Nasutoceratops skull model in the Arizona Museum of Natural History
Qunkasaura is a titanosaurian sauropod dinosaur that lived approximately 75 million years ago in the Late Cretaceous of what is now Spain. Specifically, it is a saltasaurid titanosaur, and its discovery marks the first instance of two distinct lineages of this group present in the same locality. In the Late Cretaceous, Europe was a large archipelago, and the coexistence of these differing lineages indicates that saltasaurids arrived in the Iberian Peninsula much later than other groups of dinosaurs.

(A) View of the original downside in the field and the best preserved side as it experienced the least disruption by scavenging sharks. (B) Detail of midbody region showing the large gastroliths that settled downwards onto the inside of the right, dorsal ribs. This region was hit by the excavator bucket with the partial loss of ribs and an unknown number of gastroliths. Fortuitously, the broken blocks hosting gastroliths can be removed and their contents inspected from several sides. Scalebar is 10 cm.

Reconstructed skull of Paranthodon africanus (Broom, 1912) Nopcsa, 1929. This skull reconstruction is based upon the figures in Galton & Coombs (1981), and Raven & Maidment (2018) with the rear of the skull and lower jaw based upon Stegosaurus stenops USNM 4934. White material is known, based upon BMNH 47337, the holotype front portion of jaw, BMNH 47338, a matrix including some impressions and teeth, and BMNH 49992, including teeth. Scale bar is 10cm.

His researches, and those of several authors since then,supplementing and confirming or disproving those of the manyobservers made during the preceding seventy years, have finallydetermined almost perfectly the complete structure of the moretypical ichthyosaurs, enabling us to infer not a little as to theirhabits and distribution in the old Jurassic oceans. Within thepast few years the discoveries of Professor J. C. Merriam of Cali-fornia have likewise added greatly to our knowledge of the earlierichthyosaurs. It may now truthfully be said that of no group ofextinct reptiles do we have a more complete and satisfactory knowl-edge than of the ichthyosaurs.

They have, as an order, so isolated a position,are so widely separated from all other reptiles in structure, that theyhave long been a puzzle to paleontologists. Like the whales andother cetaceans among mammals, we know the ichthyosaurs wellin the plenitude of their power and the fulness of their development,but have yet only an imperfect knowledge of their earlier history,and none whatever of their earliest. However, as will be seenfarther on, the recent discoveries by Merriam have shed much lighton some of the stages of their evolution. So nearly perfectly wereall the later ichthyosaurs adapted to their life in the water that itwas believed by nearly all paleontologists until about a score of years ICHTHYOSAURIA 3 ago that they had desc Note About Images Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original work.
