Abstract We describe the integumentary anatomy of titanosaur sauropod embryos from the Auca Mahuevo nesting site. Natural (calcitic) casts of the skin show the non-imbricating, tuberculate scales (i.e., tubercles) typical of other non-avian dinosaurs. However, a variety of scale patterns previously unknown for the skin of these animals is reported. The observed integumentary patterns include ground tubercles, large and elongated tubercles, parallel rows of large tubercles, tubercles in rosette… 

New Occurrences of Dinosaur Skin of Two Types (Sauropoda? and Dinosauria Indet.) from the Late Jurassic of North America (Mygatt-Moore Quarry, Morrison Formation)

Sauropod skin was first found by S. H. Beckles in 1852 (Czerkas, 1997) in direct association with a limb bone of Pelorosaurus. Very well preserved sauropod skin has been re ported recently from

Newly detected data from Haestasaurus and review of sauropod skin morphology suggests Early Jurassic origin of skin papillae

Discovered in 1852, the scaly skin belonging to Haestasaurus becklesii was the first to be described in any non-avian dinosaur. Accordingly, it has played a crucial role in the reconstruction of

The exquisitely preserved integument of Psittacosaurus and the scaly skin of ceratopsian dinosaurs

The Frankfurt specimen of the early-branching ceratopsian dinosaur Psittacosaurus is remarkable for the exquisite preservation of squamous (scaly) skin and other soft tissues that cover almost its

Titanosaur Osteoderms from the Upper Cretaceous of Lo Hueco (Spain) and Their Implications on the Armor of Laurasian Titanosaurs

TLDR
An eliptic Fourier analysis on the outline of complete specimens from this morphotype reveals that they truly are part of a morphological cline; and the existence of a consistent correlation between the outline and the morphology of the bulb.

Dermal Armor Histology of Saltasaurus loricatus, an Upper Cretaceous Sauropod Dinosaur from Northwest Argentina

The first unambiguous evidence of the presence of osteoderms in sauropod dinosaurs came from the discovery of Saltasaurus loricatus, a titanosaur from the Upper Cretaceous of Argentina. The dermal

Articulated bone sets of manus and pedes of Camarasaurus (Sauropoda, Dinosauria)

Skeletons of sauropods are rarely found with fore and hind feet, and until now, only one specimen of this clade has been reported with all four autopodia preserved complete and articulated. This

Anatomy of Juravenator starki (Theropoda: Coelurosauria) from the Late Jurassic of Germany

: We provide a detailed study of the morphology of the holotype of Juravenator starki from the Late Jurassic of the Solnhofen area of southern Germany. The incompletely ossified surface of multiple

Exceptionally preserved juvenile megalosauroid theropod dinosaur with filamentous integument from the Late Jurassic of Germany

TLDR
Sciurumimus albersdoerferi represents the phylogenetically most basal theropod that preserves direct evidence for feathers and helps close the gap between feathers reported in coelurosaurian theropods and filaments in ornithischians, further supporting the homology of these structures.

Sauropod dinosaur embryos from the Late Cretaceous of Patagonia

TLDR
The first known unequivocal embryonic remains of sauropod dinosaurs—the only known non-avian dinosaur embryos from Gondwana—are described from a nesting ground in the Upper Cretaceous stage of Patagonia, Argentina and it is proposed that these specimens belong to the same sauroPod species.

Eggs of titanosaurid sauropods from the Upper Cretaceous of Auca Mahuevo (Argentina)

The last of the dinosaur titans: a new sauropod from Madagascar

TLDR
A total-evidence phylogenetic analysis supports a close relationship between brachiosaurids and titanosaurs (Titanosauriformes), and the inclusion of cranial data from Rapetosaurus lays to rest questions concerning the phylogeny of the enigmatic Mongolian genera Nemegtosaurus and Quaesitosaurus.

Early Evolution and Higher-Level Phylogeny of Sauropod Dinosaurs

TLDR
The cladistic analysis presented here focuses on higher-level relationships among sauropods, and identifies Neosauropoda as a new taxon that includes Haplocanthosaurus, Camarasaurus, and Titanosauriformes.

Discovery of dermal spines reveals a new look for sauropod dinosaurs

The smooth, quasi-elephantine form of the huge, long-necked sauropods is a familiar image widely repeated in both scientific and general literature. Recent discovery of fossilized sauropod

TLDR
The specimen differs from the holotype of Aeolosaurus rionegrinus Powell, 1986 in the length of the prezigapophyses, relative position of the postzigapophysicales, and radius and ischium morphology.
