Abstract: Many newly-discovered dinosaur tracksites have recently been reported from the Lower Cretaceous Dasheng Group of Shandong Province. These are proving valuable as tools for characterizing the fauna in deposits almost devoid of body fossils. Here we report on a new Cretaceous site, the 14 th documented in recent years, with multiple track-bearing levels, that adds ~300 tracks to a growing database. At least two morphotypes tentatively labelled as cf. Menglongpus isp., representing a deinonychosaur, and cf. Tatar… Show more

“…1A. This is supported by numerous didactyl and narrow-gauge bipedal fossil trackways of Mesozoic age, for which dromaeosaurids or troodontids are the only reasonable makers (e.g., Li et al, 2008; Lockley et al, 2016; Xing et al, 2018; Xing et al, 2015; traces of the distal end of digit II are almost always absent). It is also consistent with osteological range of motion (e.g., Colbert & Russell, 1969; Currie & Peng, 1993; Ostrom, 1969b; Paul, 1988; Senter, 2009) and articulated fossil specimens (e.g., Csiki et al, 2010; Norell & Makovicky, 1997; Xu et al, 2003).…”

“…The highly modified osteology of pedal digit II, in concert with the inference that it was not used in locomotion (Li et al, 2008; Lockley et al, 2016; Xing et al, 2018; Xing et al, 2015), suggests that it was used for a very specific purpose in life. Musculotendon anatomy was therefore probably quite highly adapted (‘tuned’) for that single purpose, in contrast to other muscles in the hindlimb which would be required to execute many different activities (see Hutchinson et al, 2015).…”

“…Tracks preserved as convex hyporeliefs (i.e., natural casts) were digitally photographed (115-164 images of each) from various angles using a Nikon D5 with a 24 mm lens. Photographic jpg images were added to Agisoft Photoscan Professional Edition (Version 1.2.6 build 2038 64 bit) to generate scale-corrected models following the procedure adapted from Xing et al (2018). The 3D models were automatically aligned to the centre of the Cartesian coordinate system using R Studio (Version 1.1.453; Lallensack 2018).…”
