英文摘要	Bromalites (coprolites and possibly some cololites) from a turtle-dominated fossil assemblage from the Upper Triassic of Poland were studied. Bromalites collected at the Poręba site are grouped within four morphotypes (A, B, C, and D) attributable to sharks, medium-sized omnivorous or carnivorous tetrapods (likely turtles), sizable carnivorous archosaurs (likely theropods) and an indeterminate big herbivorous tetrapod (possibly dicynodonts or aetosaurs), respectively. Food residues, abundant eggs (possibly of parasites), and microorganisms were found within the materials. Several lines of evidence suggest that at least part of the type B specimens might have been produced by turtles, since (a) turtles are the prevailing tetrapods in the assemblage (over 4/5 of tetrapod bone remains), (b) coprolites are of adequate size, and (c) they appear to have been produced by a carnivore of a low metabolic rate, as seen in extant turtles. The content of the type B specimens would imply that the Late Triassic turtle Proterochersis porebensis was partly piscivorous, but possibly complemented its diet with a more diversified foodstuff, including plants. Semiaquatic habit of Proterochersis porebensis might also provide a taphonomic explanation of the relative abundance of turtle remains at the Poręba site, Poland. Shark bromalites and coprolite specimens attributable likely to theropod dinosaurs also contain abundant fish remains. Origin and classification of spiral and scroll bromalites left by fish are discussed in addition. © 2019 Elsevier B.V.
