"Last year scientists described the body of a squirrel-like rodent found for sale in a meat market in Laos. They believed it belonged to a previously undescribed family and named it Laonastes aenigmamus."

"But they failed to fully inspect the fossil record. Upon closer analysis of the creature's teeth, a second group of researchers determined it was a member of the previously known rodent family Diatomyidae. "

"Diatomyidae were squirrel-sized rodents that lived during the middle Tertiary period 34 million to 11 million years ago in southern Asia, central China, and Japan. They also had highly characteristic molar teeth and jaw structure, which is how the researchers reclassified Laonastes."
