Natalia Rybczynski

Natalia Rybczynski, Ph.D., is a Canadian paleobiologist, professor and researcher.

She is a research scientist with the Canadian Museum of Nature and holds a professorship at Carleton University in Ottawa. Her doctorate was obtained at Duke University and her main interests are evolutionary functional morphology, particularly at the polar climes.^[1]

Rybczynski is notable for having discovered a previously unknown carnivorous arctic mammal, a proto-seal, which represents a "missing link" between land-dwelling mammals and modern day ocean-going seals. Puijila darwini was discovered in 2007 on Devon Island in the Canadian arctic. Discovery of this specimen was announced in the journal Nature in April 2009. She has also contributed to the understanding of the biomechanics of Suminia, a primitive mammal thought to exhibit early evidence of teeth and jaw structure specialized for chewing.^[2]

She is the niece of writer and architect Witold Rybczynski.
