Olfactory acuity in theropods: palaeobiological and evolutionary implications
- Darla K. Zelenitsky, François Therrien, Y. Kobayashi
- Biology, Medicine
- Proceedings of the Royal Society B: Biological…
- 22 February 2009
This research presents the first quantitative evaluation of the olfactory acuity in extinct theropod dinosaurs. Olfactory ratios (i.e. the ratio of the greatest diameter of the olfactory bulb to the… Expand
Feathered Non-Avian Dinosaurs from North America Provide Insight into Wing Origins

An oviraptosaurian specimen (Dinosauria, Theropoda) from an Upper Cretaceous formation in China retains a pair of shelled eggs in the pelvis, providing direct evidence that oviraptorosaurian… Expand
Parataxonomic classification of ornithoid eggshell fragments from the Oldman Formation (Judith River Group; Upper Cretaceous), southern Alberta
- Darla K. Zelenitsky, L. Hills, P. J. Currie
- Geology
- 1 December 1996
Examination of a large number of eggshell fragments collected from the Oldman Formation of southern Alberta reveals a greater ootaxonomic diversity than is known from complete eggs or clutches. Three… Expand
Eggshell Taphonomy at Modern Gull Colonies and a Dinosaur Clutch Site
- J. Hayward, Darla K. Zelenitsky, D. L. Smith, Darlene M. Zaft, Jere K. Clayburn
- Biology
- 1 August 2000
Abstract Eggshell taphonomy often is acknowledged to be worthy of investigation, but few studies have examined factors influencing eggshell preservation. In this study eggshell weathering,… Expand
Evolution of olfaction in non-avian theropod dinosaurs and birds
- Darla K. Zelenitsky, François Therrien, R. Ridgely, A. McGee, L. Witmer
- Biology, Medicine
- Proceedings of the Royal Society B: Biological…
- 22 December 2011
Little is known about the olfactory capabilities of extinct basal (non-neornithine) birds or the evolutionary changes in olfaction that occurred from non-avian theropods through modern birds.… Expand
Normal and pathological eggshells of Spheroolithus albertensis, oosp. nov., from the Oldman Formation (Judith River Group, late Campanian), southern Alberta
- Darla K. Zelenitsky, L. Hills
- Biology
- 16 April 1997
ABSTRACT Eggshell fragments collected from the Oldman Formation, southern Alberta, are described as Spheroolithus albertensis, oosp. nov. This oospecies exhibits a spheroolithid microstructure,… Expand
FIRST RECORD OF ELONGATOOLITHID THEROPOD EGGSHELL FROM NORTH AMERICA: THE ASIAN OOGENUS MACROELONGATOOLITHUS FROM THE LOWER CRETACEOUS OF UTAH
- Darla K. Zelenitsky, K. Carpenter, P. J. Currie
- Biology
- 17 April 2000
Abstract Theropod eggshell is identified for the first time from the Lower Cretaceous of North America. Eggshell microstructure and variability in ornamentation and thickness of this material is… Expand
New eggshell of ratite morphotype with predation marks from the Eocene of Colorado
- K. F. Hirsch, A. J. Kihm, Darla K. Zelenitsky
- Biology
- 19 June 1997
ABSTRACT A large number of eggshell fragments from a single locality of the lower Eocene (?Wa5-Wa6 biochron) DeBeque Formation of northwestern Colorado are interpreted as representing a single,… Expand
PHYLOGENETIC ANALYSIS OF REPRODUCTIVE TRAITS OF MANIRAPTORAN THEROPODS AND ITS IMPLICATIONS FOR EGG PARATAXONOMY
- Darla K. Zelenitsky, François Therrien
- Biology
- 1 July 2008
A phylogenetic analysis of reproductive and oological (egg) traits of theropod taxa allows determination of the sequence in which these traits evolved in Theropoda. Our results indicate that several… Expand
