Androgynous rex - the utility of chevrons for determining the sex of crocodilians and non-avian dinosaursGregory M Erickson
Department of Biological Science, Florida State University, Tallahassee, FL 32306 1100 USA
Zoology (Jena) 108:277-86. 2005..Study of well-preserved tyrannosaurid dinosaurs in museum collections showed nearly invariant chevron positioning like that seen in crocodilians. This suggests the usefulness of chevron anatomy for sexing dinosaurs is tenuous...
Complex dental structure and wear biomechanics in hadrosaurid dinosaursGregory M Erickson
Department of Biological Science, Florida State University, Tallahassee, FL 32306 4295, USA
Science 338:98-101. 2012..Three-dimensional wear models incorporating fossilized wear properties reveal how these tissues interacted for grinding and ecological specialization...
Insights into the ecology and evolutionary success of crocodilians revealed through bite-force and tooth-pressure experimentationGregory M Erickson
Department of Biological Science, Florida State University, Tallahassee, Florida, United States of America
PLoS ONE 7:e31781. 2012..How these factors relate to biomechanical performance during feeding and their relevance to crocodilian evolutionary success are not known...- Was dinosaurian physiology inherited by birds? Reconciling slow growth in archaeopteryxGregory M Erickson
Department of Biological Science, Florida State University, Tallahassee, Florida, USA
PLoS ONE 4:e7390. 2009..This hypothesis predicts that the long bones in these birds formed using rapidly growing, well-vascularized woven tissue typical of non-avialan dinosaurs... - A life table for Psittacosaurus lujiatunensis: initial insights into ornithischian dinosaur population biologyGregory M Erickson
Department of Biological Science, Florida State University, Tallahassee, Florida, USA
Anat Rec (Hoboken) 292:1514-21. 2009..This may reflect increased physiological demands and/or predation exposure associated with reproduction. Collectively these findings suggest that most nonavian dinosaurs may have had a similar life history strategy... - Growth patterns in brooding dinosaurs reveals the timing of sexual maturity in non-avian dinosaurs and genesis of the avian conditionGregory M Erickson
Department of Biological Science, Florida State University, Tallahassee, FL 32306 1100, USA
Biol Lett 3:558-61. 2007.... - Dinosaurian growth patterns and rapid avian growth ratesG M Erickson
Department of Biological Science and College of Medicine, Florida State University, Tallahassee, Florida 32306 1100, USA
Nature 412:429-33. 2001..Non-avian dinosaurs did not attain rates like those of altricial birds. Avian growth rates were attained in a stepwise fashion after birds diverged from theropod ancestors in the Jurassic period... - Tyrannosaur life tables: an example of nonavian dinosaur population biologyGregory M Erickson
Department of Biological Science, Florida State University, Tallahassee, FL 32306, USA
Science 313:213-7. 2006..Factors such as predation and entrance into the breeding population may have influenced tyrannosaur survivorship. This survivorship pattern can explain the rarity of juvenile specimens in museum collections... - Gigantism and comparative life-history parameters of tyrannosaurid dinosaursGregory M Erickson
Department of Biological Science, Florida State University, Tallahassee, Florida 32306 1100, USA
Nature 430:772-5. 2004..T. rex had a maximal growth rate of 2.1 kg d(-1), reached skeletal maturity in two decades and lived for up to 28 years. T. rex's great stature was primarily attained by accelerating growth rates beyond that of its closest relatives... - Evolution of the biomechanical material properties of the femurGregory M Erickson
Department of Integrative Biology, University of California Berkeley, Berkeley, CA, USA
Anat Rec 268:115-24. 2002..Major locomotory challenges to femora during vertebrate evolution were almost solely accomplished by modifications of element size and shape... - A basal tyrannosauroid dinosaur from the Late Jurassic of ChinaXing Xu
Institute of Vertebrate Paleontology and Paleoanthropology, Beijing 100044, China
Nature 439:715-8. 2006.... - A basal dromaeosaurid and size evolution preceding avian flightAlan H Turner
Division of Paleontology, American Museum of Natural History, Central Park West at 79th Street, New York, NY 10024 5192, USA
Science 317:1378-81. 2007..Thus, change in theropod body size leading to flight's origin was not unidirectional... - Definitive fossil evidence for the extant avian radiation in the CretaceousJulia A Clarke
Department of Marine, Earth and Atmospheric Sciences, North Carolina State University, Campus Box 8208, Raleigh, North Carolina 27695, USA
Nature 433:305-8. 2005..A minimum of five divergences within Aves before the K/T boundary are inferred from the placement of Vegavis; at least duck, chicken and ratite bird relatives were coextant with non-avian dinosaurs... - Prey choice and cannibalistic behaviour in the theropod CoelophysisSterling J Nesbitt
Division of Paleontology, American Museum of Natural History, New York, NY 10024 5192, USA
Biol Lett 2:611-4. 2006..These findings suggest that this taxon is not cannibalistic and bring into question the commonality of this behaviour among non-avian dinosaurs...
