The research history of the Middle Triassic fishes of Monte San Giorgio: getting out of the shadow of aquatic reptiles

Swiss Journal of Palaeontology
Around the middle of the nineteenth century, Italian palaeontologists began to investigate fossils of fishes and reptiles from the Middle Triassic outcrops in the vicinity of Monte San Giorgio (Canton Ticino, Switzerland).

Cautionary tales on the use of proxies to estimate body size and form of extinct animals

Ecology and Evolution, Volume 14, Issue 9, September 2024.
Reconstructing the body size and form of extinct animals is of vital importance to our understanding of macroevolution and palaeontology. This is often done using anatomical proxies where extinct species are known only from fragmentary remains. However, there are many limitations influencing the selection of proxy taxa that are frequently overlooked ...

Darwin, Haeckel, and the “Mikluskan gas organ theory”

Developmental Dynamics, Volume 253, Issue 4, Page 370-389, April 2024.
Abstract A previously unknown reference to the Russian ethnologist, biologist, and traveler Nikolai N. Miklucho‐Maclay (1846–1888) was discovered in correspondence between Charles Darwin (1809–1882) and Ernst Haeckel (1834–1919). This reference has remained unknown to science, even to Miklucho‐Maclay's biographers, probably because Darwin used the ...

The spotted parrotfish genome provides insights into the evolution of a coral reef dietary specialist (Teleostei: Labridae: Scarini: Cetoscarus ocellatus)

Ecology and Evolution, Volume 14, Issue 3, March 2024.
The genome of the spotted parrotfish provides insight into the evolution of a coral reef specialist. Expansion and selection of detoxifying genes suggest a potential role in the metabolism of harmful dietary targets. Abstract With over 600 valid species, the wrasses (family Labridae) are among the largest and most successful families of the marine ...

Telencephalic eversion in embryos and early larvae of four teleost species

Evolution &Development, Volume 26, Issue 2, March 2024.
The telencephalon of ray‐finned fishes undergoes eversion, not evagination as in the rest of vertebrates. We show that the formation of the ventricle followed by a rostro‐caudal telencephalic expansion is key for the formation of an everted telencephalon in teleosts.

Sarcopterygii do Eopermiano da Bacia do Paraná, Estado de São Paulo

Revista do Instituto Geológico, 2012
Esta contribuição constitui uma revisão dos Sarcopterygii (Coelacanthimorpha - celacantos; Tetrapodomorpha - Osteolepimorpha e tetrápodes) do Eopermiano da Bacia do Paraná no Estado de São Paulo. O outro grupo importante de sarcopterígeos - Dipnoi (peixes pulmonados) - ainda não foi registrado nesse estado no Eopermiano.

Large Tristichopteridae (Sarcopterygii, Tetrapodomorpha) from the Late Famennian Evieux Formation of Belgium [PDF]

Palaeontology, 2002
Remains of two large sarcopterygians are described from Famennian deposits in Belgium. One of them is referred to Eusthenodon wängsjöi Jarvik; it is the first occurrence of this genus in Belgium. The other, much larger one, appears to be a tristichopterid.

Phylogenetic analysis of the SAP30 family of transcriptional regulators reveals functional divergence in the domain that binds the nuclear matrix

BMC Evolutionary Biology, 2009
Background Deacetylation of histones plays a fundamental role in gene silencing, and this is mediated by a corepressor complex containing Sin3 as an essential scaffold protein.

A Late Devonian coelacanth reconfigures actinistian phylogeny, disparity, and evolutionary dynamics

Nature Communications
The living coelacanth Latimeria (Sarcopterygii: Actinistia) is an iconic, so-called ‘living fossil’ within one of the most apparently morphologically conservative vertebrate groups.

The nanos1 gene was duplicated in early Vertebrates and the two paralogs show different gonadal expression profiles in a shark

Scientific Reports, 2018
Nanos are RNA-binding proteins playing crucial roles in germ cell development and maintenance. Based on phylogenetic and synteny analyses, this study reveals that nanos1 gene has undergone multiple duplications and gene copies losses in Vertebrates ...
