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.

Nyasasaurus is a basal dinosauromorph that may be the earliest known dinosaur. It was a small bipedal animal at about 2-3 m in length. Nyasasaurus is difficult to classify due to inconclusive fossil evidence, but if it is a true dinosaur, it pushes the dinosaur lineage back about 12 million years to the Middle Triassic.

Sidersaura is a rebbachisaurid sauropod dinosaur from the Late Cretaceous of Argentina. Rebbachisaurids are the last known dipldocoids, and lived alongside the titanosaurs until fairly late in the Cretaceous before disappearing from the fossil record, presumably going extinct. They have long tails and relatively short necks, by sauropod standards. Sidersaura one of the most recent rebbachisaurids yet found, living in the Cenomanian–Turonian ages of the Late Cretaceous. It was large for a rebbachisaurid, growing to about 20 m in length.
