Morris Arboretum & Gardens Goes Mesozoic!

See our new exhibitions Plants in the Age of Dinosaurs and Garden Railway: Dinos!

Philadelphia, PA—It’s a summer of dinos…and plants…at Morris Arboretum & Gardens! Travel back in time with two new exhibitions: Plants in the Age of Dinosaurs and Garden Railway: Dinos!, running from Saturday, May 25, 2024, through Monday, September 30, 2024. Learn more at

Plants in the Age of Dinosaurs is a new self-guided exhibition where visitors will learn more about the plants in our collection with roots that go back to prehistoric times. The Mesozoic Era was a time of great geologic and biological transition, with some of the hottest temperatures on Earth. As the climate changed, plants changed, too! Visitors can learn more about non-flowering plants like conifers, which dominated the landscape for millions of years, and about flowering plants that fostered part of the huge boom in numbers and types of dinosaurs.

There is also a brand-new dinosaur exhibition in the Garden Railway, Garden Railway: Dinos! Visitors will enjoy a spectacular display of Mesozoic Era creatures including Tyrannosaurus rexTriceratops and Velociraptor—all made from natural materials such as bark, nuts, leaves, seed pods, and twigs—nestled within one of the largest outdoor model train displays in the United States. With 15 different rail lines running along a third of a mile of trackage, the Garden Railway will delight and amaze visitors of all ages.

In addition, there will be dino-themed events and programs from May through September, including a pop-up paleontologist’s cottage featuring hands-on “dig stations,” dino story times, Fossil Fridays, and much more!
