Fig. 2 in Diversity and taxonomy of the Late Triassic sauropodomorphs (Saurischia, Sauropodomorpha) stored in the Palaeontological Collection of Tübingen, Germany, historically referred to Plateosaurus

Fig. 2. Stratigraphic section of the middle and upper Keuper of the Germanic Basin as exposed in BadenWürttemberg (right), and Bavaria and Saxony-Anhalt (both on the left). The numbers represent the findings described in the text. Zanclodon laevis (Plieninger, 1846) is restricted to an archosauromorph of uncertain affinities from the Ladinian (Erfurt Formation). Sauropodomorphs appear towards the upper part of the middle Keuper, which may be of late Carnian or early Norian age. The black silhouettes represent specimens not currently classified as Plateosaurus Meyer, 1837.

Fig. 3. Timeline showing changes in the taxonomic placement of the specimens of early-diverging sauropodomorphs considered to be Plateosaurus Meyer, 1837 from 1900 to 2004. This timeline considers only papers discussing taxonomy and papers describing and naming new species. Lines indicate continuity or change in specimen composition of species across revisions. Arrows outside the timeline indicate that the taxa were named before 1900 and / or are still valid after 2004. When more lines depart from one node, part of the specimens included in that species were referred to as different species. Lines converging in one node indicate that the specimens were lumped together into the species in the node. Stars at the end of a line indicate that in the taxonomic revision, the name became either a nomen dubium or a nomen nudum. Lines continuing after this point indicate that the specimens were referred to the new node. This timeline does not include specimens removed from the genus Plateosaurus, namely Efraasia (von Huene, 1907–1908), Ruehleia Galton, 2001, Camelotia Galton, 1985 and Tuebingosaurus Regalado Fernández & Werneburg, 2022. The green lines correspond to species that have been synonymized with Pl. trossingensis Fraas, 1913, and the blue lines correspond to those that have been synonymized with Pl. gracilis (von Huene, 1905). The orange-red lines refer to species removed from Sauropodomorpha Huene, 1932 altogether. Changes after 2004 are discussed in the text.

Fig. 1. Map showing the city of Tübingen, Baden-Württemberg, in the centre of the localities of the specimens described in this paper. The second map places Baden-Württemberg within Germany. The timeline shows the chronology in which the specimens were first excavated but not described. The date of the excavation of 'Zanclodon' is the only one that is not certain (see Results – Mid-19th century). Map data: Google, GeoBasis-DE / BKG.

Fig. 15 in New skulls of the basal sauropodomorph Plateosaurus trossingensis from Frick, Switzerland: Is there more than one species?

Fig. 15. Overview over the distribution of variable features occurring in two or more skulls (category II and III characters; CII and CIII, respectively) in the 18 most complete skulls of Plateosaurus examined herein. The prevalent character state is marked with "a", while the rarer state is marked with "b". Intermediate states are marked with "c". No correlations of feature combinations that might indicate distinct species are evident, and the observed pattern is consistent with intraspecific variability.

Fig. 2 in New skulls of the basal sauropodomorph Plateosaurus trossingensis from Frick, Switzerland: Is there more than one species?

Fig. 2. Bone shortening due to plastic deformation. A. Compression may lead to substantial shortening along the axis of deformation. Note that no widening occurs. B. Right humerus of MSF 12.3 in posterior (B1) and medial (B2) views, showing extreme anteroposterior compression especially of the distal end. Despite this compression, the bone is not significantly widened in posterior view when compared with the relatively undeformed humerus of GPIT-PV-30785.

Spurwing Island; arrow indicates the fossil locality at the Spurwing East Palaeosol site. D. Sedimentology of the Spurwing East Palaeosol site. E. Articulated hind limb of Musankwa sanyatiensis gen. et sp. nov. (NHMZ 2521) as discovered in situ. F.
