Trace fossils Lockeia siliquaria James, Ophiomorpha nodosa Lundgren, Parataenidium seymourensis isp. n., Protovirgularia rugosa (Miller and Dyer) and Rhizocorallium jenense Zenker have been described for the first time from the Eocene La Meseta Formation of Seymour (Marambio) Island, Antarctic Peninsula . Determinations of some trace fossils formerly described from this formation have been revised. The whole trace fossils association from the La Meseta Formation points to foreshore-offshore environment as indicated by presence of the Skolithos and Cruziana ichnofacies, and to at least temporal normal salinity.

Trace fossils Phymatoderma melvillensis isp. nov., Thalassinoides isp., ?Nereites isp. and Planolites isp. are reported from the glacio−marine sediments of the Cape Melville Formation (Lower Miocene) of King George Island, West Antarctica. Their occurrence and strong bioturbation of sediments point to an offshore or deeper (outer shelf or upper slope) en− vironment. Deep marine crab Antarctidromia inflata Förster, 1985, has been found in Thalassinoides isp. The tracemaker (?crustacean) of Phymatodermamelvillensis re−reworked pelletal sediments probably during times of food deficiency.

A new ichnogenus and ichnospecies (Solealites ovalis) of etching trace is preserved on the surfaces of clasts from the Savignone Conglomerate (Oligocene) in the Palaeogene Piemonte Basin in NW Italy. It is a shallow, oval depression with a central elevation, which was produced probably by limpet gastropods and served as their home scar, but other gastropods or even sea anemones are not excluded as the trace makers. The conglomerate is interpreted as a deposit of a fan delta, whose clasts have been bioeroded in an intertidal and shallow subtidal shore zone and redeposited to the deeper sea.

An important discovery has been made at Targowisko in southern Poland, where ancient bog-oak trunks with well-preserved remains of great capricorn beetle galleries were found in old sediments of the Raba River. Traces of these insects in fossilized or partially fossilized wood provide valuable information, helping us interpret the ancient environment and climate.

W osadach rzeki Raby na południu Polski odkryto pnie czarnych dębów wraz z dobrze zachowanymi chrząszczami o nazwie kozioróg dębosz. Ślady życia tych owadów w kopalnym lub częściowo kopalnym drewnie dostarczają cennych informacji o środowisku i klimacie.

An early Permian (late Artinskian–Roadian) cladid crinoid (Catacrinidae gen. et sp. indet.) is reported for the first time from the V ø ringen Member of the Kapp Starostin Formation of Spitsbergen. The specimen is partly articulated and preserves a considerable part of its stalk and a complete cup, but only the proximal portions of its arms. Thus, it cannot be identified with any degree of certainty at the generic level. Despite this, our finding is important as it constitutes one of the youngest records of catacrinid crinoids to date and considerably extends the palaeogeographic distribution of this group.

The first recognition of a tracemaker responding to a temporary shift in the redox boundary is recognized. This is recorded by a new trace fossil, Sursumichnus orbicularis igen. et isp. nov., which is established for mound-like structures on the upper surfaces of sandstone beds from the Borjomi Flysch (upper Paleocene–lower Eocene) in the Lesser Caucasus (Georgia). It is connected with the spatangoid echinoid burrow Scolicia de Quatrefages, 1849 and interpreted as a resting trace of the same tracemaker produced after moving up from a deeper position within the sediment. The resting is caused by an episode of unfavourable conditions related to shallowing of the redox boundary. The trace fossil is a component of the Nereites ichnofacies.
