Early Cretaceous Turtle Tracks and Skeletons From the Junggar Basin, Xinjiang, China

A diversified vertebrate ichnite fauna from the Feitianshan Formation (Lower Cretaceous) of southwestern Sichuan, China

“…Although BJA-TU1 is an isolated specimen, it is morphologically similar to turtle swim tracks (Avanzini et al, 2005), such as MGCM.G3.RM1 from the Huangyangquan tracksite (Xing, Avanzini et al, 2014). MGCM.G3.RM1 is slightly smaller, 18.9 cm long and 2.6 cm wide than BJA-TU1.…”

“…Lockley, Xing, Li, Li, and Matsukawa (2012) Xing, Avanzini et al (2014) described turtle tracks from Huangyangquan in detail and suggested that they were similar to the ichnogenera Chelonipus and Emydhipus. Moreover, new observations on the holotype of Laiyangpus liui (Li, J.J., pers.…”

Tracking the yellow dragons: Implications of China's largest dinosaur tracksite (Cretaceous of the Zhucheng area, Shandong Province, China)

“…Allowing for the areas where outcrop is missing within the walled area the total bedding plane surface is on the order of 1400 m 2 . Preliminary results of this phase of the work were presented at the 11th Mesozoic Terrestrial Ecosystems Symposium where the map was presented (Lockley et al, 2012b) and it was reported that the site was only one of three in China where turtle tracks had been discovered, in 2011, and simultaneously reported, with notice of those found that same year in Nei Mongol and Xinjiang (Xing et al, 2014) as the first described from China (Lockley et al, 2012c). The aforementioned, re-location of the lost Liayangpus holotype adds a fourth occurrence of Cretaceous turtle tracks to the three reported in 2012 though 2014.…”

Tetrapod swim techniques interpreted from swim trace fossils from the Lower Triassic Baranów Formation, Holy Cross Mountains, central Poland

“…However, the ridges representing digital imprints of turtles form well-defined tracks and footmarks with no sine-shaped configuration (cf. Lockley and Foster 2006;Xing et al 2014).…”
