Variable Levels Of Atmospheric Oxygen Do Not Affect Microanatomy And Limb Bone Geometry In Alligator Mississippiensis, Susan Lee Lujan
Variable Levels Of Atmospheric Oxygen Do Not Affect Microanatomy And Limb Bone Geometry In Alligator Mississippiensis, Susan Lee Lujan
Theses Digitization Project
Striking changes in atmospheric oxygen levels have occured since the beginning of the Phanerozic 542 million years ago. Alligators belong to a clade of vertebrates with a long evolutionary history spanning much of this variability in atmospheric oxygen. An investigation into the effects of hypoxia and hyperoxia on skeletal growth and physiology in alligators may help to reconstruct the life history of archosaurs, explain patterns in the fossil record, and broaden our understanding of the processes underlying long term success of this clade.

Postcranial Description And Reconstruction Of The Varanodontine Varanopid Aerosaurus Wellesi (Synapsida: Eupelycosauria), Valerie Ann Pelletier
Theses Digitization Project
The postcranial skeleton of the varanopid synapsid aerosaurus wellesi is reconstructed based on several specimens including partly articulated material of an apparently fully adult specimen. Comparisons are made with other known varanopid taxa, reaffirming its position as a basal varanondontine.
