A world analysis staff led by Dr. Gabriel S. Ferreira from the Senckenberg Middle for Human Evolution and Paleoenvironment on the College of Tübingen has described a brand new species of big turtle from the late Pleistocene.
Peltocephalus maturin is between 40,000 and 9,000 years outdated and comes from the Brazilian Amazon. With a shell size of about 180 centimeters, the species is likely one of the largest recognized freshwater turtles on the planet. The armored reptile was named after the enormous turtle “Maturin,” a fictional character created by best-selling creator Stephen King.
With a most shell size of 140 centimeters, the Asian narrow-headed softshell turtle (Chitra chitra) along with the roughly 110-centimeter-long South American river turtle (Podocnemis expansa) is likely one of the largest freshwater turtles alive right now.
“Up to now, we solely know of some turtles residing in recent waters that had a shell size of greater than 150 centimeters,” explains Dr. Ferreira. “Such massive animals are most lately recognized primarily from the Miocene, the interval round 23 to five million years in the past.”
Ferreira and a world staff have now found a large consultant of this order of reptiles from the top of the Pleistocene interval, round 40,000 to 9,000 years in the past, and described it as a brand new species. The fossil stays—a part of the turtle’s decrease jaw—have been collected by gold miners on the “Taquaras” quarry in Porto Velho, Brazil.
Primarily based on varied traits, the analysis staff assumes a detailed relationship with the fashionable big-headed Amazon turtle (Peltocephalus dumerilianus) and an omnivorous weight loss plan. “We named the brand new species after the enormous turtle Maturin, an overarching protagonist within the Stephen King multiverse. Maturin is accountable for the creation of the universe in King’s novels and movies,” explains Dr. Ferreira.
The paper is printed within the journal Biology Letters.

Referencing the turtle’s extraordinarily massive measurement, Dr. Ferreira says, “That is very shocking as a result of freshwater turtles—in distinction to their terrestrial and marine kinfolk—not often have such gigantic varieties and the youngest big fossils recognized up to now come from Miocene deposits.”
The brand new discover is the youngest recognized prevalence of big freshwater turtles and suggests a coexistence of Peltocephalus maturin with early human inhabitants within the Amazon area.
“Individuals settled within the Amazon area round 12,600 years in the past. We additionally know that giant tortoises have been on the weight loss plan of hominins because the Paleolithic. Whether or not freshwater turtles, that are rather more tough to catch because of their agility, have been additionally eaten by early people and whether or not Peltocephalus maturin—along with the South American megafauna—fell sufferer to human growth remains to be unclear.
“Right here we’d like extra information from the Late Pleistocene and Early Holocene deposits of the Amazon Basin,” says Ferreira, giving an outlook on future work.
