Ontogeny of the malleus in Mesocricetus auratus (Mammalia, Rodentia): Systematic and functional implications for the muroid middle ear

open access: yesThe Anatomical Record, EarlyView.
Abstract The three mammalian auditory ossicles enhance sound transmission from the tympanic membrane to the inner ear. The anterior anchoring of the malleus is one of the key characters for functional classification of the auditory ossicles. Previous studies revealed a medial outgrowth of the mallear anterior process, the processus internus ...

Comparing different machine‐learning techniques to date Nile Delta sediments based on portable X‐ray fluorescence data

open access: yesGeoarchaeology, Volume 38, Issue 1, Page 57-75, January/February 2023., 2023
Abstract Geomorphology generally aims to describe and investigate the processes that lead to the formation of landscapes, while geochronology is needed to detect their timing and duration. Due to restrictions on exporting geological samples from Egypt, modern geoscientific studies in the Nile Delta lack the possibility of dating the investigated ...

Louth Crater: Evolution of a layered water ice mound [PDF]

open access: yesIcarus (2008) 196, 433-445, 2014
We report on observations made of the ~36km diameter crater, Louth, in the north polar region of Mars (at 70{\deg}N, 103.2{\deg}E). High-resolution imagery from the instruments on the Mars Reconnaissance Orbiter (MRO) spacecraft has been used to map a 15km diameter water ice deposit in the center of the crater.

Synapsids and sensitivity: Broad survey of tetrapod trigeminal canal morphology supports an evolutionary trend of increasing facial tactile specialization in the mammal lineage

open access: yesThe Anatomical Record, EarlyView.
Abstract The trigeminus nerve (cranial nerve V) is a large and significant conduit of sensory information from the face to the brain, with its three branches extending over the head to innervate a wide variety of integumentary sensory receptors, primarily tactile.

Stratigraphic and sedimentologic framework for tephras in the Wilson Creek Formation, Mono Basin, California, USA [PDF]

open access: yes, 2018
Numerous tephra layers occur within the late Pleistocene Wilson Creek Formation, where they are interbedded with lacustrine deposits of Lake Russell, the ancestor of present-day Mono Lake. Most of the tephra layers are rhyolitic in composition, and were produced from the Mono Craters.

An integrated biostratigraphy and seismic stratigraphy for the late Neogene continental margin succession in northern Taranaki Basin, New Zealand [PDF]

open access: yes, 2006
Our aim has been to develop an integrated biostratigraphy and seismic stratigraphy for the Pliocene and Pleistocene formations (Ariki, Mangaa, Giant Foresets) in northern Taranaki Basin to better understand the evolution of the modern continental margin ...

A micro‐geoarchaeological investigation of a cultivation pit (maite) on Teti'aroa atoll, Central‐East Polynesia

open access: yesArchaeology in Oceania, EarlyView.
ABSTRACT Cultivation pits represented the principal form of horticultural features developed by past atoll communities in Central‐East Polynesia (CEP), and they are still utilised on some atolls in Oceania. The majority of information about the use of cultivation pits in CEP derives from ethnographic and preliminary archaeological investigations.

Kuwae, Epi and Tongoa Islands: Transformations of a volcanic landscape in central Vanuatu

open access: yesArchaeology in Oceania, EarlyView.
ABSTRACT This paper presents a detailed overview of archaeological research undertaken on Epi and Tongoa, in central Vanuatu. These islands were previously connected to one another and respectively formed the western and eastern portions of Kuwae, one of the largest islands in the Vanuatu archipelago, until the catastrophic Tombuk volcanic eruption ...
