Traces attributed to apterygote insects, arthropleurid myriapods, bivalved arthropods and vermiform animals occur in lake-margin sediments in association with those of temnospondyl
amphibians and early diapsid reptiles, and belong to the Scoyenia ichnofacies.
The vertebrate fauna from those fluvial deposits consists of temnospondyl amphibians (capitosaurs) associated with much rarer archosauriforms and procolophonoid remains as in La Mora site in the Montseny area (4) (Gaete et al., 1993, 1996; Fortuny et al., 2009).
Chirotherium, Rhynchosauroides, and Synaptichnium), and skeletal remains of temnospondyl amphibians (capitosaurs) and terrestrial reptiles (archosauromorphs and procolophonoids).
Temnospondyls are abundant during the Mississippian to Pennsylvanian transition, especially within the Maritimes Basin (Carroll and Gaskill 1978; Carroll 1988, 2009).
The outward directed pes impressions of specimen NBMG 3047, peculiar for temnospondyls, is more commonly observed in the reptilian ichnogenera Notalacerta and Cincosaurus (Haubold et al.
Osteology, variability, and evolution of Metoposaurus, a temnospondyl from the Late Triassic of Poland.
Representing a broad range of depositional environments, ranging from perennial lacustrine to fluvial and aeolian settings, and documented by hundreds of fossils, these assemblages lack any of the characteristic Late Triassic faunal elements, most conspicuously metoposaurid temnospondyls, phytosaurs, procolophonids, and diverse non-crocodylomorph and non-dinosaurian archosaurs, all of which are known from older assemblages in the Fundy basin and elsewhere.
A small temnospondyl amphibian from the Lower Pennsylvanian of Nova Scotia.
]his is based on the fact that in North America and Morocco tetrapod assemblages with only non-metoposaurid temnospondyls are found in strata of Middle Triassic age and are overlain by Late Triassic strata with metoposaurids (Sues and Olsen, personal observations).
