The fossil record stays silent: Confusions and conundrums for hominin pelvis evolution

open access: yesThe Anatomical Record, EarlyView.
Abstract The evolution of the hominin pelvis is commonly modeled as a series of stages driven largely by the requirements of bipedal locomotion, reproduction, thermoregulation, and pelvic floor muscular support. These patterns are complicated by variation in canal dimensions in relationship with different changes in overall pelvic breadths. To quantify

Identification of the late Quaternary activity of the littoral fault zone at the Northern Jiangsu province in China

open access: yesFrontiers in Earth Science, 2023
It has been accepted that a littoral fault zone (LFZ) exists at the Northern Jiangsu Province, but its geometric distribution and the late Quaternary activity are still controversial. In this study, to constrain its late Quaternary activity, we collected

Historical birth records from 1896 to 1944 from the Basel maternity hospital, Switzerland, reveal significant obstetric selection pressures

open access: yesThe Anatomical Record, EarlyView.
Abstract Maternal and neonatal morbidity and mortality have declined dramatically during the last century. Historical data are therefore important sources to study the evolutionary selection pressures related to childbirth and how they have fluctuated over time.

Osteohistological evidence for terrestrial adaptation and an extended growth period in mekosuchine crocodylians and its potential role in their extinction

open access: yesThe Anatomical Record, EarlyView.
Abstract The Australasian crocodylian fossil record is dominated by the extinct endemic clade Mekosuchinae, with known members spanning the Eocene‐to‐Holocene. This diverse clade exhibited high morphological disparity, from early members superficially similar to Crocodylus, to more terrestrial forms later in the clade's evolutionary history.

Short-tailed mice with a long fossil record: the genus Leggadina (Rodentia: Muridae) from the Quaternary of Queensland, Australia [PDF]

open access: yesPeerJ, 2018
The genus Leggadina (colloquially known as ‘short-tailed mice’) is a common component of Quaternary faunas of northeastern Australia. They represent a member of the Australian old endemic murid radiation that arrived on the continent sometime during the ...

Redescription of the cranial morphology of Amphisbaena braestrupi and Amphisbaena laurenti (Squamata: Amphisbaenidae) from the Pleistocene of Brazil using x‐ray computed tomography

open access: yesThe Anatomical Record, EarlyView.
Abstract Amphisbaenians (Squamata: Amphisbaenidae) are fossorial reptiles with highly specialized cranial morphology, yet their fossil record is frequently limited by fragmentary preservation. This study provides a detailed osteological redescription of the skulls of Amphisbaena braestrupi and Amphisbaena laurenti from the Pleistocene of Lagoa Santa ...

The Human Tibia from Broken Hill, Kabwe, Zambia.

open access: yesPaleoAnthropology, 2009
In 1921, one of the most complete pre-Late Pleistocene human tibiae was discovered at Broken Hill, Kabwe, Zam-bia, apparently directly associated with the Broken Hill 1 cranium. Currently dated to the middle or earlier Middle Pleistocene, the Broken Hill

First Record of Tasmanian Devils in the Pilbara: Late Quaternary Subfossils From Juukan Gorge, Puutu Kunti Kurrama Country, and Insights Into Human—Faunal Relationships and Extinction

open access: yesArchaeology in Oceania, EarlyView.
ABSTRACT This study presents the first unequivocal evidence for the presence of Tasmanian devils (Sarcophilus harrisii) in the Pilbara region of northwestern Australia, based on material recovered from archaeological excavations at Juukan Gorge on Puutu Kunti Kurrama and Pinikura country.

Handaxes and leafpoints industries in the Middle Palaeolithic in northern France: state of knowledge on contexts, chronostratigraphy, typo-technology considerations and their meanings

open access: yesUISPP Journal, 2021
In north-eastern France, the recent phases of the Middle Palaeolithic are characterized by lithic facies without bifaces or with bifaces and very rarely with isolated leafpoint artefacts associated with debitage. Bifaces are tools which are found in very
