Fossil assemblage, paleoenvironment and biochronologic interval.
(A) Prorotodactylus mesaxonichnus isp. nov. (B) cf. Rotodactylus. (C-E) Chirotheriid tracks: Morphotype I (C), Morphotype II (D) and Morphotype indet. (E). (F-H) Rhynchosauroides tracks: R. cf. schochardti (F), R. isp. indet. 1 (G) and R. isp. indet (H). (I) Undetermined Morphotype A. (J, K) Swimming scratches of Characichnos isp. of small (J) and large (K) size. (L) Arthropod body impressions. (M) Invertebrate burrows. (N) Trunk mark. (O) Plant remain. (P) Paleoenvironmental reconstruction of the Triassic Pyrenean Basin (faunas and plants are not scaled). (Q) Prorotodactylus-Rotodactylus zone (P.-R. zone; grey interval) correlated with the Triassic biochronological intervals (see text for explanation of 1, 2 and 3). FAD: First Appearance Datum.
