The American Museum of Natural History is holding its annual Identification Day on Saturday, March 23, from noon to 4 p.m. Members of the public can bring in rocks, fossils, and other items to be examined by scientists. In the past, people have brought in such unusual items as a 3,000-year-old hand ax found in a Staten Island backyard and a dinosaur footprint discovered at a garage sale. Museum scientists suggest bringing as much information as you have for an item, and keeping any plants in a zip-lock bag. They ask that people do not bring live or recently deceased animals to the event. Everyone who brings an item to the museum, which has a new exhibit titled “T.Rex: The Ultimate Predator, ” will get a cast of a T-Rex tooth from the museum’s collection. Entrance to Identification Day is free with museum admission. By Lisa L. Colangelo email@example.com @lisalcolangelo Lisa joined amNewYork as a staff writer in 2017.
