Geosciences, 2023 Using cladistic phylogenies (cladograms) to evaluate stratigraphy (taxon distributions and correlations) necessitates various assumptions that include all of the assumptions built into the cladogram, assuming the cladogram is “correct” and that new taxa only arise by dichotomous splitting.

The Depositional Record, EarlyView.Bermuda patch reefs development was primarily controlled by massive coral framework construction, and variation in environmental energy, turbidity and bioerosion. These factors shaped the size, diversity and preservation of the framework, leading to a suppressed, steady vertical accretion.

Anomalously cool clumped isotope temperatures in tropical lagoon carbonates
The Depositional Record, EarlyView.Carbonate clumped isotopes were used to reconstruct paleoclimate from lagoon sediments in the central tropical Pacific. Results were anomalously cool compared to modern measurements and other paleoclimate records. This study highlights the important of understanding carbonate facies and depositional environments in interpreting clumped isotope results.

The Depositional Record, EarlyView.The lower Eocene Alveolina Limestone records the global early Eocene transgression, but is equally affected by tectonic movements of the Montsec active thrust located in its hangingwall. Tectonic movements and the early Eocene transgression facilitated a detrital provenance shift in the southern Pyrenean foreland from a southern provenance in the ...

Chronology of heterogeneous deposits in the side entrance of Postojna Cave, Slovenia
Acta Geographica Slovenica, 2019 The development of the tourist trail in the side passage Rov Novih Podpisov of Postojna Cave in 2001 exposed an over four metres thick sedimentary succession characterised by horizontal flowstone layers intercalated between fine-grained fluvial sediments,

The Depositional Record, EarlyView.Analysing Rare Earth Elements (REEs) and other trace elements together with stable isotope data in poorly preserved belemnites can provide valuable insights into early diagenetic pathways, water‐interaction processes, and even potential redox conditions.
