Uncovered skeleton of Brachauchenius sp. VL from the late Barremian Formacio´n Paja of Loma La Cabrera, Villa de Leyva area, in dorsal view. The far posterior part (ischia, tail) and the right hind limb are not preserved.

Life restoration of the Triassic ichthyosaur Callawayia neoscapularis. Three specimens of this ichthyosaur are known, the holotype, ROM 41993, and two referred specimens, TMP 94.380.11 and 94.382.2. The skull is primarily based on ROM 41993, cross-checked against TMP 94.380.11 and TMP 94.382.2. The vertebral column is based primarily on TMP 94.382.2 as it is the most complete of these specimens, while the ribs were based on ROM 41993. The forelimbs were mainly based on those of ROM 41993, with TMP 94.380.11 used to determine their breadth. The hindlimbs were based on TMP 94.380.11, especially the more complete right hindlimb. ROM 41993 was cross-scaled with TMP 94.380.11 by the dimensions of the forelimb epipodials, which produced similar vertebral dimensions. The two TMP specimens were cross-scaled based on femoral length, also producing similar vertebral dimensions. Nicholls & Manabe (2001) stated that no wedge-shaped caudal centra supporting a tailbend were found and that there was no evidence of a bend being present, though considered that they might have existed in the gap in the preserved caudals. Since various other Triassic ichthyosaurs have since been found to have tail bends, one was illustrated here. A modest downturn of roughly 15° was illustrated, comparable to that in Guanlingsaurus, and the location of the bend within the gap in the preserved vertebrae matches well with the location of the bend in Guizhouichthyosaurus.

Duck-billed dinosaurs at the Royal Ontario Museum. A Maiasaura skeleton is visible on the foreground, with two Maiasaura juveniles at the foot of the skeletal mount. On the background, flushing with the wall, there's the two-dimensional mount of a Gryposaurus specimen. The unidentified skull of another duck-billed dinosaur is visible on the low right corner of the photograph.
