Interstate Through Time: The Fossil Discoveries of I-71

Primary tabs

Over 50 years ago, construction began on Interstate 71 through Cleveland’s west side. As the dozers hit the ground, they uncovered a hidden treasure: giant armored fish skulls and mummified sharks buried for 360 million years.

Half a century later, I-71’s fossils continue to surprise and enlighten!
