Stratigraphic schemes of the Precambrian of the Ukrainian Shield (analytical review)

open access: yesМінеральні ресурси України
The first stratigraphic schemes of the Precambrian of the Ukrainian Shield were compiled in 1926 by V. I. Luchytskyi and D. M. Sobolev, and were subsequently developed by numerous authors until 1967.

Automated stratigraphic interpretation from drillhole lithological descriptions with uncertainty quantification: litho2strat 1.0 [PDF]

open access: yesGeoscientific Model Development
Australian commonwealth, state and territory geological surveys possess information on over 3 million drillhole logs. In addition to mineral exploration drilling, extensive drillhole datasets exist from oil and gas exploration and hydrogeological studies.

A detailed redescription of a skeletally immature ‘Redondasaurus’ suggests ontogenetic transformations in the taxon mirror phytosaurian morphological evolution

open access: yesThe Anatomical Record, EarlyView.
Abstract The study of morphological evolution is fundamentally tied to ontogeny, yet studies of these heterochronic processes in the fossil record are rare. Fossils belonging to an ontogenetic series are difficult to assign to an ontogenetic stage due to inconsistent proxies for skeletal ages, challenging to taxonomically assign due to morphological ...

Application of sequence stratigraphic concepts to the cretaceous Urgonian carbonate platform, southeast France [PDF]

open access: yes, 1992
Carbonate platforms are increasingly being studied using sequence stratigraphic concepts and models borrowed from the study of siliciclastic shelves in passive margin settings. The direct transposition of the stratigraphic model for a siliciclastic shelf

The coelurosaur theropods of the Romualdo formation, early Cretaceous (Aptian) of Brazil: Santanaraptor placidus meets Mirischia asymmetrica

open access: yesThe Anatomical Record, EarlyView.
Abstract The upper carbonate concretion levels of the Romualdo Formation (Aptian, Brazil) have yielded several theropod dinosaur remains, including spinosaurids and the coelurosaurs Santanaraptor placidus and Mirischia asymmetrica, the phylogenetic affinities of which are controversial.
