A nossa expedição à Gronelândia em Julho passado descobriu uma grande quantidade de fósseis que agora aguardam estudo. Um dos artigos mais imediatos sobre as descobertas é relativo a excrementos fósseis (coprólitos). E sim, eu sei que podemos fazer muitas piadas sobre este tipo de investigação!

Milàn, J., Clemmensen L. B., Adolfssen J. S., Estrup E. J., Frobøse N., Klein N., Mateus O., & Wings O. (2012). A preliminary report on coprolites from the Late Triassic part of the Kap Stewart Formation, Jameson Land, East Greenland. New Mexico Museum of Natural History and Science, Bulletin. 57, 203-205.
Abstract: The basal part of the Triassic-Jurassic (Rhaetian-Sinemurian) Kap Stewart Formation, exposed at Jameson Land, East Greenland, yields an extensive coprolite collection from black, parallel-laminated mudstone ("paper shale"), representing an open lacustrine system. Preliminary investigations show three different types of coprolites: elongated cylindrical masses, composed of irregularly wrapped layers; elongated cylindrical masses with constriction marks; and spirally-coiled specimens.
