Evolutionary and Biogeographical History of Penguins (Sphenisciformes): Review of the Dispersal Patterns and Adaptations in a Geologic and Paleoecological Context

open access: yesDiversity, 2022
Despite its current low diversity, the penguin clade (Sphenisciformes) is one of the groups of birds with the most complete fossil record. Likewise, from the evolutionary point of view, it is an interesting group given the adaptations developed for ...

New light on the paleobiogeography of the labyrinth fishes [PDF]

open access: yesResearch & Knowledge, 2017
The labyrinth fishes (Anabantoidei/Anabantiformes) have an African-Asian disjunctive distribution; however, their biogeographical history remains elusive due to the scarcity of their fossil records, especially for the Anabantidae itself, the only ...

They come in all sizes: integrative systematics and morphological radiation of Scherotheca (Lumbricidae, Crassiclitellata). [PDF]

open access: yesCladistics
Abstract Scherotheca is amongst the most diverse earthworm genera within Lumbricidae, exhibiting striking ecomorphological radiation—from small epigeic‐like forms to giant anecic species. Accurate systematics is critical for exploring such diversification.

A new Megatheriinae skull (Xenarthra, Tardigrada) from the pliocene of northern venezuela – Implications for a giant sloth dispersal to central and North America [PDF]

open access: yes, 2018
A skull of a ground sloth from the Pliocene San Gregorio Formation documents a northern neotropical occurrence of a megatheriine that addresses issues on intraspecific variation and biogeography. The new specimen is broadly similar in size and morphology

Note on the paleobiogeography of Compsognathidae (Dinosauria: Theropoda) and its paleoecological implications

open access: yesAnais da Academia Brasileira de Ciências, 2014
The paleobiogeography of the theropod clade Compsognathidae is here reaccessed in order to test the hypothesis of this taxon being adapted specifically to inhabit semi-arid environments.

First clear evidence of Anoplotherium (Mammalia, Artiodactyla) in the Iberian Peninsula: an update on the Iberian anoplotheriines. [PDF]

open access: yesAnat Rec (Hoboken)
Abstract Anoplotheriines (Mammalia, Artiodactyla) were enigmatic, medium‐ to large‐sized ungulates that lived in Western Europe from the late middle Eocene to the earliest Oligocene. The unusual dental and postcranial specializations of these Paleogene mammals have no equivalent in other Cenozoic or contemporaneous artiodactyls on Holarctic landmasses.
