Giant longirostrine crocodylians from the Lower Miocene of Pakistan: new material and taxonomic review

Papers in Palaeontology, Volume 11, Issue 3, May/June 2025.
Abstract This study, based on previously undescribed crocodylian remains from the Lower Miocene of the Bugti Hills (Balochistan, Pakistan), identifies at least three distinct species. It confirms the validity of the species initially identified as ‘Gavialis’ pachyrhynchus, establishing it as the sister taxon to the massive Miocene crocodylian ...

The middle‐upper Eocene Loza‐Portilla Formation (Western Pyrenees, North Spain): Palustrine‐lacustrine carbonate‐dominated sequences in a piggy‐back basin under compressional tectonic stress

The Depositional Record, Volume 11, Issue 1, Page 182-209, February 2025.
The Loza‐Portilla Formation (middle‐upper Eocene) from the Miranda‐Trebiño Basin (Western Pyrenees, N Spain) consisits of alluvial to palustrine‐lacustrine facies associations arranged in three depositional sequences. The lacustrine deposition was controlled by a semiarid climate, compressional tectonism and diapiric influences.
