Unfused transverse foramen of the atlas vertebra in the Neandertal lineage fossils. [PDF]

open access: yesAnat Rec (Hoboken)
Abstract In anatomically modern humans, the atlas can display an unfused transverse foramen (UTF) but currently the presence of UTF in the Neandertal lineage is uncertain due to a scarcity of prevalence studies and no exhaustive record of its presence throughout the entire hominin fossil record.

Testing the Dry Refuge Model: Paleoecological Insights From Late Pleistocene Gomphotheres in Ecuador. [PDF]

open access: yesEcol Evol
We present paleontological evidence that may prove the Dry Refuge Model in Ecuador during the Late Pleistocene. ABSTRACT Paleoenvironmental records indicate that Neotropical regions near the Equator experienced reduced rainfall during the Last Glacial Maximum (LGM). However, some records show conflicting environmental signals.

Paleoenvironmental Stasis for the Bioturbating Community During the Paleocene-Eocene Thermal Maximum at the Southern Iberian Margin. [PDF]

open access: yesGeobiology
ABSTRACT During the Paleocene‐Eocene Thermal Maximum (PETM), there was an increase in global temperatures and emissions of isotopically depleted carbon, resulting in a negative carbon isotope excursion (CIE). This climatic event caused a widespread ocean deoxygenation, leading to substantial biotic turnover.

Multiple exostoses and an osteochondroma in a Pliocene canid from Langebaanweg 'E' Quarry (South Africa). [PDF]

open access: yesJ Anat
Overview of XS of pathological radius. Using anatomical descriptions, CT scanning and bone histology, we investigate several skeletal overgrowths of bone (exostoses) in the skeleton of a jackal‐like canid from the world famous Langebaanweg, a Mio‐Pliocene locality in South Africa.

Holocene climate aridification trend and human impact interrupted by millennial- and centennial-scale climate fluctuations from a new sedimentary record from Padul (Sierra Nevada, southern Iberian Peninsula) [PDF]

open access: yesClimate of the Past, 2018
Holocene centennial-scale paleoenvironmental variability has been described in a multiproxy analysis (i.e., lithology, geochemistry, macrofossil, and microfossil analyses) of a paleoecological record from the Padul Basin in Sierra Nevada, southern ...
