Life Onto Land: The Devonian

You’ve likely heard of the Jurassic and the Cretaceous, but do you know about the Devonian? With its incredible diversity of terrestrial life, this fascinating period in geological history — hundreds of millions of years before the age of the dinosaurs — was pivotal in shaping the world as we know it today. All vertebrates living on land, including humans, stem from the remarkable creatures that began the move onto land in the Devonian Period. 

Life Onto Land: The Devonian centers around the Academy’s internationally celebrated paleontological research and the incredible discovery of Tiktaalik roseae. Unearthed in 2004 on Ellesmere Island in the Canadian Arctic territory of Nunavut, this transitional fossil has been critical in piecing together a picture of how fins became limbs — or, of how terrestrial, limbed vertebrates arose from aquatic, lobe-finned ancestors. 

This new exhibition features the original holotype specimen of Tiktaalik roseae and a newly commissioned Tiktaalik model by Tyler Keillor. See enchanting drawings by Spanish artist Aina Bestard, breathtaking footage of Arctic and Antarctic research sites and the vivid scientific illustrations of Scott Rawlins. Experience the stunning plant and animal fossils collected from Devonian rock found here in Pennsylvania and around the world.  

Life Onto Land reveals the diverse marine, freshwater swamp and terrestrial ecosystems of this period, as well as the amazing scientific discoveries of the Academy’s team of paleontologists who continue to contribute to our understanding of this transformational time in our planet’s history. 

All exhibits are included with the purchase of a general admission ticket.

Academy scientists spend their days exploring the natural world, caring for our collection of 19 million scientific specimens and working to solve the most pressing environmental issues facing our communities today. Make a gift to support their work.
