TL;DR: A set of recommendations for minimum standards and additional best practice for three-dimensional digital data publication are proposed, and the issues around data storage, management and accessibility are reviewed.

TL;DR: A comprehensive study of six Pragian-lower Emsian (Lower Devonian) sections from the Spanish Central Pyrenees has yielded a rich assemblage of conodont faunas, highlighting an important succession of Polygnathus species as discussed by the authors.

TL;DR: This study provides strong evidences of an extremely slow dental replacement in this primitive chondrichthyan based on three independents analyses: statistical analysis of the wear degree, demonstrating that teeth remain functional for a long period of time, and estimations of size increments between teeth for some recent sharks whose rates of replacement were known prove that Δs is inversely proportional to the rate of replacement.

TL;DR: Results show that a superficial cap of SCE is present in the oldest shark teeth known, which suggest its presence in the most basal chondrichthyans.

TL;DR: It is demonstrated that the complex microstructure of conodont crown tissue is an adaptation to the dental functions that the elements performed, and informed by occlusal and microwear analyses, the results show topological co-variation in the patterns of stress distri- bution and crystallite orientation.
