The palaeoneurology of a new specimen of the Middle Triassic dicynodont synapsid Kombuisia frerensis

open access: yesActa Palaeontologica Polonica
The pineal eye is a photoreceptive organ, sometimes called the “third eye”, housed within the parietal foramen of some ectothermic vertebrates (Eakin 1973; Quay 1979).

Preliminary phylogenetic analysis and stratigraphc congruence of the dicynodont anomodonts (Synapsida: Therapsida) [PDF]

open access: yes, 2001
A preliminary phylogenetic analysis of 20 well-known dicynodont taxa was conducted using modern cladistic methods. Many past phylogenetic hypotheses were corroborated, but others conflict with the results of this analysis.

Synapsids and sensitivity: Broad survey of tetrapod trigeminal canal morphology supports an evolutionary trend of increasing facial tactile specialization in the mammal lineage

open access: yesThe Anatomical Record, Volume 309, Issue 4, Page 864-911, April 2026.
Abstract The trigeminus nerve (cranial nerve V) is a large and significant conduit of sensory information from the face to the brain, with its three branches extending over the head to innervate a wide variety of integumentary sensory receptors, primarily tactile.

A suture in time: The ontogeny of cranial suture morphology in mammals

open access: yesJournal of Anatomy, Volume 248, Issue 3, Page 501-516, March 2026.
Mammal cranial sutures are important indicators of the biomechanical and developmental pressures acting upon the skull. Across three prominent sutures dividing the vault of the mammalian skull, divergent patterns emerge both taxonomically and developmentally.

A dicynodont-theropod association in the latest Triassic of Poland [PDF]

open access: yes, 2008
It is generally accepted that during the Triassic the composition of tetrapod faunas underwent a series of fundamental transformations, mainly as a result of diversification of archosaurs and decline of therapsids (Benton 1994, 2004, 2006).

Effective dispersal of fern spore and the ecological relevance of zoochory

open access: yesBiological Reviews, Volume 100, Issue 5, Page 2116-2130, October 2025.
ABSTRACT The mechanisms of fern dispersal are under‐studied and there are few data to support the vectors assumed to drive patterns of sporophyte occurrence and speciation. Although wind is generally the fern spore dispersal vector described in the literature, there has always been competing evidence supporting alternate vectors.

Data from: The cranial morphology, phylogenetic position and biogeography of the upper Permian dicynodont Compsodon helmoedi van Hoepen (Therapsida, Anomodontia)

open access: yes, 2017
Compsodon helmoedi is an obscure dicynodont originally described based on a single specimen from the upper Permian of the Karoo Basin. The discovery of three new specimens of Compsodon from the Luangwa Basin of Zambia and two additional specimens from ...

Redescription of three basal anomodonts: a phylogenetic reassessment of the holotype of Eodicynodon oelofseni (NMQR 2913)

open access: yesFrontiers in Earth Science
The Dicynodontia (Therapsida: Anomodontia) is one of the most successful Permo-Triassic terrestrial tetrapod clades and the oldest specimens are recorded from the middle Permian Eodicynodon Assemblage Zone of South Africa. Their fossil record is abundant

The neodiapsid Thadeosaurus colcanapi from the upper Permian of Madagascar

open access: yesPapers in Palaeontology, Volume 11, Issue 2, March/April 2025.
Abstract The enigmatic neodiapsid Thadeosaurus colcanapi (Lower Sakamena Formation, southwestern Madagascar), sole species of the genus Thadeosaurus, is revised here. The attribution of 12 of the 21 referred specimens is confirmed, spanning all ontogenetic stages, and the anatomy of Thadeosaurus is redescribed in detail with comments on ontogenetical ...

Origin of ferruginous coated grains in the Lower Jurassic palustrine limestones of the Pranhita–Godavari Basin, India

open access: yesThe Depositional Record, Volume 11, Issue 1, Page 44-69, February 2025.
In this article, we have proposed a model for the origin of ferruginous coated grains in a continental rift setting. The association of these iron coated grains with limestones and sub‐aerially weathered microbialites have made them suitable for a comparative assessment of various hypotheses of solute supply and precipitation, which can be relevant for
