A world analysis workforce led by Dr. Gabriel S. Ferreira from the Senckenberg Middle for Human Evolution and Paleoenvironment on the College of TĆ¼bingen has described a brand new species of big turtle from the late Pleistocene.
Peltocephalus maturin is between 40,000 and 9,000 years previous 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 this 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 at this time.
“Prior to now, we solely know of some turtles dwelling in contemporary waters that had a shell size of greater than 150 centimeters,” explains Dr. Ferreira. “Such giant animals are most lately recognized primarily from the Miocene, the interval round 23 to five million years in the past.”
Ferreira and a global workforce have now found an enormous consultant of this order of reptiles from the tip of the Pleistocene interval, round 40,000 to 9,000 years in the past, and described it as a brand new species. The fossil staysāa part of the turtle’s decrease jawāhave been collected by gold miners on the “Taquaras” quarry in Porto Velho, Brazil.
Primarily based on varied traits, the analysis workforce assumes a detailed relationship with the fashionable big-headed Amazon turtle (Peltocephalus dumerilianus) and an omnivorous weight loss program. “We named the brand new species after the enormous turtle Maturin, an overarching protagonist within the Stephen King multiverse. Maturin is chargeable for the creation of the universe in King’s novels and movies,” explains Dr. Ferreira.
The paper is revealed within the journal Biology Letters.

Referencing the turtle’s extraordinarily giant measurement, Dr. Ferreira says, “That is very stunning as a result of freshwater turtlesāin distinction to their terrestrial and marine relationsānot 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 incidence 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 program of hominins because the Paleolithic. Whether or not freshwater turtles, that are far more troublesome to catch as a result of their agility, have been additionally eaten by early people and whether or not Peltocephalus maturināalong with the South American megafaunaāfell sufferer to human growth continues to be unclear.
“Right here we’d like extra knowledge from the Late Pleistocene and Early Holocene deposits of the Amazon Basin,” says Ferreira, giving an outlook on future work.
