μCT-aided study illuminates the cranial endoskeleton and interrelationships of the Permian actinopterygian †Brachydegma, which is now excluded from crown neopterygians despite exhibiting a double jaw joint.

Porcelaneous foraminifera, marine calcifiers, reveal their biomineralization secrets.

Permian xylophagous beetles suffered a severe extinction during the end-Permian mass extinction largely due to the collapse of forest ecosystems.

Cranial endocasts of fossil and extant lungfish, analysed via tomography and novel principle component analyses designed for use with missing data, show that lungfish forebrain and inner ear regions show the most variation in brain shape evolution through time.

Phylogenomics of sea urchins clarifies their origins and diversification history, reveals surprising discrepancies with their rich fossil record, and serves as basis to explore the sensitivity of time calibration analysis.

X-ray imaging reveals well-preserved internal characters in mineralized arthropods from the Paleogene, urging the reexamination of previously neglected fossil collections.

New morphological information on the Cambrian artiopodan Acanthomeridion, including CT data, demonstrate that dorsal ecdysial sutures likely evolved multiple times within this group.

Columnar architectures, developed in early Cambrian phosphatic-shelled brachiopods, are highly biologically controlled and organic-matrix mediated, which sheds new light on the evolution and adaptation of biomineralization during the Cambrian explosion.

The discovery of a fossil heart in Rhacolepis buccalis demonstrates that it is possible to scrutinize the fossil record for important clues on cardiac structure and evolution.

Hundreds of fossil remains shed new light on the evolution of grasshoppers, gryllids, and katydids and their ecological role 300 million years ago.
