A new species of Lonchidiidae (Hybodontiformes) from the Late Jurassic of Brazil (Aliança Formation, Jatobá Basin)

open access: yesThe Anatomical Record, Volume 309, Issue 11, Page 3091-3105, November 2026.
Abstract The Aliança Formation (Jatobá Basin) represents lacustrine deposits formed in oxygenated waters that hosted a diverse fauna, including Hybodontiform sharks. Within this group, the Family Lonchidiidae comprises 11 valid genera, with Parvodus previously reported in Brazilian deposits from the Brejo Santo Formation (Araripe Basin, Late Jurassic ...

Late Mesozoic marine Antarctic fishes: future perspectives based on the newly collections recovered in the Ameghino and López de Bertodano Formations [PDF]

open access: yesResearch & Knowledge, 2017
Nowadays, notothenioids are the teleostean group that dominates marine Antarctic waters. However, during the Mesozoic a diverse ichthyofauna inhabited the sea that surrounded Antarctic.

Phylogenetic paleobiogeography of Late Ordovician Laurentian brachiopods [PDF]

open access: yesEstonian Journal of Earth Sciences, 2014
Phylogenetic biogeographic analysis of four brachiopod genera was used to uncover large-scale geologic drivers of Late Ordovician biogeographic differentiation in Laurentia. Previously generated phylogenetic hypotheses were converted into area cladograms,

Geological Revolutions in the Late 20th and Early 21st Centuries: Plate Tectonics, Extraterrestrial Impacts, and Snowball Earth

open access: yesNatural Sciences, Volume 6, Issue 3, July 2026.
ABSTRACT During the late 20th and early 21st century three conceptual revolutions reordered our understanding of the history of the Earth: The spread of plate tectonic theory from the 1960s onward which brought geology the first meaningful theory for building mountains and the migration of continents; the rebirth of catastrophism in 1980 with the ...

The genus Coryphodon in Europe: contribution of new exceptional material from Le Quesnoy (northern France, early Eocene, MP7)

open access: yesPapers in Palaeontology, Volume 12, Issue 4, July/August 2026.
Abstract Pantodonts are an extinct group of herbivorous eutherian mammals. They comprise 8 families and 23 genera, ranging from the early Paleocene to the late Eocene, including Bemalambda, Barylambda, Titanoides, or Pantolambda. In Europe, only one genus is known, Coryphodon, represented by three species: C. eocaenus, C. anthracoideus and C.

The origin of mammals: chronology and paleobiogeography [PDF]

open access: yesThe Paleontological Society Special Publications, 1992
A comprehensive review of the stratigraphic and geographic distribution of the advanced, non-mammalian cynodonts (traversodontids, tritylodontids and tritheledontids) and the Late Triassic-Early Jurassic mammals indicates that: (1) traversodontids were a wholly Triassic group that disappeared during the Rhaetian; during the late Carnian-early Norian ...

The present-day Mediterranean brachiopod fauna: diversity, life habits, biogeography and paleobiogeography

open access: yesScientia Marina, 2004
The present-day brachiopods from the Mediterranean Sea were thoroughly described by nineteenth-century workers, to the extent that Logan´s revision in 1979 listed the same 11 species as Davidson, almost 100 years earlier.
