Joggins Fossil Cliffs
World Heritage fossil site preserving a 310-million-year-old rainforest ecosystem.
The Joggins Fossil Cliffs are a coastal exposure of Carboniferous (Coal Age) rocks located in Joggins, a rural community in western Cumberland County, Nova Scotia, Canada. They are renowned for preserving a 310-million-year-old rainforest ecosystem and for yielding some of the earliest known tetrapod fossils, including the earliest known sauropsid reptile, Hylonomus lyelli. The cliffs were inscribed on the UNESCO World Heritage List on July 7, 2008.

Lore & Background
The Joggins Fossil Cliffs have attracted geologists since the late 1820s, with early observations by Abraham Gesner, Richard Brown, Thomas Jackson, and Francis Alger. In 1835, a party from Williams College, Massachusetts, became the first student group to study the site. The cliffs gained international fame through visits in 1842 and 1852 by Charles Lyell, founder of modern geology, who later proclaimed the exposure 'the finest example in the world' of Coal Age rocks and fossils in his 1843 Travels in North America. The fossil record at Joggins is not cited in Charles Darwin's On the Origin of Species, though Darwin referenced Lyell's work on Joggins in correspondence. There is no historical evidence that Joggins fossils were specifically mentioned in the Great Oxford Debate of 1860 between Bishop Wilberforce and Thomas Huxley.
Reader's Guide
The Joggins Fossil Cliffs are significant for their unparalleled record of a Pennsylvanian tropical rainforest ecosystem, including in situ fossilized trees and trackways of the giant arthropod Arthropleura. The cliffs have yielded Hylonomus lyelli, the earliest known sauropsid reptile and Nova Scotia's provincial fossil, as well as Protoclepsydrops, an even earlier synapsid. The site also preserves evidence of the Carboniferous Rainforest Collapse, a mass extinction event. Daily tidal erosion continually exposes new fossils, making Joggins one of the easiest places in the world to find early Pennsylvanian coal fossils. The Joggins Fossil Centre, a seasonal museum, displays the geological history, scientific discoveries, and the impact of coal mining on the community. The cliffs remain a key location for ongoing research, coordinated by sedimentologist Martin Gibling of Dalhousie University.
Did You Know?
- Hylonomus lyelli, discovered at Joggins, is the earliest known sauropsid reptile and was named the provincial fossil of Nova Scotia in 2002.
- The cliffs preserve trackways made by the giant arthropod Arthropleura and tree-like lycopodiophyte Sigillaria preserved in situ.
Frequently Asked Questions
What are the Joggins Fossil Cliffs?
They are a stretch of coastal rock face in the rural community of Joggins, Nova Scotia, where Carboniferous-era sediment layers have been worn away by the sea to expose a 310-million-year-old rainforest frozen in stone. The site lies in western Cumberland County, Canada.
Why are the Joggins Fossil Cliffs important?
The cliffs preserve an entire Late Carboniferous ecosystem in remarkable detail, from giant Sigillaria tree trunks to the trackways of massive Arthropleura. They also yield some of the oldest tetrapod fossils ever documented, offering a rare snapshot of life's earliest steps onto land.
What famous fossils were found at Joggins?
The most celebrated specimen is Hylonomus lyelli, recognized as the earliest known sauropsid reptile. Another landmark find is Protoclepsydrops, one of the oldest synapsids, alongside the sprawling Arthropleura trackways left by ancient millipede-like creatures.
When did Joggins Fossil Cliffs become a UNESCO World Heritage Site?
UNESCO inscribed the site on its World Heritage List on July 7, 2008. The designation recognized the outstanding universal value of its Pennsylvanian (Late Carboniferous) fossil record.
Which 19th-century geologists studied the Joggins cliffs?
Charles Lyell, Sir William Dawson, Abraham Gesner, and William Logan all conducted fieldwork at the site during the 1800s. Their observations helped establish Joggins as one of the most significant fossil localities in the world.
