TL;DR: The Oretaceous Dinosaurs from the Laramie are still under ill-vestigation, and many new points in their structure have recently been brought to light as mentioned in this paper, some of which are here placed on record for the first time, and taken in connection with those previously made known by the writer, indicate that the genus is a very distinct one, worthy to be called a suborder, wInch may be termed the Ger·atojJsia.
Abstract: THE gigantic horned Dinosaurs from the Laramie, which have already been described by the writer, in this Journal,* are still under illvestigation, and many new points in their structure have recently been brought to light. Some of these are here placed on record for the first time, and taken in connection with those previously made known by the writer, indicate that the gro~l p is a very distinct one, worthy to be called a sub-order, wInch may be termed the Ger·atojJsia. Some of the main characters of this gl'OllP are shown in the specimens figured in the accompanying plates, and others will be fully represented in the illustrations of the memoir now in preparation. The new fmms described make it still more evident that the Oretaceous Dinosaurs, of which so little has hitherto been known, are quite as remarkable as their allies from the Jurassic.

Abstract: The holotype of the upper Campanian ankylosaur Antarctopelta oliveroi n. gen., n. sp., from James Ross Island, Antarctica, is described. Diagnostic characters include short cervicals (centrum length about 70% of the centrum height), distal caudal vertebrae with transverse processes well developed (centrum width including the transverse processes exceeds 30% of the posterior articulation width) and dorsoventrally depressed, and the presence of smooth, sub-circular osteoderms, surrounded by a mosaic of smaller polygonal osteoderms with a rugose surface texture and tiny, button-like ossicles. While a number of features, such as relatively large teeth with respect to the mandible and the presence of an asymmetrical cingulum, suggest an affinity with the Nodosauridae, others such as the dorsoventrally depressed morphology of the distal caudal vertebrae and, especially, the presence of ossified tendons on their ventral side, characterize the Ankylosauridae. This uncertainty impedes evaluation of the paleobiogeographi cal significance of this new species of dinosaur. RESUME
