Holotype of Jaculinykus yaruui gen. et sp. nov. (MPC-D 100/209). (A) Photograph of the specimen. (B) Explanatory drawing of (A). Highlighted areas refer to the indication of the skeletal elements; skull in green, tail in grey, pectoral girdle and forelimbs in red, pelvis and hind limbs in purple. (C) Reconstruction of Jaculinykus yaruui gen. et sp. nov. Grey areas are missing parts.

Reconstruction of the skull of Lagenanectes richterae in right lateral view. Only the anterior part of the skull and lower jaw is preserved in the type and only known specimen. The posterior parts are reconstructed based on the related genus Libonectes.

Holotype specimen (CRILAR-Pv 151) of Huayracursor jaguensis, a long-necked dinosaur that lived approximately 230 million years ago, placed in approximate anatomical articulation.

An overview of the known fossil material of Tyrannomimus fukuiensis. Fossil specimens shown in are not in the same scale. The bar is scaled for the paratype (FPDM-V-10295). The holotype (FPDM-V-11333) and paratype in are colored in red and blue, respectively. The right femur in is mirrored from the left one (FPDM-V-11338).

Terminocavus sealeyi holotype NMMNH P-27468 parietal. Dorsal (A) and ventral (B) views. Paired ep1 are deflected dorsally. em, median embayment of the posterior bar; ep, epiparietal loci numbered by hypothesized position (no epiossifications are fused to this specimen); f, parietal fenestra; lb, lateral bar; L-lr/R-lr, Left/Right lateral rami of the posterior bar; mb, median bar; te, tapering lateral edges of the median bar. Scalebar = 10 cm. Reconstruction adapted from Lehman (1998).

Fossil specimen in the Natural History Museum of Utah, Salt Lake City, Utah, USA. Photography was permitted in the museum without restriction.

The holotype specimen of the extinct pterosaur Ceoptera, NHMUK PV R 37110

Holotype specimen of the anurognathid pterosaur Sinomacrops

Vertebrae of the holotype specimen of Padillasaurus leivaensis.

Fossil specimen of Liaoningosaurus paradoxus on display at the Beijing Museum of Natural History.

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.
