Charles Lamberton (1876–1960) was a French paleontologist who lived and studied on the island of Madagascar between 1911 and 1948 and specialized in the recently extinct subfossil lemurs. He made significant contributions towards fixing misattributions of skeletal remains and poor interpretations of subfossil lemur behavior. His paleontological expeditions during the 1930s led to the discovery of a new species of Mesopropithecus, a type of sloth lemur. Three species—one mammal and two reptiles—were named after him, although one is now considered a taxonomic synonym.
Charles Lamberton lived on the island of Madagascar between 1911 and 1948, where he was employed as a Professor at Gallieni College and as a Secretary for the Malagasy Academy. During much of his career, which spanned from 1912 to 1956, he wrote extensively about the recently extinct, subfossil fauna of Madagascar.
For nearly 50 years, Lamberton studied the subfossil lemurs, a group of extinct, giant lemurs that died out shortly after the arrival of humans to the island. During the 1930s, Lamberton led several paleontological expeditions primarily to the southwest of Madagascar. In 1936, based on cranial remains he had discovered, Lamberton named and described a species of sloth lemur, Mesopropithecus globiceps, which he initially placed under another genus.
During the early 1900s, reconstructions of subfossil lemurs were poor interpretation due to misattributions of postcranial bones. Although other paleontologists had begun correcting misattributed bones and issues of synonymy, Lamberton fixed more misattributions and poor interpretations of subfossil lemur remains than any other paleontologist. In 1947, he correctly identified the postcranial remains of the sloth lemur, Palaeopropithecus, which Guillaume Grandidier had mistakenly attributed to a giant tree sloth he called Bradytherium. Ten years later, in 1957, he wrote a crushing rebuttal to Italian paleontologist Giuseppe Sera by pointing out many skeletal misattributions and tactfully refuting his misinterpretation of the koala lemur (Megaladapis) as a ray-like swimmer and his fancifully creative "arboreal-aquatic acrobat" theory for Palaeopropithecus. Both Lamberton and British paleontologist Alice Carleton showed that Palaeopropithecus was suspensory; however, Carleton proposed that Palaeopropithecus was sloth-like, while Lamberton predicted locomotion more similar to that of an orangutan. It wasn't until the late 1900s that subfossil discoveries demonstrated that Palaeopropithecus was more sloth-like.
