Fossilized fish bones sat beside plastic shark teeth, printed by modern 3-D printers Sunday in Smith Hall on the University of Alabama campus. The UA Museum of Natural History hosted the first Science Sunday of the year to demonstrate 3-D printing technology for the public. The free event also featured fossil displays, a guest lecture and the unveiling of a skull from Xiphactinus audax, a late-Cretaceous predatory fish. Allie Sorlie, education outreach coordinator for the museum, said the event was designed as a fun, family-friendly program. “This Science Sunday was all about 3-D printing and how it can be used in paleontology,” Sorlie said. “We had crafts, coloring and other activities for kids, including making a Xiphactinus kite.” Sources: The Tuscaloosa News, The Crimson White
