Fig. 1. 3D in A morganucodontan mammaliaform from the Upper Jurassic Morrison Formation, Utah, USA

Fig. 1. 3D surface renderings from CT data of the morganucodontan mammaliaform Cifellilestes ciscoensis gen. et sp. nov. (OMNH 80538, holotype), from the Cisco Mammal Quarry, Utah, USA, Upper Jurassic Morrison Formation. A. Right skull fragment in lateral (A1), medial (A2), ventral (A3), and dorsal (A4) views. B.

Fig. 7 in A morganucodontan mammaliaform from the Upper Jurassic Morrison Formation, Utah, USA

Fig. 7. Hypothetical molar occlusal wear facet pattern in P5–M1 of Cifellilestes ciscoensis gen. et sp. nov. (B, OMNH 69352), with illustration of a lower molar modified from Morganucodon watsoni Kühne, 1949 (A, m2, UMZC_Eo.CR.1, reversed). Corresponding colors on upper and lower teeth indicate matching wear facets. The occlusal pattern of C. ciscoensis is similar to M. watsoni in that the protoconid (also referred to as cusp a) of the lower molars occludes between the upper molar paracone (also referred to as cusp A) and cusp B, carving a prominent groove between the two cusps. This also results in contact to the next mesial tooth, due to the size of the protoconid. The paracone occludes between the protoconid and metaconid (also referred to as cusp c). Modified after Jäger et al. (2019).

Fig. 6. Comparative 3D in A morganucodontan mammaliaform from the Upper Jurassic Morrison Formation, Utah, USA

Fig. 6. Comparative 3D renderings of upper dentition of the morganucodontans Morganucodon watsoni Kühne, 1949 (A, UMZC Eo.CR.1, reversed; Lower Jurassic fissure fills, Wales, UK), Storchodon cingulatus Martin, Averianov, Jäger, Schwermann, and Wings, 2019 (B, NLMH 105654; Upper Jurassic Süntel Formation, Germany), Megazostrodon rudnerae Crompton and Jenkins, 1968 (C, NHMUK PV M 26407; Lower Jurassic Stormberg Group, Lesotho), and Cifellilestes ciscoensis gen. et sp. nov. (D, OMNH 80538, holotype; Upper Jurassic Morrison Formation, USA), in lingual (A1–D1) and occlusal (A2–D2) views. White lines indicate the premolar–molar boundary (all taxa except Storchodon, which is known by only a single molar). This boundary is marked by a tall-crowned ultimate premolar with much lower flanking cusps followed by a first molar that is comparatively lower crowned with less height difference between the main cusps. Note imbrication of the molars in C. ciscoensis gen. et sp. nov. (D2) and distal molars in Mo. watsoni (A2), a feature absent in Me. rudnerae (C2).

Fig. 7 in First palaeoscolecid from the Cambrian (Drumian, Miaolingian) Marjum Formation of western Utah, USA

Fig. 7. Palaeogeographic distribution of Cambrian palaeoscolecids in Laurentia. For each occurrence, the numbers in parentheses refer to the number of palaeoscolecid specimens known (left) and the number of species they represent (right). The Rosella Formation Lagerstätte is positioned between the Lagerstätten of the American Great Basin and those of the Canadian Rockies, because the Cassiar terrane was located near present-day Idaho in the Cambrian, and subsequently migrated more than 2000 km to the North (Pope and Sears 1997). Abbreviations: Fm., Formation; Sh., Shale. Background map adapted from Cocks and Torsvik (2011).
