An international team of researchers has discovered two new species of prehistoric cockroaches dating back to the dinosaur era. The cave-dwelling roaches were found preserved in amber in the Hukawng Valley in Myanmar. The newly discovered species named Crenocticola svadba and Mulleriblattina bowangi dated around 99-million-years ago, putting them in the Cretaceous period. These are the oldest examples of organisms that adapted to a life flourishing in the darkness of caves. These creatures are recognized by their tiny eyes, small wings, pale bodies, long legs, and antennae. The researchers believe more research is needed to determine if the discovered two new species survived the mass destruction that wiped out the dinosaurs.
