The palaeoecology of two Scottish encrinites: Jurassic crinoid assemblages from the Trotternish Peninsula, Isle of Skye, Scotland [PDF]

open access: yes, 2009
Despite a long history of investigation, articulate crinoids from the Jurassic of Scotland have not received great attention compared to their counterparts in Southern England or continental Europe; this is thought to be largely due to poor preservation.

Carrion ecology: concepts, interdisciplinary synthesis, and perspectives

open access: yesBiological Reviews, Volume 101, Issue 6, Page 2839-2873, December 2026.
ABSTRACT Carrion is a ubiquitous resource in both terrestrial and aquatic ecosystems, yet it has long been overlooked in ecological research. Over the past two decades, studies on carrion and the many organisms that exploit it have flourished, revealing not only wide‐ranging ecological functions but also significance far beyond ecology.

Reconstruction of Rock Uplift in South‐Central Germany Since Late Mesozoic Times

open access: yesGeophysical Research Letters, Volume 53, Issue 21, 16 November 2026.
Abstract Rock uplift and denudation act as first‐order controls on geological processes that influence atmospheric and ocean composition, and landscape‐forming processes. However, estimating rock uplift rates remains challenging due to the temporal averaging of rates calculated from individual thermo‐ or geochronologic systems.

An ontological morphological phylogenetic framework for living and extinct ray‐finned fishes (Actinopterygii)

open access: yesThe Anatomical Record, Volume 309, Issue 11, Page 3187-3217, November 2026.
Abstract The ray‐finned fishes include one out of every two species of living vertebrates on Earth and have an abundant fossil record stretching 380 million years into the past. The division of systematic knowledge of ray‐finned fishes between paleontologists working on extinct animals and neontologists studying extant species has obscured the ...

Cranial anatomy of a Late Cretaceous aspidorhynchid fish (Neopterygii: Aspidorhynchiformes) from Alberta, Canada

open access: yesThe Anatomical Record, Volume 309, Issue 11, Page 3123-3136, November 2026.
Abstract Belonostomus longirostrisis was named for an isolated jaw fragment from freshwater Upper Cretaceous (Campanian) sediments of the Dinosaur Park Formation of Alberta, Canada. Following the description of the Albertan species, numerous isolated cranial and postcranial elements have been collected from the Dinosaur Park Formation and assigned to B.

Comparative cranial biomechanics reveal macroevolutionary trends in theropod dinosaurs, with emphasis on Tyrannosauroidea

open access: yesThe Anatomical Record, Volume 309, Issue 11, Page 3036-3076, November 2026.
Abstract Tyrannosaurus is viewed as a model organism in vertebrate paleontology, with numerous studies analyzing its feeding biomechanics. Nonetheless, the evolution of this feeding performance has been under‐addressed in Tyrannosauroidea, especially in basal tyrannosauroids. Here we used muscle‐force reconstruction and finite element analysis (FEA) to
