Neuroanatomy of the spinosaurid Irritator challengeri (Dinosauria: Theropoda) indicates potential adaptations for piscivory

Schade, Marco ; Rauhut, Oliver W. M. ; Evers, Serjoscha W.

In: Scientific Reports, 2020, vol. 10, no. 1, p. 9259

Spinosauridae, a theropod group characterized by elongated snouts, conical teeth, enlarged forelimbs, and often elongated neural spines, show evidence for semiaquatic adaptations and piscivory. It is currently debated if these animals represent terrestrial carnivores with adaptations for a piscivorous diet, or if they largely lived and foraged in aquatic habitats. The holotype of Irritator...

A description of the skull of eubaena cephalica (hay, 1904) and new insights into the cranial circulation and innervation of baenid turtles

Rollot, Yann ; Lyson, Tyler R. ; Joyce, Walter G.

In: Journal of Vertebrate Paleontology, 2018, vol. 38, no. 3, p. e1474886

The internal carotid system has played an important role in the systematics of fossil turtles, including baenids. A new, almost perfectly preserved specimen of Eubaena cephalica provides an opportunity to explore for the first time the cranial circulation and innervation of this taxon using CT (computed tomography) scans. We here document that the skull possesses a well-developed, branching...

Wax and Plaster Memories : Children in Elite and non-Elite Strategies

Dasen, Véronique

In: Children, Memory, and Family Identity in Roman Culture, 2010, p. 109-145

Various strategies were adopted to preserve and honour familial memory in ancient Rome. Most famous are portraits of ancestors, "imagines maiorum", depicting office holders, which marked aristocratic habits of the late Roman Republic. Literary and archaeological sources reveal a range of alternative "imagines" in non-elite circles of later periods which may refer to these prestige objects and...

Cranial ontogenetic variation in early saurischians and the role of heterochrony in the diversification of predatory dinosaurs

Foth​, Christian ; Hedrick, Brandon P. ; Ezcurra, Martin D.

In: PeerJ, 2016, vol. 4, p. e1589

Non-avian saurischian skulls underwent at least 165 million years of evolution and shapes varied from elongated skulls, such as in the theropod Coelophysis, to short and box-shaped skulls, such as in the sauropod Camarasaurus. A number of factors have long been considered to drive skull shape, including phylogeny, dietary preferences and functional constraints. However, heterochrony is...

New insights into the lifestyle of Allosaurus (Dinosauria: Theropoda) based on another specimen with multiple pathologies

Foth​, Christian ; Evers, Serjoscha W. ; Pabst, Ben ; Mateus, Octávio ; Flisch, Alexander ; Patthey, Mike ; Rauhut, Oliver W.M.

In: PeerJ, 2015, vol. 3, p. e940

Adult large-bodied theropods are often found with numerous pathologies. A large, almost complete, probably adult Allosaurus specimen from the Howe Stephens Quarry, Morrison Formation (Late Kimmeridgian–Early Tithonian), Wyoming, exhibits multiple pathologies. Pathologic bones include the left dentary, two cervical vertebrae, one cervical and several dorsal ribs, the left scapula, the left...
