The sail-backed reptile Ctenosauriscus from the latest Early Triassic of Germany and the timing and biogeography of the early archosaur radiation [PDF]

, 2011
Background Archosaurs (birds, crocodilians and their extinct relatives including dinosaurs) dominated Mesozoic continental ecosystems from the Late Triassic onwards, and still form a major component of modern ecosystems (>10,000 species). The earliest

Sweetospathodus n.gen. and Triassospathodus n.gen., Two Important Lower Triassic Conodont Genera

Geologia Croatica, 2010
Two new Lower Triassic conodont genera, Sweetospathodus n.gen. and Triassospathodus KOZUR n.gen., are described. Sweetospathodus is a transitional form between the platform-bearing gondolellid Clarkina and the platformless Neospathodus.

Intercalibration of Boreal and Tethyan timescales: the magneto-biostratigraphy of the Middle Triassic and the latest Early Triassic from Spitsbergen, Arctic Norway [PDF]

, 2008
An integrated bio-magnetostratigraphic study of the latest Early Triassic to the upper parts of the Middle Triassic, at Milne Edwardsfjellet in central Spitsbergen, Svalbard, allows a detailed correlation of Boreal and Tethyan biostratigraphies.

K-feldspar sand-grain provenance in the Triassic, west of Shetland : distinguishing first-cycle and recycled sediment sources? [PDF]

, 2009
Sandstone provenance studies can help constrain palaeogeographic reconstructions and ancient drainage system scales and pathways. However, these insights can be obscured by difficulties in geochemically distinguishing or adequately characterising ...

A new Early Triassic crinoid from Nevada questions the origin and palaeobiogeographical history of dadocrinids [PDF]

Acta Palaeontologica Polonica, 2023
Knowledge of the early evolution of post-Palaeozoic crinoids mainly relies on the well-preserved and abundant material sampled in Triassic Konservat-Lagerstätten such as those from the Anisian Muschelkalk (Middle Triassic) of the Germanic Basin.

Lower Triassic conodont biostratigraphy of the Guryul Ravine section, Kashmir [PDF]

, 2021
The Guryul Ravine section in Kashmir, northern India is an important reference section for global Lower Triassic stratigraphy. Once a candidate Global Stratotype Section and Point (GSSP) for the Permian-Triassic Boundary (PTB), the section has attracted ...

Magnetostratigraphy of Lower Triassic in Shuiyuguan, Jiaocheng, Shanxi [PDF]

Chinese Journal of Geophysics, 2001
AbstractMagnetostratigraphy of the Lower Triassic Liujiagou and Heshanggou Groups have been established by detailed studies of samples collected from Shuiyuguan, Jiaocheng, Shanxi, China. The magnetic polarities column has a mixed polarity characteristics. The Early Triassic period commences with normal polarity magnetisation.

Reassessment of the evidence for postcranial skeletal pneumaticity in Triassic archosaurs, and the early evolution of the avian respiratory system. [PDF]

, 2012
Uniquely among extant vertebrates, birds possess complex respiratory systems characterised by the combination of small, rigid lungs, extensive pulmonary air sacs that possess diverticula that invade (pneumatise) the postcranial skeleton, unidirectional ...

Temporary expansion to shelf depths rather than an onshore-offshore trend: the shallow-water rise and demise of the modern deep-sea brittle star family Ophiacanthidae (Echinodermata: Ophiuroidea) [PDF]

, 2013
Hypotheses on the age and possible antiquity of the modern deep-sea fauna put forward to date almost all agree on the assumption that the deep-sea fauna is largely the result of colonisation from shallow-water environments. Here, the fossil record of the
