TL;DR: The term ‘work of an animal' should be deleted from the code, and ichnotaxa should be based solely on trace fossils as defined herein, and the following emendations are proposed to the International Code of Zoological Nomenclature.

TL;DR: Investigation of the type material of ‘Sedilichnus’ shows that it probably describes variably shaped oscula and thus is a genuine morphological character of the host sponge Prokaliapsisjanus, rather than a bioerosion trace fossil.

TL;DR: Despite strong correlation during historical time, palaeoecological evidence suggests that marine and terrestrial ecosystems may show dissimilar growth reaction to recently observed positive winter-NAO phases.

TL;DR: In this article, an assemblage of geoduck clam shells from the marine environment of coastal British Columbia was studied and the widths of internal shell growth increments, annuli, were measured from the hinge plate.

TL;DR: Helama et al. as mentioned in this paper presented a multi-proxy reconstruction of temperature histories using a combination of dendrochronological and sclerochronological evidence, and the reconstruction correlated well with the long records of instrumental temperatures from Tornedalen, St. Petersburg, Uppsala and Stockholm.
