That is a simplification, of course -- the process took millions of years and involved anatomical changes so subtle they are visible only in cross-sections of fossilized bone. But the evidence is here, locked in alternating layers of sandstone and shale that have been eroding into Chaleur Bay for millennia. Miguasha National Park, designated a UNESCO World Heritage Site in 1999, preserves one of the most remarkable fossil assemblages on Earth: a window into the Upper Devonian period, roughly 370 million years ago, when the ancestors of all terrestrial vertebrates were still figuring out how to breathe air.

Miguasha National Park: The Cliffs That Rewrote Biology

Fri, 13 Mar 2026 00:00:00 GMT

Photo credit Neumeier, CC BY-SA 3.0. The Escuminac Formation runs along the coast near the town of Carleton-sur-Mer, its exposed strata forming a timeline written in sediment. These beds are approximately 370 million years old, deposited when this region lay near the equator in a warm, shallow estuary teeming with p...

Photo credit Gachepi, CC BY-SA 3.0. The fossils at Miguasha document more than just fish with ambitious fins. The site has yielded specimens of Spermasporites, thought to be among the oldest seed plant genera on Earth -- evidence that the botanical revolution was underway at the same time vertebrates were transitio...

Miguasha National Park: A Mi'kmaq Shoreline

Fri, 13 Mar 2026 00:00:00 GMT

Photo credit Neumeier, CC BY-SA 3.0. The name Miguasha derives from the Mi'kmaq language, often interpreted as referring to a red-colored earth -- fitting for a landscape where iron-stained sediments streak the cliff faces with rust and ochre. The Mi'kmaq inhabited this coastline long before European naturalists rec...

Miguasha National Park: Where Deep Time Meets the Bay

Fri, 13 Mar 2026 00:00:00 GMT

Photo credit paléon, CC BY-SA 4.0. The setting adds a dimension that photographs cannot capture. The Escuminac Formation faces Chaleur Bay, and at low tide the wave-cut platform exposes bedding surfaces where fossil fish lie as they died, their bodies oriented by ancient currents. Birch, aspen, and fir forests cro...
