“…The most southern of these 25 is the Zittau Basin (Fig. 1A, B), which was filledmainly by limno-fluvial or limnic clays, silts, sands and thick layers of lignites exploited in the Turów mine [27][28] . Furthermore, there are numerous volcanic rocks of late Eocene, Oligocene and early Miocene age 28 .…”

“…No animal fossil remains have been documented so far from the Oligocene-Miocene of the Zittau Basin with exception of burrows of sediment eating fauna 28 . In the course of the present research in the clays of Biedrzychowice Fm., apart from the excrement-shaped ferruginous masses, a fragment of a turtle shell was found.…”

Excrement-shaped siderite masses have been the subject of much controversy. They have been variously interpreted either as being coprolites, cololites or pseudofossils created by mechanical deformation of plastic sediment. Here we report excrement-shaped ferruginous masses recovered from the Miocene of the Turów mine in south-western Poland. Mineralogical, geochemical, petrographic and microtomographical analyses indicate that these masses consist of siderite and iron oxide rather than phosphate, and rarely contain recognizable food residues, which may suggest abiotic origins of these structures. On the other hand, evidence in support of a faecal origin include: (i) the presence of two distinct morphotypes differing in size and shape, (ii) the limited quantity of specimens, (iii) the presence of rare hair-like structures or coalified inclusions and (iv) the presence of fine striations on the surface. Importantly, comparative actualistic studies of Recent vertebrate feces show overall resemblance of the first morphotype (sausage-shaped with rare coalified debris) to excrements of testudinoid turtles (Testudinoidea), whose shell fragment was found in the investigated locality. The second morphotype (rounded to oval-shaped with hair-like structures), in turn, is similar to the feces of some snakes (Serpentes), the remains of which were noted in the Miocene of the neighborhood areas.

The Szamotuły Graben covers the southernmost part of the Permo-Mesozoic Poznań–Szamotuły Fault Zone. Along this regional discontinuity there are several salt structures, including the Szamotuły diapir, over which an extensional graben formed in the Paleogene and Neogene. The graben is located north of Poznań in central- western Poland, and is NW–SE-trending, ~20 km long, 3–5.5 km wide, and up to 160 m deep. It is filled with Lower Oligocene and Neogene sediments, including relatively thick lignite seams. Data from boreholes allow the assignment of the graben-fill sediments to appropriate lithostratigraphic units. Furthermore, analysis of changes in the thickness of these units provides evidence for periods of accelerated graben subsidence or uplift relative to its flanks. As a result, two distinct stages of tectonic subsidence and one inversion in the Paleogene–Neogene evolution of the Szamotuły Graben have been distinguished. Thus, relatively significant subsidence occurred in the Early Oligocene and the middle Early–earliest Mid-Miocene, while slight inversion took place in the middle part of the Mid-Miocene.
