Papers in Palaeontology, Volume 12, Issue 4, July/August 2026.Abstract Freshwater fishes from the northwestern Colombian Andes are reported from the Pliocene Sincelejo and Ware formations. A total of 10 taxa have been identified, involving two orders, five families and nine genera. Characters from dental morphology, fin spines and cranial bones are provided as taxonomic tools for the study of fossil fishes.

Papers in Palaeontology, Volume 12, Issue 4, July/August 2026.Abstract Cambrian Series 2 represents a key interval for documenting the evolution and diversification of early biomineralized skeletal animals. In this interval, small shelly fossils (SSF) provide an essential archive for regional biostratigraphy and intercontinental correlation.

Carnets de Géologie, 2008 L'étude des microfossiles extraits par acétolyse des niveaux carbonatés indurés de la série campano-maastrichtienne du stratotype de limite à Tercis (Landes, France) a permis de découvrir 44 taxons attribués au groupe des gilianelles (microproblematica ...

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.Abstract The Valanginian positive carbon isotope excursion (Weissert Event, ca. 135 million years ago) documents a major global carbon cycle and climate perturbation. Radioisotopic dating suggests that this event was broadly contemporaneous with an interval of profoundly enhanced volcanic activity during the emplacement of the Paraná–Etendeka Large ...

Carnets de Géologie, 2004 In the middle of the last century Gargasian strata overlying the historical stratotypic beds of the lower substage of the Aptian (Bedoulian) were still well exposed in a number of quarries that extended in a NNE-SSW trending belt from the village of ...

Search for impact ejecta at the Paleocene–Eocene boundary
Meteoritics &Planetary Science, Volume 61, Issue 7, Page 1585-1592, July 2026.Abstract Almost 10 years have passed since microtektites and microkrystites were reported for the Paleocene–Eocene (P–E) boundary in drill cores and outcrop in New Jersey and in ODP Hole 1051B in the western North Atlantic. The glassy spherules were interpreted to reflect an impact trigger for the Paleocene–Eocene Thermal Maximum (PETM).

The Depositional Record, Volume 12, Issue 3, June 2026.New bio‐sequence framework for the Eocene–Oligocene transition in Zagros. Geochemical data validate basin depth control on SB1 vs. SB2 boundaries. SEM‐EDS analyses confirm subaerial exposure versus continuous deposition. Sensitivity analysis quantifies sub‐10% uncertainty in stratigraphic interpretations. Resolves the Pyrenean orogeny's variable impact
