Coprolite external features and taphonomical attributes.
(a–c) Coprolite in dorsal (a), ventral (b) and side (c) views showing desiccation grooves only on the dorsal surface. (d–f) Coprolite in dorsal (d), ventral (e) and side (f) views showing grooves and some pits generated by desiccation and soil detritus on the ventral surface. (g–i) Coprolite in dorsal (g), ventral (h) and side (i) views showing ventral smooth surface, but with very cracked –by desiccation– dorsal and side surfaces. (j–k) Coprolite in dorsal (j) and ventral (k) views showing smooth surfaces, but with lithoclasts on the ventral surface –black arrows in (k)–.
