This specimen, a male, was collected from San Nicholas Island, California. It was made available to The University of Texas High-Resolution X-ray CT Facility for scanning courtesy of Dr. Blaire Van Valkenburgh of the Department of Ecology and Evolutionary Biology, University of California, Los Angeles. Funding for scanning and image processing was provided by Dr. Van Valkenburgh and by a National Science Foundation Digital Libraries Initiative grant to Dr. Timothy Rowe of The University of Texas at Austin. The California sea lion is one of several carnivorans included in ongoing research of respiratory turbinates by Dr. Van Valkenburgh.
