Skeletal composite of the recently reclassified halszkaraptorine dinosaurs Hulsanpes perlei, featuring the holotype specimen ZPAL MgD-I/173 which is an immature individual. It was found in the Barun Goyot Formation of Mongolia in 1970 and described in 1982 by Halszka Osmólska. The genus was first classified as a dromaeosaurid taxon with unresolved affinities,[1] but in 2017 with the description of the peculiar genus Halszkaraptor, the Halszkaraptorinae was coined and Hulsanpes identified as a member. The holotype consist of a right metatarsus composed by II, III and IV metatarsals with three phalanges, and a partial right braincase fragment.[2]
Life restoration of Angolatitan based on the holotype and the skeletal diagram by Javifel (Felipe Martínez). Coloration based in grey-breasted francolin (Pternistis rufopictus) [Head and Neck] and the Desert elephant (Loxodonta africana) [Body].
Skeletal diagram of Spicomellus afer showing known fossil material of the holotype (NHMUK PV R37412) and referred (USMBA 5–84) specimens. Scale bar=1 m. Note: Many osteoderms of various morphologies are preserved in the referred specimen. However, the placement of these elements is unclear in most cases. Maidment et al. (2025) provided a speculative reconstruction of Spicomellus, most of which is followed here. As such, there are many other interpretations that are equally valid and the one presented here is not intended to represent the 'most likely one.' Ossified tendons preserved on the tail 'handle' have been omitted to avoid obscuring the vertebrae.

Skeletal diagram of Hudiesaurus sinojapanorum. The vertebra is based on figures and measurements from Dong (1997), gotten from an [https://svpow.com/2009/05/05/hudiesaurus-redux/ SV-POW post). The silhouette is based on a Mamenchisaurus skeletal by Bricksmashtv. Human silhouette from File:Silhouette of man standing and facing forward.svg. The exact positioning of the vertebra is unknown, and could profoundly influence the overall length of the animal, so it should be taken with a grain of salt. Here it is reconstructed with a length of 27m.

Probrachylophosaurus bergei gen. et sp. nov. skull reconstruction. (A) Preserved skull elements of MOR 2919, left lateral view. Predentary not included due to its poor preservation and diagenetic compression. (B) Outline of skull reconstruction, left lateral view. The outline accounts for diagenetic distortion of the posterior braincase, but otherwise does not correct for distortion of skull elements. Outlined regions where left skull material was not preserved are based on right bones when available. Regions with neither left nor right material preserved are hypothesized reconstructions based on Brachylophosaurus canadensis skulls. (C) Braincase with left nasal crest, dorsal view. (D) Outline of braincase reconstruction with nasal crest, dorsal view. Reconstruction accounts for diagenetic lateral compression and distortion of posterior braincase.

Skeletal reconstruction of Austrocheirus isasii, a strange theropod from the Late Cretaceous Cerro Fortaleza Formation of Argentina. This particular reconstruction is based on a Berthasaurid position following Hendrickx et al., but the relationships of this species are still under debate. Based on the holotype MMPM-PV 10003, consisting of fragmentary hindlimb, forelimb, and vertebral elements. Unknown material filled in using Berthasaura, Gualicho, Deltadromeus, and vespersaurus. Total length is approximately 5.8 m through the centra. Notes: Ulna is mirrored from the right side. Location of the pedal phalanxes and vertebral fragments is speculative. Measurements are unavailable for the manual ungual and fourth metatarsal, so their size is based on other elements and comparison with other specimens.

Scale and skeletal diagram for Gojirasaurus quayi, holotype specimen UCM 47221. Outline and proportions roughly based on Coelophysis, Dilophosaurus, and Zupaysaurus, scaled to the 5.5 meter length estimate published by Carpenter (1997). Apart from the speculative gastralia dimensions, all bones are based on illustrations published by Carpenter (1997) and photos published by Griffin (2019) and the UCM fossil vertebrate collection (https://fossilvertebratesandtraces.colorado.edu/index.php/Detail/vertebrate/54346/subsite/vertebrate#). Right pubis and right scapula are depicted in medial view, other bones are in lateral view.
