Devonian stromatoporoids (reef-building, calcifying sea sponges) from the Miette carbonate buildup in Jasper National Park

Well-preserved stromatoporoid (Devonian calcifying sea sponge); vertical structures are called 'pillars', while small chambers are called 'galleries'.

Devonian reef buildup formed by stromatoporoids (calcifying sea sponges), with morphologies ranging from bulbous to branching (Amphipora).
