This specimen has formed the basis for the concept of Anchisaurus, the first basal sauropodomorph genus from the U.S.A. and still the best represented from there since it was illustrated by Marsh (1892, 1893), and of M. polyzelus since it is illustrated by Galton (1976). Expand
Osteología embrionaria de saurópodos titanosaurios de Neuquén (Argentina): aspectos ontogenéticos y evolutivos
Several of the characters, including the snout with “stepped” anterior margin and the infratemporal fenestra extending ventrally to the orbit support the identification of the embryos as eusauropods. Expand
A review of the reptile and amphibian assemblages from the Stormberg of southern Africa
The Molteno, Elliot, and Clarens formations comprise the continental Stormberg Group of the Karoo Basin of South Africa and Lesotho. The Molteno Formation contains a well preserved macroandExpand
The promise of taphonomy as a nomothetic discipline: taphonomic bias in two dinosaur-bearing faunas in North America1
The fossil record of dinosaurs is a rich, if biased, one with nearly complete skeletons, partial skeletons, and isolated parts found in diverse, well-studied faunal assemblages around the world. Am...
The Late Jurassic Sauropod Dinosaur ‘Morosaurus’ Agilis Marsh, 1889 Reexamined and Reinterpreted as a Dicraeosaurid
ABSTRACT The holotypic materials of the sauropod ‘Morosaurus' agilis—a partial skull, proatlases, and first three cervical vertebrae—have been a taxonomic and phylogenetic mystery since their initialExpand
Modernist architecture in Barcelona reveals a new trace fossil from the Miocene of Montjuïc (NE Spain)
A new ichnotaxon, Lapillitubus montjuichensis n. i gen. n. isp., is described from the middle Miocene (Serravallian) of Montjuic mountain (Barcelona, northeastern Spain). This ichnotaxon consists ofExpand
Paleobiology of Titanosaurs: Reproduction, Development, Histology, Pneumaticity, Locomotion and Neuroanatomy from the South American Fossil Record
Saltasaurines in particular show evidence of postcranial skeletal pneumaticity in both axial and appendicular skeleton, providing clues about soft tissue anatomy and the structure of the respiratory system. Expand
The Braincase Assigned to the Ornithopod Dinosaur Uteodon McDonald, 2011, Reassigned to Dryosaurus Marsh, 1894: Implications for Iguanodontian Morphology and Taxonomy
ABSTRACT The braincase from the Upper Jurassic (lower Tithonian) Morrison Formation of the Carnegie Quarry at Dinosaur National Monument (Utah), which was assigned to the ankylopollexianExpand
Growth Record and Histological Variation in the Dorsal Ribs of Camarasaurus sp. (Sauropoda)
This study provides the most complete growth record for a sauropod so far, and indicates that it took 40 years for Camarasaurus sp. Expand
