Middle Pleistocene revelations: unravelling taphonomic processes in mammals including Mesotherium cristatum (Mesotheriidae, Notoungulata), Corralito Site, Córdoba Province, Argentina

open access: yesPalaeontology, Volume 68, Issue 4, July/August 2025.
Abstract Taphonomic studies of Cenozoic mammals are scarce. We report a study of the taphonomy of the Corralito site (Middle Pleistocene to Holocene), Córdoba Province, Argentina, which documents the last population of the South American native ungulate typotherid Mesotherium cristatum. We discovered two specimens of M.

Paleoecologic and biostratigraphic significance of trace fossils from shallow- to marginal-marine environments from the middle Cambrian (Stage 5) of Jordan [PDF]

open access: yes, 2017
The Hanneh Member (Cambrian Stage 5) of the Burj Formation and the Umm Ishrin Formation of Jordan represent a transgressive-regressive succession that contains twenty-eight ichnotaxa, including vertical burrows (Arenicolites isp., Diplocraterion isp ...

Recurrent constructional pattern of the crustacean burrow Sinusichnus sinuosus from the Paleogene and Neogene of Spain [PDF]

open access: yes, 2016
New occurrences of Sinusichnus sinuosus Gibert 1996 described in the Cenozoic of Spain, evidence the almost continuous fossil record of this ichnospecies from the Upper Cretaceous to the Lower Pliocene.

Dynamic Mud Deposition Along the Fluvial–Tidal Transition Zone in the Waihou River, Aotearoa New Zealand

open access: yesJournal of Geophysical Research: Earth Surface, Volume 130, Issue 3, March 2025.
Abstract The fluvial–tidal transition zone (FTT) is a critical interface where complex interactions between river flow, tides, and sedimentation shape geomorphic systems and influence the dynamics of aquatic environments. However, few previous studies have integrated real‐time hydrodynamic data with sedimentary deposits.

Characterisation and Architecture of Subsurface Strata in the Whatcom Sub‐Basin, Georgia Basin, Canada and USA

open access: yesBasin Research, Volume 37, Issue 2, March–April 2025.
In the Paleogene and with the docking of Siletzia on North America's western margin, the Georgia Basin transitioned from a forearc basin to a forearc depression, and this drove a major re‐organisation of depositional environments and paleodrainages in the region. ABSTRACT Outcrops of sedimentary strata that infill the Georgia Basin, Canada and USA have

Tiering Style and Its Interpretation: Ichnofabric Study in Balikpapan Formation, Kutai Basin, Indonesia

open access: yesJournal of Mathematical and Fundamental Sciences, 2019
The determination of tiering style is an important task in ichnology. Tiering styles can be modeled by using ichnodiversity, the number of behaviors and number of tiers and their relationships.

The Paleontological Context : Ichnology

open access: yes, 2020
Except for some previous records, the first attempts for the study of the lying tracks on sediments started at the beginning of the nineteenth century, as well as the efforts for creating a suitable terminology. Its installation as a scientific discipline began at the end of the nineteenth century.

Leonardo and the Whale

open access: yes, 2019
Around 1480, when he was 28 years old, Leonardo da Vinci recorded what may have been a seminal event in his life. In writing of his travels to view nature he recounted an experience in a cave in the Tuscan countryside: Having wandered for some distance ...
