THE Museum of Yale College has recently received the greater portion of the skeleton of a huge reptile, which proves to ue one of the lDost remarkable animals yet discovered. It was found on the eastern flank of the Rocky Mountains, in beds which I bave regarded as corresponding nearly to the Wealden of Europe, and which may be classed as upper J massic. 'l'be remains are well preserved, but are embedded in so hard a matrix that considemble time and lauor will be required to prepare them for a… 

On the presence of Allosaurus fragilis (Theropoda: Carnosauria) in the Upper Jurassic of Portugal: first evidence of an intercontinental dinosaur species

The species Allosaurus fragilis, from the Morrison Formation of North America (Kimmeridgian–Tithonian, Upper Jurassic), is one of the best known members of the Theropoda, the group including all

Regnosaurus northamptoni, a stegosaurian dinosaur from the Lower Cretaceous of southern England

Abstract The type specimen of Regnosaurus northamptoni Mantell, a partial right mandible, is redescribed and compared with a wide variety of dinosaurian taxa. We suggest that Regnosaurusis not an

THE name Dinosauria was proposed by Prof. Richard Owen (i), in a paper on " British Fossil Reptiles," read before the ninth meeting of the British Association, at Birmingham in i839. In this order

Stegosauria: a historical review of the body fossil record and phylogenetic relationships

A new phylogeny, which includes all valid stegosaurian taxa, largely agrees with previous studies and shows the European Dacentrurinae was sister taxon to Stegosaurus.

A probable stegosaurian track from the Late Jurassic of Poland

Elusive tracks of stegosaurs have been long searched for by ichno− logists, and various purported stegosaur imprints have recently been reported. A fragmentary trackway of a large, quadrupedal

The Postcranial Skeleton of an Exceptionally Complete Individual of the Plated Dinosaur Stegosaurus stenops (Dinosauria: Thyreophora) from the Upper Jurassic Morrison Formation of Wyoming, U.S.A.

Several aspects of its morphology indicate the individual was not fully skeletally mature at the time of death, corroborating a previous histological study and enabling additional comparisons with other stegosaurian dinosaurs.

Reassessment of a Historical Collection of Sauropod Dinosaurs from the Northern Morrison Formation of Wyoming, with Implications for Sauropod Biogeography

ABSTRACT The Upper Jurassic Morrison Formation of the western United States preserves one of the best-known Mesozoic paleoecosystems worldwide. The formation crops out over an area from New Mexico

New evidence of shared dinosaur across Upper Jurassic Proto-North Atlantic: Stegosaurus from Portugal

More than one century after its original description by Marsh in 1877, we report in this paper the first uncontroversial evidence of a member of the genus Stegosaurus out of North America. The

A review of the Late Jurassic stegosaurs (Dinosauria, Stegosauria) from the People's Republic of China

This taxonomic revision significantly reduces known stegosaurian diversity worldwide, and shows that the Chinese diversity was similar to that of Europe and North America in the Upper Jurassic.

Dacentrurine stegosaurs (Dinosauria): A new specimen of Miragaia longicollum from the Late Jurassic of Portugal resolves taxonomical validity and shows the occurrence of the clade in North America

A largely complete specimen of M. longicollum is described, confirming this to be the first known dacentrurine stegosaur in America, coherent with the hypothesis of an ephemeral land bridge between North America and Iberia that allowed faunal exchange.
