Chondrichthyan cytogenetics: A comparison with teleosteans
Journal of Molecular Evolution, 1991Cytogenetic studies on cartilaginous fish conducted in recent years have shown that these vertebrates have peculiarities associated both with the karyotypes and the size and composition of their DNAs. Although the data for this group, which includes about 1000 extant species, are still fragmentary, there appear to be more differences than similarities ...

Ultimate Eocene (Priabonian) chondrichthyans (Holocephali, Elasmobranchii) of Antarctica [PDF]
Journal of Vertebrate Paleontology, 2016 The Eocene La Meseta Formation on Seymour Island, Antarctic Peninsula, is known for its remarkable wealth of fossil remains of chondrichthyans and teleosts. Chondrichthyans seemingly were dominant elements in the Antarctic Paleogene fish fauna, but decreased in abundance from middle to late Eocene, during which time remains of bony fishes increase ...

The deep sea is a relatively stable environment, characterized by cold temperatures and poor or absent light. Relative to inshore shelf habitats, the ocean's deepwater environments remain poorly known. The continued expansion of global fishing into the deep ocean has raised new concerns about the ability of deepwater organisms to sustain the pressures ...

The biostratigraphy of Carboniferous chondrichthyans
Geological Society, London, Special Publications, 2021Abstract Among several groups of fishes existing in the Carboniferous, the Chondrichthyes appear to have the greatest stratigraphic potential. However, despite the long history of investigation into Paleozoic sharks, and especially their teeth, our knowledge of their usefulness in biostratigraphy and palaeoecology is still at an ...

Origin and Radiation of Chondrichthyans
2022This chapter looks at chondrichthyans, which are not primitive fishes, but are highly developed. The first definitive chondrichthyan fossils came from the Early Devonian period, although chondrichthyan-like scales are known to have existed from the early Silurian, and possibly the Ordovician periods.

Biogeographic patterns in the Australian chondrichthyan fauna
Journal of Fish Biology, 2011The major biogeographic structure and affinities of the Australian chondrichthyan fauna were investigated at both interregional and intraregional scales and comparisons made with adjacent bioregions. Faunal lists were compiled from six geographical regions with species from these regions assigned to distributional classes and broad habitat categories ...

Mineralized cartilage in the skeleton of chondrichthyan fishes
Zoology, 2006The cartilaginous endoskeleton of chondrichthyan fishes (sharks, rays, and chimaeras) exhibits complex arrangements and morphologies of calcified tissues that vary with age, species, feeding behavior, and location in the body. Understanding of the development, evolutionary history and function of these tissue types has been hampered by the lack of a ...

Chondrichthyan Evolution, Diversity, and Senses
2019Chondrichthyans are one of two major clades of living jawed vertebrates, with a rich fossil record potentially extending back to the Late Ordovician (455 million years ago, mya). The main groups of chondrichthyans include the chimaeroids, sharks, and skates and rays.
