The early evolution of the Tyrannosauridae in Asia

Journal of Paleontology, 1999
An isolated premaxillary tooth of a tyrannosaurid from the Lower Cretaceous section of the Tetori Group, Central Honshu, Japan, complements Siamotyrannus, which is based upon an incomplete postcranium for existence of tyrannosaurids in the Early Cretaceous of Asia.

A new study of the brain of the predatory dinosaur Tarbosaurus bataar (Theropoda, Tyrannosauridae) [PDF]

Paleontological Journal, 2007
The brain morphology and the topography of the cranial nerves on an endocranial mold of the theropod dinosaur Tarbosaurus bataar (Tyrannosauridae) are examined. The brain of this dinosaur was constructed based on the reptile archetype, with a well-developed specialized olfactory analyzer.

Cranial osteology of a juvenile specimen ofTarbosaurus bataar(Theropoda, Tyrannosauridae) from the Nemegt Formation (Upper Cretaceous) of Bugin Tsav, Mongolia

Journal of Vertebrate Paleontology, 2011
ABSTRACT A juvenile skull of the tyrannosaurid Tarbosaurus bataar found in the Bugjn Tsav locality in the Mongolian Gobi Desert is described. With a total length of 290 mm, the present specimen represents one of the smallest skulls known for this species.

Assessing Social Behaviour, Ontogenetic Change and Taxonomic status in a Juvenile Gorgosaurus libratus (Dinosauria; Theropoda; Tyrannosauridae): A multidisciplinary analysis [PDF]

, 2015
The sparseness of the fossil record and the subjectivity of interpreting behaviour from morphological and taphonomic evidence have impeded studies on the behaviour of juvenile theropod dinosaurs. Most evidence for social behaviour in juvenile dinosaurs comes from multi individual bone beds or parent dinosaurs preserved while brooding on eggs or young ...

Quantifying tooth variation within a single population ofAlbertosaurus sarcophagus(Theropoda: Tyrannosauridae) and implications for identifying isolated teeth of tyrannosauridsThis article is one of a series of papers published in this Special Issue on the themeAlbertosaurus.

Canadian Journal of Earth Sciences, 2010
Documenting variation in theropod dinosaurs is usually hindered by the lack of a large sample size and specimens representing several ontogenetic stages. Here, variation within 140 disassociated and seven in situ tyrannosaur teeth from the Upper Cretaceous (lower Maastrichtian) monodominant Albertosaurus sarcophagus (Theropoda: Tyrannosauridae) bonebed

Introduction to Evolutionary Teratology, with an Application to the Forelimbs of Tyrannosauridae and Carnotaurinae (Dinosauria: Theropoda)

Evolutionary Biology, 2015
Conceptualisation of evolution requires new inclusions, as evidenced by contributions brought by evolutionary developmental biology—the evo-devo connection. Integration of teratology in an evolutionary framework fits in this continuity. It highlights the production of developmental anomalies (more or less drastic) over evolutionary times, which become ...

The phylogenetic position of the Tyrannosauridae: implications for theropod systematics

Journal of Paleontology, 1994
Tyrannosaurids are a well-supported clade of very large predatory dinosaurs of Late Cretaceous Asiamerica. Traditional dinosaurian systematics place these animals within the infraorder Carnosauria with the other large theropods (allosaurids, megalosaurids).
