Text Appearing Before Image: Managing Editor Katie Mosher Senior Editors Ann Green Pam Smith L. Noble Circulation Manager Sandra Harris The North Carolina Sea Grant College Program is a federal/state program that promotes the wise use of our coastal and marine resources through research, extension and education. It joined the National Sea Grant College Network in 1970 as an institutional program. Six years later, it was designated a Sea Grant College. Today, North Carolina Sea Grant supports several research projects, a 12-member extension program and a communications staff. Ron Hodson is director. The program is funded by the U.S. Department of Commerce's National Oceanic and Atmospheric Administration and the state through the University of North Carolina.

North Carolina ® COASTAL TIDINGS You've Got to Have Heart Rer Text Appearing After Image: ^member Wiilo, a dinosaur featured in 'Take a Walk on the Wild Side" in the spring edition of Coastwatch? Well, Willo has gone on to interna- tional acclaim since scientists have published their findings: Willo is the world's first I J * Jim Page known dinosaur specimen with a fossilized heart! Scientists from North Carolina State University and the N.C. Museum of Natural Sciences published the historic findings in the journal Science, just weeks after Coastwatch went to press. Until the findings were published, Coastwatch could only hint at the importance of the Thescelosaurus, a 66-million-year-old herbivore. According to Dale Russell, NC State paleontologist and the museum's senior research curator, computer-enhanced images of Willo's heart suggest it is a four- chamber, double-pump heart with a single systemic aorta — more like the heart of a mammal or bird than a reptile. The findings suggest that the dinosaur's circulatory system was more advanced than that of modern-day reptiles, and supports the hypothesis that dinosaurs were warm-blooded, Russell says. Willo is about the size of a short-legged pony. He was discovered in 1993 in South Dakota and was acquired by the museum in 1996. Since then, the fossil specimen has undergone exhaustive, high-tech probes and analysis to unravel its biological mysteries. On permanent display in the new museum in Raleigh, Willo's grapefruit-sized, reddish brown clump of a heart, is clearly visible within its partially exposed chest. Images of the fossil, a video and further information are available on the Web at www.dinoheart.org, a site jointly maintained by the museum and the university. - P.S. In the Next Issue of Coastwatch How are coastal communities grappling with major water issues — quality, quantity and wastewater disposal? Pam Smith will examine the science and the politics of this critical environmental challenge. The peak summer season keeps coastal fishing piers bustling with first-time tourists and veteran anglers alike. Ann Green checks in on several piers — and on the debate surrounding proposals for saltwater fishing licenses.
