Here we report a new quadrupedal trackway found in the Lower Cretaceous Daegu Formation (Albian) in the vicinity of Ulsan Metropolitan City, South Korea, in 2018. A total of nine manus-pes imprints show a strong heteropodous quadrupedal trackway (length ratio is 1:3.36). Both manus and pes tracks are pentadactyl with claw marks. The manus prints rotate distinctly outward while the pes prints are nearly parallel to the direction of travel. The functional axis in manus and pes imprints suggests…

Ichnological evidence for quadrupedal locomotion in pterodactyloid pterosaurs: trackways from the Late Jurassic of Crayssac (southwestern France)
Abstract More than 30 well-preserved pterosaurian trackways have been excavated from the site of Crayssac (Lower Tithonian, southwestern France), along with hundreds of isolated imprints. The general

The choristoderan reptile Monjurosuchus from the early Cretaceous of Japan
A cladistic analysis was performed in order to place Japanese and Chinese taxa, including the incompletely described Chinese long-necked Hyphalosaurus lingyanensis, into choristoderan phylogeny, and the results support the monophyly of Neochoristodera and a Sino-Japanese clade of long necked Choristoderes.
Trackways of the American Crocodile (Crocodylus acutus) in Northwestern Costa Rica: Implications for Crocodylian Ichnology
American crocodile footprints and trackways are similar to those observed in other extant crocodylian species, indicating substantial trackway conservatism across the group.
Lizards ran bipedally 110 million years ago
The predominant pes tracks, the long stride length of pes, narrow trackway width, digitigrade manus and pes prints, and anteriorly oriented long axis of the fourth pedal digit indicate that these trackways were made by lizards running bipedally, suggesting that bipedality was possible early in lizard evolution.
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.
Re-evaluation of Chelichnus tazelwürmi, a non mammalian therapsid-grade track from the Upper Permian Arenaria di Val Gardena
Abstract In this paper, a revision of tracks referred to as Chelichnus tazelwürmi is reported. The performed analysis, consisting of a holistic approach by means of a mainly morphological analysis,
The first record of a long-snouted choristodere (Reptilia, Diapsida) from the Early Cretaceous of Ishikawa Prefecture, Japan
A longirostrine choristoderan reptile is described from the Early Cretaceous Tetori Group on the basis of an associated specimen from the Kuwajima Formation, Ishikawa Prefecture. This is the first
