Acantilados fosilíferos de Joggins

The Joggins Fossil Cliffs are a palaeontological site of 689 hectares on the coast of Nova Scotia, on the Cumberland basin, at the head of the Bay of Fundy. Its 14.7 kilometres of sea cliffs, rock platforms and beach were inscribed on the World Heritage List in 2008 and are known as the "Galápagos of the Carboniferous" for the abundance and quality of their fossils. They constitute the thickest and most complete record in the world of Pennsylvanian strata, between 318 and 303 million years old, and preserve the finest known archive of terrestrial life from that period.

What is exceptional is that everything is in its original position. The fossil trunks of lycopsids are preserved upright, exactly as they grew in the equatorial forest that then covered this latitude, alongside the tracks and remains of the animals that lived in it. The site brings together three superimposed ecosystems: estuarine bay, floodplain forest and forested alluvial plain subject to fire, with freshwater pools. The tides of the Bay of Fundy, the greatest on the planet at almost 17 metres of range, renew the base of the cliff twice a day and continuously expose fresh material, which makes the site one that regenerates itself.

Joggins is a foundational place in palaeontology. Charles Lyell, father of modern geology, visited the cliffs in the middle of the nineteenth century and described the forest of fossilised trees as the most astonishing phenomenon he had seen. In 1852, together with William Dawson, he found inside a hollow lepidodendron stump the first tetrapod amphibian and fossil land snails, named Dendrerpeton acadianum and Dendropupa vetusta; Darwin drew those finds into his argument. In 1859 Dawson discovered there Hylonomus lyelli, the oldest known reptile and ancestor of dinosaurs, birds and lizards. Traces of giant invertebrates have also been preserved, among them those of a millipede-like arthropod some two metres long. Today the Joggins Fossil Centre, built on the cliff itself, runs the interpretation and the guided visits.
