[1][2][4] The book and the film, which aired on April 18, 1968, tell the story of a boy who finds an enormous egg laid by a hen that hatches a baby Triceratops.

The statue is modeled after one of nine dinosaurs of different species that Jonas designed and constructed for the Sinclair Oil Corporation's pavilion at the 1964 New York World's Fair in consultation with paleontologists Barnum Brown and Edwin H. Colbert of the American Museum of Natural History in New York City and John Ostrom of the Peabody Museum of Natural History at Yale University.

[2] Zoo staff also created a garden exhibit for Uncle Beazley near Lemur Island with funding from a gift from a Director's Circle donor in memory of her parents.

[10][11] NBC's telecast of The Enormous Egg also featured five smaller Triceratops models that Louis Paul Jonas had created to represent the dinosaur during its youth.

[5][12] In 1979, George Heinemann, the telecast's producer, donated the models to Pittsfield's Berkshire Museum, a Smithsonian Affiliate organization in Western Massachusetts.
