A sinkhole on a Mexican highway has exposed a water-filled cave teaming with fossils of sea life and rock formations dating as far back as 2.5 million years.
Cave explorers are using the large crevasse between Playa del Carmen and Tulum, Quintana Roo, to enter the 60-meter-long cave, where they also uncovered living creatures, including crustaceans.
The Mexico Daily News said specialists are now working on a topographic map of the cave.
Robert Rojo, a biologist and cave explorer said the cave gets its water from the Caribbean Sea.
Rojo also said filling in the sinkhole and closing off the entrance would be tantamount to “ecocide,” a total destruction of the natural environment.
Rojo and other experts are working on a detailed report of the cave, with recommendations on how to preserve it.
