Egg shape changes at the theropod–bird transition, and a morphometric study of amniote eggs [PDF]
, 2014 The eggs of amniotes exhibit a remarkable variety of shapes, from spherical to elongate and from symmetrical to asymmetrical. We examine eggshell geometry in a diverse sample of fossil and living amniotes using geometric morphometrics and linear ...

A probable oligochaete from an Early Triassic Lagerstätte of the southern Cis-Urals and its evolutionary implications [PDF]
Acta Palaeontologica Polonica, 2020 Oligochaetes, despite their important role in terrestrial ecosystems and a tremendous biomass, are extremely rare fossils. The palaeontological record of these worms is restricted to some cocoons, presumable trace fossils and a few body fossils the most ...

The late Mesozoic-Cenozoic tectonic evolution of the South China Sea: A petrologic perspective [PDF]
, 2014 This paper presents a review of available petrological, geochonological and geochemical data for late Mesozoic to Recent igneous rocks in the South China Sea (SCS) and adjacent regions and a discussion of their petrogeneses and tectonic implications. The

The thermal history of the Western Irish onshore [PDF]
, 2014 We present here a low-temperature thermochronological study that combines the apatite fission-track and (U + Th)/He dating methods with a pseudo-vertical sampling approach to generate continuous and well-constrained temperature–time histories from the ...

Tectonostratigraphic History of Mesopotamian Passive Margin during Mesozoic and Cenozoic, South Iraq. [PDF]
Kirkuk Journal of Science, 2008 Passive margin of Mesopotamian zone formed by two tectonic phases: opening and closing phases. Opening tectonic phase (Permian-Jurassic) represents the beginning of Wilson cycle. This phase includes three stages: pre-rifting, rifting and post-rifting. In
