New techniques for old bones: Morphometric and diffeomorphometric analysis of the bony labyrinth of the Reilingen and Ehringsdorf Neandertals

The Anatomical Record, EarlyView.
Abstract Neandertals are known to possess very distinctive traits in their bony labyrinth morphology, such as an inferiorly positioned posterior canal and a very low number of turns in the cochlea. Hence, the inner ear has been often used to assess the Neandertal status of fragmentary fossils.

Geology as a Metaphor in Graham Swift’s Ever After (1992)

Études Britanniques Contemporaines, 2023
In Ever After, Graham Swift’s fifth novel, Matthew Pearce, the main narrator’s ancestor, is a Victorian surveyor who chronicles in his Notebooks how his reading of Charles Lyell’s Principles of Geology (1830-1833) and Charles Darwin’s On the Origin of ...

An osteohistological analysis of Triceratops (Ornithischia: Ceratopsidae) cranial ornamentation

The Anatomical Record, EarlyView.
Abstract Ceratopsids are among the most distinctive and well known extinct Cretaceous vertebrates, yet many details regarding the growth and composition of their cranial features are still not fully anatomically described or understood. In particular, striking cranial adornments such as the postorbital horns and parietal‐squamosal frill of Triceratops ...

Nasal soft‐tissue anatomy of Triceratops and other horned dinosaurs

The Anatomical Record, EarlyView.
Abstract Although ceratopsid dinosaurs possess a characteristically hypertrophied narial region, soft‐tissue anatomy associated with such a skeletal structure and their biological significance remain poorly understood. The present study provides the first comprehensive hypothesis on the soft‐tissue anatomy in the ceratopsid rostrum based on the Extant ...

A new arthropod appendage from the Guanshan Biota (Cambrian) and the functional diversity of arthropod suspension-feeding over the PhanerozoicA new arthropod appendage from the Guanshan Biota (Cambrian) and the functional diversity of arthropod suspension-feeding over the Phanerozoic [PDF]

Royal Society Open Science
Suspension-feeders, animals that capture floating particles from a suspension, have been crucial to the evolution of marine ecosystems throughout the Phanerozoic.

Paraseqences in the Kotroman Formation, Western Serbia [PDF]

Geološki Anali Balkanskoga Poluostrva, 2011
An attempt was made to describe two parasequences separated within the sediments of the Kotroman Formation at the Mokra Gora Village in western Serbia. The whole formation, of Albian-Cenomanian age, in some general characteristics corresponds to

A second species of non‐crocodyliform crocodylomorph from the Late Triassic fissure deposits of southwestern UK: Implications for locomotory ecological diversity in Saltoposuchidae

The Anatomical Record, EarlyView.
Abstract The Late Triassic–Early Jurassic fissures of the Bristol Channel area (southwest England and south Wales) are renowned for their diverse vertebrate faunas. These assemblages have yielded an array of predominantly small‐bodied forms that are crucial to our understanding of the early evolution of several major tetrapod clades.

Palaeontology: The New Conservative [PDF]

Current Biology, 2010
Cambrian Orsten-type fossils have yielded specimens with a uniquely detailed morphology from the early stages of animal evolution. A newly discovered crustacean larva illustrates how morphology and lifestyle over half a billion years ago closely resembled those of extant relatives.

Inter‐ and intraspecific variation in theropod dinosaur dental microwear and its palaeoecological implications

The Anatomical Record, EarlyView.
Abstract Differences in skull and tooth morphology, stomach contents, and estimated bite force between medium‐to‐large sized (≥100 kg) predatory theropod dinosaurs have long been suspected to correlate with differences in their diets and dietary guilds (e.g., hypercarnivory, piscivory).

DNA, spectroscopic and geochemical analyses of bone fragments and associated speleothems in Postojna cave, Slovenia

Acta Carsologica, 2020
a loose/broken stalagmite containing small fragments of cemented bones were collected from the Postojna Cave to investigate whether deoxyribonucleic acid (DNA) can be determined.
