A 90-million-year-old fossil fish, currently on display at the Perot Museum of Nature and Science in Dallas, turns out to be a new species. Research conducted by Kenshu Shimada, Ph.D., professor at DePaul University and research associate of the Sternberg Museum, reveals the 5.5-foot-long fossil fish to possess a tuna-like body with a unique 'hook-shaped sail' on its back. The fish's new species name, Pentanogmius fritschi, is in honor of local amateur collector Joseph Fritsch.
