Fig. 3. Measurements taken in situ on footprints and trackways. Anteroposterior track length: distance between the distal tip of digit III and the proximal boundary of the sole; mediolateral track width: distance between the distal tip of lateral digits measured perpendicular to the track axis; pace angle: angle formed by the two segments joining three consecutive tracks; pace, distance between two consecutive tracks; stride length: distance between two consecutive tracks on the same side (left or right) of the trackway.
Dinosaur footprint from Hanover Point, IOW, UK.
An ornithopod dinosaur (iguanodontian) footprint 3D model from Hanover Point, Isle of Wight, United Kingdom. Its measurements for its foot length is 59 cm and foot width is 65 cm. The pink pencil for scale is 15 cm long and is located on the middle digit. Scanned on 17th September, 2021. For academic and educational purpose only. Source: Objaverse 1.0 / Sketchfab
Data from: Shape variability in tridactyl dinosaur footprints: the significance of size and function
The functional anatomy of the hindlimb of bipedal dinosaurs has been intensively studied. Yet, surprisingly little work has been done concerning functional adaptations in the digits for terrestrial locomotion. While complete and articulated pes skeletons are scarce, pes shape is abundantly recorded by fossil footprints. Here we aim to elucidate the significance of footprint shape and size for locomotion using a large sample (n = 303) of tridactyl dinosaur footprints from a broad range of geographic localities and time slots. Size and shape variation is characterised separately for theropods and ornithischians, the two principal trackmaker taxa. At smaller sizes, theropod footprints are best discriminated from ornithischian footprints based on their smaller interdigital angle and larger projection of digit III, while at larger sizes digital widths are effective discriminants. Ornithischian footprints are shown to increase in size from the Early Jurassic to the Late Cretaceous, a trend not observed in theropod footprints. Size and function are argued to be important determinants of footprint shape, and an attempt made to infer function from shape. Digit III projection and length-to-width ratio of the footprints are negatively correlated with size in both trackmaker groups, while digit impression widths are positively correlated with size only in ornithischians. Digit III projection is proposed to be positively correlated with cursorial ability. Increased interdigital angles are associated with a decrease in digital widths, possibly representing an adaptation for stability. Footprints are found to yield great unrecognised potential for the understanding of the functional morphology of dinosaur feet.

Dinosaur footprint (cf. Anomoepus isp.)
The presented specimen was found in Czerwone Żlebki [literally Red Couloirs], in the peak zone (Upper Triassic, from 201.3 to 237 million years ago). The footprint has been preserved on a small piece of sandstone in rock debris. Anomoepus is an ichnologic name applied to the ornithischian dinosaurs described by Edward Hitchcock in 1848. Their traces were found in Poland before in the Świętokrzyskie Mountains [also known as Holy Cross Mtn.], the Czech Republic and Western Australia. Interestingly, ichnologists have not yet managed to find the skeleton of the described species, so it is difficult to recreate the actual appearance of the animal.
