holotype

Photograph of the holotype (USNM 538127) vertebra of the sauropod Dzharatitanus (Averianov & Sues, 2021). A is the posterior view; B is the right lateral view; C is the anterior view. Scale bar equals 10 centimetres.

Holotype right pes of Vespersaurus paranaensis gen. et sp. nov. (MPCO.V 0065d1). (a) Distal end of metatarsal II-IV in dorsal view. (b) Distal part of digit II in lateral view. (c) Distal part of digit IV in lateral view. (d) Entire foot as preserved in lateral view. Anatomical abbreviations: ed, extensor depression; fd, flexor depression; lcp, lateral collateral pit; mc, lateral crest; plg, proximolateral groove; vg, vertical groove; vlg, ventral lateral groove; vm, ventral margin.

Holotype specimen of the anurognathid pterosaur Sinomacrops

Skeletal reconstruction of Siamraptor suwati. Cranial elements were scaled to fit in with the holotype (surangular). Human size = 1.8 m. Scale bar = 1 m. Human silhouette has been added to the original image.

Skeletal reconstruction of Ahshislepelta minor, a small ankylosaur from the Late Cretaceous Kirtland Formation of New Mexico. While originally recovered as an ankylosaurid related to Gastonia, later analyses favored a nodosaurid position which this is based on. Based on the holotype SMP VP-1930, consisting of fragmentary shoulder, forelimb, and vertebral elements as well as several osteoderms. Unknown material filled in using Niobrarasaurus, Pawpawsaurus, Silvisaurus, Sauropelta, and Borealopelta. Total length is approximately 4.9 m through the centra. Notes: Osteoderm placement somewhat speculative, not all osteoderms and vertebral fragments are figured. References: Burns & Sullivan, 2011.

Holotype skull and mandible of the anhanguerid Ferrodraco (A), holotype skull and mandible of the anhanguerid Mythunga (B), and holotype mandible of the targaryendraconian Aussiedraco (C).

Ferrodraco lentoni gen. et sp. nov. holotype specimen AODF 876. All preserved elements were photographed and scaled to the same size, then articulated where possible. These were then used as the basis for the scaling of the skeletal reconstruction, the missing parts of which were based on the skeletal reconstruction of Tropeognathus mesembrinus by Mark Witton. Scale bar = 50 mm.
