Reconstruction and restoration of the skull of Eolambia. (A) Skull reconstruction of Eolambia in left lateral view by the lead author. Bones in white are unknown, bones in dark grey are based primarily upon the adult holotype (CEUM 9758) or paratype (CEUM 5212), and bones in light grey are based primarily upon juvenile elements from the Eo2 and WS8 bonebeds. Sutures and points of contact between bones are marked in black. Scale bar equals 10 cm; scale is calibrated with the dentary of CEUM 9758. (B) Life restoration of the head of Eolambia by Lukas Panzarin. Abbreviations: an, angular; d, dentary; f, frontal; j, jugal; l, lacrimal; mx, maxilla; na, nasal; pd, predentary; pmx, premaxilla; po, postorbital; prf, prefrontal; q, quadrate; qj, quadratojugal; sa, surangular; sq, squamosal.

Morphological variation in the Deltapodus ibericus holotype trackway from the CT-1 tracksite. (a) False-color depth maps and interpretative outline drawings of a selection of manus–pes sets within the trackway. Note the variation in manus (from crescent, kidney to semicircular shapes) and pes (reversed delta, semirectangular, and oval shapes) tracks depending on the manus–pes set. Note also that some manus are overprinted by the pes. (b) Mediotype of the pes impressions based on 4 specimens with a mean footprint length of 0.48 m. Note that the morphology of the posterior part of the print is slightly biased (more quadrangular) because this area in track 1CA17p is broken. (c) Mediotype of the manus impressions based on 2 specimens with a mean footprint width of 0.37 m. (d–f) Pictures of a selection of the best-preserved tracks (manus–pes set 1CA23, pes 1CA17p and manus 1CA3m). The false color depth maps were generated with the software CloudCompare (https://www.cloudcompare.org/) and the mediotypes with the software DigTrace (https://www.digtrace.co.uk/).
