Travel planning often begins with destinations, accommodations, and activities. Yet in Costa Rica, travel becomes far more meaningful when visitors understand the deep history beneath the landscape.
Beyond rainforests, volcanoes, and protected reserves, Costa Rica holds evidence of a prehistoric past — one that includes mastodons and giant ground sloths that once roamed the region during the Pleistocene epoch.
A recent discovery in Cartago brought that ancient history vividly back into the present.
Fossil discovery in Cartago
The discovery of fossil remains of a mastodon and a giant ground sloth in Cartago began when a citizen reported the possible presence of ancient bones on private property.
After receiving the alert, specialists from the National Museum of Costa Rica conducted a technical inspection of the site. Initial analysis confirmed that the remains belonged to megafauna from the Pleistocene period — animals that lived thousands of years ago, long before Costa Rica’s modern ecosystems took their current form.
Given the magnitude of the discovery, authorities instructed the National Museum to begin designing and establishing a permanent exhibition hall dedicated to the national paleontological collection.
This decision reflects the scientific and cultural importance of the find.
Mastodon tusk found in Cartago
The recovery process was complex. The site, located near a river in Cartago, presented challenging terrain that required careful and specialized excavation techniques.
An interdisciplinary team of 12 professionals — including geologists, archaeologists, and biologists — carried out the rescue operation.
To date, 13 interventions have been conducted, resulting in the recovery of 49 fossil pieces. Among them:
These findings confirm that Costa Rica once supported large prehistoric mammals in regions that today are characterized by rich biodiversity and agricultural landscapes.
Prehistoric giant ground sloth reconstruction
During the Pleistocene epoch, the climate was cooler and ecosystems differed from today’s tropical forests. Mastodons and giant ground sloths moved through environments that have since transformed through climate change, geological activity, and human settlement.
Understanding this prehistoric layer adds perspective to modern travel.
The forests visitors explore today are part of a long environmental timeline — one shaped by extinction, adaptation, and regeneration.
Costa Rica’s biodiversity did not emerge overnight. It is the result of thousands of years of ecological transformation.
Costa Rica is internationally recognized for its conservation model, protecting nearly 30% of its territory through national parks and reserves.
When viewed in the context of prehistoric extinctions, conservation takes on deeper meaning.
The disappearance of megafauna like mastodons and giant ground sloths reminds us that ecosystems can change permanently. Today’s environmental policies aim to prevent further irreversible loss and preserve what remains.
For travelers, this awareness transforms the experience:
Travel becomes less about observation and more about understanding.
Landscape near fossil site in Cartago
Costa Rica offers more than scenic beauty. It offers context.
The discovery in Cartago highlights the country’s role not only as a biodiversity hotspot but also as a site of paleontological significance. For academic groups, students, and curious travelers, this adds an additional dimension to exploration.
Understanding the land’s deep past enriches the journey.
It connects landscapes to time.
