Central America on Pangaea: Not Missing, Just Formed Later

Central America and Pangaea

Central America is not "missing" from reconstructions of the supercontinent Pangaea—it simply did not exist in its current form at that time.

Geological Context

Pangaea existed roughly 335 to 175 million years ago. The landmass that would become Central America—the isthmus connecting North and South America—formed much later, primarily through volcanic activity and tectonic uplift along the Caribbean Plate boundary, beginning around 15–3 million years ago.

Modern Central America

Today, Central America comprises seven countries: Belize, Costa Rica, El Salvador, Guatemala, Honduras, Nicaragua, and Panama. On a Pangaea map, this region appears as part of the western edge of the North American landmass, adjacent to the proto-Pacific ocean, but the distinct isthmus and volcanic arc are absent.

So, Central America isn't missing—it's a geologically young feature that emerged long after Pangaea broke apart.
