Rapid neck elongation in Sauropterygia (Reptilia: Diapsida) revealed by a new basal pachypleurosaur from the Lower Triassic of China

BMC Ecology and Evolution, 2023
Neck elongation has appeared independently in several tetrapod groups, including giraffes and sauropod dinosaurs on land, birds and pterosaurs in the air, and sauropterygians (plesiosaurs and relatives) in the oceans.

Working with laws, regularities and singularities in biology: The evolution of mammalian red blood cell size as a case study

The Anatomical Record, EarlyView.
Abstract Phylogenetic comparative methods have been used in recent literature to work with laws and test for regularities (evolutionary associations of quantitative features) and evolutionary singularities (features that evolved in a single taxon). We analyzed these uses epistemologically, taking the evolution of red‐blood‐cell mean corpuscular volume (

Late Permian and Early Triassic conchostracans from the Babii Kamen section (Kuznetsk coal basin)

Учёные записки Казанского университета: Серия Естественные науки, 2019
The Late Permian and Early Triassic conchostracans from the Babii Kamen section (Western Siberia) were studied. The conchostracans were collected from the section during the field work in 2015–2018.

Exploring the cranial morphology and possible convergences of Triassic non‐crocodylomorph pseudosuchians (Archosauria: Pseudosuchia) with other sauropsids through linear morphometrics

The Anatomical Record, EarlyView.
Abstract Triassic pseudosuchians had highly diversified cranial morphologies. These archosaurs occupied diverse ecological roles, ranging from terrestrial predators and herbivores to semiaquatic ambush predators and possible waders. Here, we apply linear cranial morphometrics to assess possible convergences with other sauropsids from the clades ...

Paleomagnetic Reconstruction of the Early Triassic Paleogeographic Position of the South Yellow Sea and Its Geological Significance

Journal of Marine Science and Engineering
Most studies on the Early Triassic paleomagnetism of the Yangtze Block (YB) have concentrated on the Western to Middle parts, but the South Yellow Sea (SYS) in the Eastern YB (EYB) is relatively lacking.

Evidence for multi-rifting in the Variscan–Alpine cycle transition: insights from the European western Southern Alps [PDF]

Solid Earth
We investigate the transition between the Paleozoic Variscan cycle and the Mesozoic–Cenozoic Alpine supercontinent cycle, both of which have played a pivotal role in shaping the central European–Mediterranean plate architecture.

Understanding the provenance and depositional conditions of Triassic sedimentary rocks from the Spiti region, Tethys Himalaya, India

Journal of Asian Earth Sciences: X, 2023
The Spiti region, renowned as the Museum of Indian Geology, is a world-famous sedimentary succession containing well-exposed sequences from Neoproterozoic to Cretaceous age. In this study, Triassic siliciclastic sedimentary rocks of the Lilang Supergroup

Postcranial anatomy and osteohistology of an early prozostrodont cynodont from the Upper Triassic of Brazil

The Anatomical Record, EarlyView.
Abstract Prozostrodon brasiliensis, a probainognathian cynodont of the clade Prozostrodontia, is recognized as a key taxon for understanding the origin of Mammaliaformes and mammals. Despite detailed investigations of its cranial anatomy, the postcranial skeleton has received comparatively less attention.

On the age of Early Triassic Tupilakosaurus fauna of Eastern Europe

Известия высших учебных заведений: Геология и разведка, 2015
The composition of Tupilakosaurus fauna is adjusted. Land tetrapod assemblage from the Upper Sukhorechka Subsuite of the Buzuluk Depression is excluded from the fauna.

The sauropodomorph biostratigraphy of the Elliot Formation of southern Africa: Tracking the evolution of Sauropodomorpha across the Triassic–Jurassic boundary [PDF]

Acta Palaeontologica Polonica, 2017
The latest Triassic is notable for coinciding with the dramatic decline of many previously dominant groups, followed by the rapid radiation of Dinosauria in the Early Jurassic.
