A fragment of a turtle carapace from the Middle Danian bryozoan limestone at the Faxe quarry, eastern Denmark, is identified as a partial costal plate from the carapace of a chelonioid turtle. The fragment bears traces of three separate acts of predation or scavenging. Two circular bite traces Nihilichnus nihilicus Mikula ́s ̌ et al. 2006, 4 mm in diameter, situated 2.5 cm apart, are interpreted as crocodylian. Groups of parallel scrapes, Machichnus bohemicus Mikuláš et al. 2006, 4-5 mm long and 0.5 mm wide, are interpreted as bite traces from sharks. Small circular traces, ~1 mm in diameter, found either alone or in a row of three, are either from sharks or fish. This is the first record of turtles from the Danian bryozoan limestone exposed in Faxe quarry, and thus represents an important addition to the Danian vertebrate fauna of Denmark. © 2011 by Bulletin of the Geological Society of Denmark.

Eleven new tracks from the Upper Jurassic of Portugal are described and attributed to the stegosaurian ichnogenus Deltapodus. One track exhibits exceptionally well-preserved impressions of skin on the plantar surface, showing the stegosaur foot to be covered by closely spaced skin tubercles of ca. 6 mm in size. The Deltapodus specimens from the Aalenian of England represent the oldest occurrence of stegosaurs and imply an earlier cladogenesis than is recognized in the body fossil record. Source

During the last few decades, many new ethological categories for trace fossils have been proposed in addition to the original five given by Seilacher. In this article, we review these new groups and present a version of the scheme of fossil animal behaviour originally published by Bromley updated with regard to modern ethological concepts, especially those of Tinbergen. Because some behaviours are more common in certain environments than others, they are useful in palaeoecological reconstructions, forming the original basis of the ichnofacies concept. To simplify, we summarise some ethological categories as previously done by others. However, the tracemakers behaviour in some cases is so distinctive that subcategories should be employed, especially in ecological interpretations of certain environments where a special behaviour may be dominant. © 2015 Taylor and Francis.

We discuss large tracks recently discovered in Paleocene coal deposits from Svalbard. The age, large size, and excellent preservation of the tracks allows them to be identified to the pantodont Titanoides. This is the earliest evidence of a large mammal on the Arctic islands and the northernmost record from the Paleocene. The traces are described in detail and named Thulitheripus svalbardii, gen. et sp. nov. Large Paleocene pantodonts are previously only known from North America. The presence of pantodonts in the Paleocene strata of Svalbard confirms the postulated DeGeer route for migration of mammals in the Paleocene/Eocene. © 2010 by the Society of Vertebrate Paleontology.

Well-preserved fossil eggs and eggshell fragments from the Pliocene Apolakkia Formation of Rhodes (Greece) are described. The eggs were found in-situ in a clutch. They are sub-spherical with lengths of 53-60 mm and widths of about 40 mm. All eggs are diagenetically compressed and their original diameters are estimated at 45-50 mm. The eggshells are 0.3-0.5 mm thick, partly recrystallized, but widely still aragonitic. They consist of needle-like crystals that form individual shell units. A few pores are preserved between these shell units. This shell-structure allows assignment to chelonian eggs in the oofamily Testudoolithidae and the oogenus Testudolithus. The external morphology, microstructure and mineralogical composition of the eggshells show close resemblance to eggs of the extant tortoise Geochelone elephantopus. Together with a small association of turtle carapace fragments from the same formation, the clutch represents the first discovery of turtle and reptilian remains from the Pliocene of the island of Rhodes. ©2011 E.
