Diversification of insects since the Devonian: a new approach based on morphological disparity of mouthparts.
Nel P, Bertrand S, Nel A. Nel P, et al. Sci Rep. 2018 Feb 23;8(1):3516. doi: 10.1038/s41598-018-21938-1. Sci Rep. 2018. PMID: 29476087 Free PMC article.
We showed the absence of major rupture in the evolution of the mouthparts, but six epochs during which numerous innovations and few extinctions happened, i.e., Late Carboniferous, Middle and Late Triassic, 'Callovian-Oxfordian', 'Early' Cretaceous, and 'Albia …

Early members of 'living fossil' lineage imply later origin of modern ray-finned fishes.
Giles S, Xu GH, Near TJ, Friedman M. Giles S, et al. Nature. 2017 Sep 14;549(7671):265-268. doi: 10.1038/nature23654. Epub 2017 Aug 30. Nature. 2017. PMID: 28854173
Modern ray-finned fishes (Actinopterygii) comprise half of extant vertebrate species and are widely thought to have originated before or near the end of the Middle Devonian epoch (around 385 million years ago). Polypterids (bichirs and ropefish) represent the earlie …

Homogenity of geological units with respect to the radon risk in the Walloon region of Belgium.
Tondeur F, Cinelli G, Dehandschutter B. Tondeur F, et al. J Environ Radioact. 2014 Oct;136:140-51. doi: 10.1016/j.jenvrad.2014.05.015. Epub 2014 Jun 20. J Environ Radioact. 2014. PMID: 24953229 Free article.
The present paper examines this question for the Walloon region of Belgium, using a database of more than 18,000 indoor radon measurements. With a few exceptions like the Carboniferous (to be divided into Tournaisian, Visean and Namurian-Westphalian) and the Tertiary (in w …
