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 ...

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).

Different shape but the same topographical complexity—The lingual gross anatomy of the Saimaa (Pusa saimensis) and Baltic ringed seals (Pusa hispida botnica)

The Anatomical Record, EarlyView.
Abstract Despite the distinctly different shapes of their tongues, the tongue gross anatomy of Saimaa ringed seal closely resembled that of Baltic ringed seal. There were no differences in the extrinsic and intrinsic tongue muscles or their associated vascularization and innervation between Saimaa and Baltic ringed seals.

Effect of climate change on thermal-ice regime of shallow lakes compared to deep lakes: Case study of lakes in the temperate zone (Northern Poland)

Journal of Limnology, 2018
The objective of this study is to determine the usefulness of results of hydrological observations (1961-2015) carried out in a deep lake for the assessment changes in the ice-thermal regime of a shallow lake.

7000 Years of Aboriginal Mining at Sugarloaf Hill in the Riverland Region of South Australia

Archaeology in Oceania, EarlyView.
ABSTRACT Silcrete and chert are commonly represented in Aboriginal archaeological lithic assemblages across large parts of the southwestern Murray‐Darling Basin (MDB). In South Australia (SA), these materials were sourced from a series of quarries located along the incised course of the Murray River through the upper Riverland region.
