Trilobites from Silurian reefs in North Greenland by Helen E Hughes and Alan T. Thomas. 2014. 102pp., 36 figs, 2 tabs. Well preserved trilobite faunas from Telychian reefs in N. Greenland are described and ascribed to 29 genera, of which 4 are new. 23 new species are named, and there are a further 39 under open nomenclature. Much of the material appears to have been concentrated in cavities and depressions on the surface of cement-rich microbial buildups above storm wave-base, and a number of associations are recognised.
