a, Big spiral bromalite (Institute of Paleobiology, Polish Academy of Sciences (ZPAL) AbIII/3401), presumably from the large dipnoan Ptychoceratodus38, containing a semi-articulated fish (note the close-ups of articulated ganoid scales and a pelvic fin). b, Bite marks and bone-rich bromalites attributed to the archosaur Smok36, exemplified by a dicynodont fibula with tooth marks (ZPAL V.33/471) and a coprolite containing teeth and bones (ZPAL V.33/471). c, Siderite bromalites (Polish Geological Institute—National Research Institute (MUZ PGI OS-221/300 and 306)), most likely produced by large predatory theropods, containing large bones including crocodylomorph limb bones. d, One of several insect-bearing Silesaurus bromalites (ZPAL AbIII/3520) with near-complete specimens of the beetle Triamyxa coprolithica34,35. e, Tooth-bearing temnospondyl bone from regurgitalite ZPAL AbIII/3417a, which also contains fish and supposed archosaur remains (Supplementary Information). Producer: Polonosuchus. f, Plant fossils from herbivore bromalites. Top left, Komlopteris pinna (Palaeozoic and Mesozoic of the National Biodiversity Collection—Herbarium KRAM at the W. Szafer Institute of Botany, Polish Academy of Sciences (KRAM) P PM 68/HS4/13). Top right, abaxial surface and stoma of Desmiophyllum KRAM P PM 68/HS5/25. Bottom left, gingkophyte cuticle with resin bodies, KRAM P PM 68/HS2/5. Bottom right, details of Nilssonia abaxial cuticle from fluorescence microscopy of KRAM P PM 68/PS6/10. See also Barbacka et al.42 and the Supplementary Information.g, Fragment of big fish-bearing coprolite ZPAL AbIII/3440, probably produced by the phytosaur Paleorhinus, and close-ups of a tooth plate and articulated fish vertebrae. h, Fragments of plant-bearing elongated bromalites (ZPAL V.33/1203, ZPAL V.33/1206 and ZPAL V.33/1037). i, Plant fragments from acid-dissolved dicynodont bromalites (ZPAL V.33/1107-1109). The bromalites derive from Krasiejów (a, d, e, g), Lisowice (b, h, i), and Sołtyków (c, f). Scale bars, 10 mm (a, b, c, d (left), e, g (right)); 1 mm (d (right), f (left), g (inset), g (left), h (all)); 0.5 mm (i (left)); 0.1 mm (i (middle)); 50 µm (f (right), i (right)).
