Arapim

Arapim is a genus of extinct prehistoric monitor lizards that lived during the Cretaceous period. The name "Arapim" is derived from the Greek word "ara" meaning "altar" and the suffix "-apim" which is a common combination in many fossil genus names. This name was chosen due to the discovery of the first Arapim fossils near an altar in Brazil.

Arapim is often referred to as the largest prehistoric lizard to have existed, with estimates suggesting that individual specimens could reach lengths of up to 17 meters and weigh several tons. However, more recent studies have cast doubt on these claims, suggesting that Arapim may not have been as massive as originally thought.

The Arapim genus consists of two known species: Arapim morochii and Arapim robustus. Arapim fossils have been found in Brazil and Argentina, which suggests that this genus was present in South America during the Cretaceous period.

Some scientists have questioned the accuracy of the Arapim fossil records, suggesting that they may have been misidentified or even hoaxed. However, most paleontologists still consider Arapim to be a valid and important discovery that provides insights into the evolution of monitor lizards.

Despite its unclear status, Arapim remains a significant discovery in the field of paleontology and continues to be the subject of ongoing research and debate. As more evidence comes to light, it is likely that our understanding of Arapim will be refined, and its place in the history of monitor lizards will be clarified.
