Back in March 2025, the Foundation for Portland Public Schools announced the opening of the Rosenthal Museum of Natural History at Portland High School. Thanks to a generous donation from Sam Rosenthal, PHS Class of 1971, the museum features an impressive collection of fossils, including ammonites, ancient alligator jaws, massive megalodon teeth, and dinosaur bones.

The museum is open to Portland Public Schools educators and students, enhancing biology instruction and offering hands-on learning experiences. It also welcomes scheduled visits from K–12 classes across the district. Recently, East End Community School second graders had the chance to explore the collection firsthand, sparking curiosity and excitement about natural history among young learners.
