M Brito, François J Meunier, Jesus Alvarado-Ortega, Olga Otero

Publikováno v: PLoS ONE, Vol 12, Iss 8, p e0183879 (2017)

†Sorbinicharax verraesi is a marine teleostean fish from the Upper Cretaceous of Nardò (Italy). It was first attributed to the otophysan order Characiformes, which represents potential evidence for the controversial marine origin of the clade. Thr

The phylogenetic intrarelationships of spiny-rayed fishes (Acanthomorpha, Teleostei, Actinopterygii): fossil taxa increase the congruence of morphology with molecular data

Autor: Donald Davesne, Cyril Gallut, Véronique Barriel, Philippe Janvier, Guillaume Lecointre, Olga Otero

Publikováno v: Frontiers in Ecology and Evolution, Vol 4 (2016)

Acanthomorpha (spiny-rayed fishes) is a clade of teleosts that includes more than 15 000 extant species. Their deep phylogenetic intrarelationships, first reconstructed using morphological characters, have been extensively revised with molecular data

A Fish Assemblage from the Middle Eocene from Libya (Dur At-Talah) and the Earliest Record of Modern African Fish Genera.

Autor: Olga Otero, Aurélie Pinton, Henri Cappetta, Sylvain Adnet, Xavier Valentin, Mustapha Salem, Jean-Jacques Jaeger

Publikováno v: PLoS ONE, Vol 10, Iss 12, p e0144358 (2015)

In the early nineteen sixties, Arambourg and Magnier found some freshwater fish (i.e., Polypterus sp., Siluriformes indet. and Lates sp.) mixed with marine members in an Eocene vertebrate assemblage at Gebel Coquin, in the southern Libyan Desert. Thi
