Histology of ankylosaur osteoderms: implications for systematics and function

Journal of Vertebrate Paleontology, 2004
ABSTRACT Here, we provide a comparative survey of the histology of postcranial dermal-armor osteoderms of ankylosaurs, including material of polacanthids (Polacanthus foxii, Gastonia sp.), ankylosaurids (e.g., Saichania chulsanensis, Pinacosaurus grangeri, Ankylosauridae indet.), and nodosaurids (e.g., Struthiosaurus austriacus, Nodosauridae indet ...

New ankylosaur (Thyreophora, ornithischia) remains from the Upper Cretaceous of Patagonia

Journal of South American Earth Sciences, 2019
Abstract Fossil evidences of the presence of ankylosaurian dinosaurs in Gondwana are scarce but consistent, being found in Antarctica, Oceania and South America. In spite that there are no nominated species in South America, the ankylosaur fossil record has increased in the last years.

Ankylosaur systematics: example using Panoplosaurus and Edmontonia (Ankylosauria: Nodosauridae)

Journal of Paleontology, 1990
A partial nodosaurid ankylosaur skeleton, consisting primarily of the ilia, hindlimbs, posterior dorsal armor, plus partial forelimb elements and additional armor, was recovered from the marine Point Loma Formation, late Campanian age, north of San Diego, California.

External and internal structure of ankylosaur (Dinosauria; Ornithischia) osteoderms

2010
Here I assess the use of osteoderms in systematics with comparative material from fossil and extant tetrapod taxa. Putative differences among three groups (ankylosaurid, nodosaurid, and polacanthid) were evaluated. Archosaur osteoderms have cortices surrounding a cancellous core.

A Nodosaurid Ankylosaur (Dinosauria: Ornithischia) from the Lower Cretaceous of Texas

Journal of Vertebrate Paleontology, 1995
ABSTRACT A partial nodosaurid ankylosaur skeleton from Lower Cretaceous littoral deposits of Texas represents a new genus and species, Texasetes pleurohalio. It is distinguished by a prong-like scapular spine that is directed toward the innermost point of the glenoid, development of a small prespinous fossa, and retention of a splint-like fourth ...

Ankylosaurs from the Price River Quarries, Cedar Mountain Formation (Lower Cretaceous), east-central Utah

Journal of Vertebrate Paleontology, 2008
ABSTRACT A new large nodosaurid ankylosaur, Peloroplites cedrimontanus, is described from a partial skull and postcranial skeleton found at the PR-2 Quarry located at the base of the Mussentuchit Member of the Cedar Mountain Formation in central Utah.

A juvenile ankylosaur referable to the genusEuoplocephalus(Reptilia, Ornithischia)

Journal of Vertebrate Paleontology, 1986
ABSTRACT A specimen of a juvenile ankylosaur from the Upper Cretaceous Horseshoe Canyon Formation (Red Deer River, Alberta, Canada) includes a nearly complete pes, the first reported for the genus Euoplocephalus. Differences between juvenile and adult ankylosaurs are qualitatively similar to differences reported for juvenile and adult stegosaurs.
