Parocnus is an extinct genus of sloth native to Cuba and Hispaniola, belonging to the family Megalocnidae. It was a terrestrial ground sloth, being the second largest Caribbean sloth after Megalocnus,[1] with the body mass of the various species of the genus estimated at around 32–79 kilograms (71–174 lb),[2] comparable to a pig.[3]
