Chirotherium and first Asian Rhynchosauroides tetrapod trackways from the Middle Triassic of Yunnan, China

ABSTRACT The Middle Triassic (Anisian) Guanling Formation in Yunnan and Guizhou provinces, southwestern China, is well-known for its marine-reptile fauna with numerous well-preserved skeletons.

New record of a stahleckeriid dicynodont (Therapsida, Dicynodontia) from the Late Triassic of southern Brazil and biostratigraphic remarks on the Riograndia Assemblage Zone

This taxonomic proposal and the lithological features of the site support that the outcrop belongs to the Riograndia Assemblage Zone (AZ), and the specimen cannot be referred unambiguously to Jachaleria candelariensis due to the lack of cranial material, it likely represents the second record of the genus in the Triassic of Brazil.

The Ruditayoj-Tunasniyoj fossil area (Chuquisaca, Bolivia): a Triassic chirotheriid megatracksite and reinterpretation of purported thyreophoran tracks

ABSTRACT The South American tetrapod track record is highly diverse and well known mainly from Argentina, Brazil, Bolivia, Chile and Peru. To date, many tracksites are known from Bolivia, most

Upper Paleozoic to Lower Mesozoic Tetrapod Ichnology Revisited: Photogrammetry and Relative Depth Pattern Inferences on Functional Prevalence of Autopodia

In recent years photogrammetry has become an essential tool in the study of tetrapod footprints. Morphological analyses of footprints are interpretative; thus, researchers should use as much

3D Imaging of southernmost Triassic archosaur footprints from Europe (Southern Spain)

The application of 3D photogrammetric models to the analysis of rauisuchian archosaur footprints of the Middle-Upper Triassic of the south Iberian palaeomargin improves the knowledge and



Late Triassic Tetrapod-Dominated Ichnoassemblages from the Argana Basin (Western High Atlas, Morocco)

Diverse tetrapod track assemblages with Scoyenia invertebrate traces were discovered in the Triassic Timezgadiouine and Bigoudine formations of the Argana Basin (Western High Atlas, Morocco). The

New ichnites from the Middle Triassic of the Iberian Ranges (Spain): paleoenvironmental and paleogeographical implications

The Iberian Basin or its present-day expression, the Iberian Ranges, was refilled with red bed sediments of alluvial origin during the late Olenekian–Anisian period represented by the Cañizar

Unusual archosaur trackway and associated tetrapod ichnofauna from Irohalene member (Timezgadiouine formation, late Triassic, Carnian) of the Argana Basin, Western High Atlas, Morocco

ABSTRACT An archosaur trackway consisting of 10 successive pes imprints has been recovered from the Late Triassic Irohalene Member of the Timezgadiouine Formation (Argana Basin, Morocco). Footprints

A reappraisal of the Middle Triassic chirotheriid Chirotherium ibericus Navás, 1906 (Iberian Range NE Spain), with comments on the Triassic tetrapod track biochronology of the Iberian Peninsula

The Triassic track record in the Iberian Peninsula matches the expected record for this age on the basis of a global biochronological approach, supporting the idea that vertebrate Triassic tracks are a useful tool in biochronology.

Middle Triassic tetrapod footprints of southern South America

Abstract. In South America, tetrapod footprints of Middle Triassic age were only described from the Cuyana (Cerro de las Cabras Formation) and Ischigualasto-Villa Union (Los Rastros Formation) basins

Triassic pentadactyl tracks from the Los Menucos Group (Río Negro province, Patagonia Argentina): possible constraints on the autopodial posture of Gondwanan trackmakers

A Late Triassic age is here proposed for the Pentasauropus-bearing levels of the Los Menucos Group and implies that such an autopodial structure was promoted independently from the body size in the putative trackmakers.

Cuencas triásicas del Oeste argentino: origen y evolución

The Triassic basins of western Argentina and northern Patagonia are located along fhe Pacific margin of Southwest Gondwana. They are narrow and elongated depressions oriented NW-SE, floored by a
