Skeletal reconstruction of Maraapunisaurus fragillimus, with restored dorsal vertebra in posterior view. Scaled from Lavocatisaurus, Agustinia, Comahuesaurus, Amazonsaurus, & other basal rebbachisaurids, with neck extended allometrically following Stevens & Parrish (2006). Human silhouette is myself.
Crato Formation pterosaur diversity – the dawn of Araripe pterosaur era. We emphasize that the coexistence of the taxa is merely illustrative, since the lack of geological context for most pterosaur fossils from the Araripe Basin prevents a precise inference of contemporaneity.

Dzharacursor is an ornithomimid theropod dinosaur from the Late Cretaceous of what is now Uzbekistan. Ornithomimids like Dzharacursor are known for their long legs lending to a cursorial, or running, lifestyle. They had a feathered covering, and were likely omnivorous, or possibly herbivorous. Adult Dzharacursor could grow to approximately 3.5 m in length.
Restoration of Bagualosaurus agudoensis. (The female may not be to scale, the total length of Bagualosaurus in the original publication is given in a graph with a scale of 20 cm, and can be inferred to be about 1.6 m. See File:Bagualosaurus Scale.svg for a closer comparison)
Ahvaytum is a saturnaliid sauropodomorph from the Late Triassic of what is now Wyoming. It is the oldest known dinosaur from the northern continent of Laurasia, challenging previous hypotheses of dinosaur origins and dispersal. Typical of basal dinosaurs from the Triassic, Ahvaytum was a small slender biped, reaching about 1 m in body length.

Huashanosaurus is a basal sauropod dinosaur that lived from the Early to Middle Jurassic periods of what is now China. It was a long-necked herbivore which still exhibited many basal traits of the earlier sauropodomorphs, while transitioning to obligate quardupedality. Huashanosaurus grew to approximately 12 m in length, and weighed around 10 t.
Fujianvenator is an anchiornithid avialan from the Late Jurassic of China, whose discovery gave important insight to the evolution of birds. It had proportionately long legs, with the tibia twice the length of the femur. This suggests it may have been a strong runner, and possibly had a terrestrial or wading lifestyle. Fujianvenator was a small dinosaur, weighing about 640 g. As an avialan, it was almost certainly covered in feathers, though it does not seem likely to have been capable of flight.

The skeleton of Strutbiomimus altus, a small dinosaur from the BeliyRiver series (Cretaceous), Red Deer River, Alberta, Canada, now regarded as ofapproximately the same age as the Judith River series. The unique feature ofthe skull is the total absence of teeth, with a size of skull one-third larger thanthe ostrich and a length of body of about fifteen feet. The position of the skeletonis decidedly that of the opisthotonos which may be regarded as an indication ofdisease. (After Osborn).

The holotype and only known specimen of the hauffiopterygian leptonectid, Xiphodracon goldencapensis (ROM VP52596) from Golden Cap, between Charmouth and Seatown, Dorset, UK. The skeleton is exposed in ventrolateral view. The skull has been fully prepared free of matrix whereas most of the skeleton is still in matrix. The left (upper) forefin has been prepared so that it is three-dimensionally preserved and projects upwards. Scale bar represents 20 cm.

Dinosaur Park Formation in Dinosaur Provincial Park, Alberta
The distictive banding of the Morrison Formation, a group of rock layers that occur throughout Dinosaur National Monument. The formation originated as muds and sands laid down by ancient rivers, and some of its outcrops have been found to contain 150-million-year-old dinosaur fossils like those found at the monument's Dinosaur Quarry.
