What was the biggest turtle ever found?

Archelon is an extinct marine turtle from the Late Cretaceous, and is the largest turtle ever to have been documented, with the biggest specimen measuring 460 cm (15 ft) from head to tail, 400 cm (13 ft) from flipper to flipper, and 2,200 kg (4,900 lb) in weight.

What is the largest leatherback turtle ever found?

The largest leatherback ever recorded was almost 10 feet (305 cm) from the tip of its beak to the tip of its tail and weighed in at 2,019 pounds (916 kg). Weight: 660 to 1,100 pounds (300 – 500 kg).

Are Archelons still alive?

Archelon is an extinct sea turtle which lived approximately 75 million to 65 million years ago during the Late Cretaceous Period. ... This giant turtle could live to 100 years old, possibly thanks to taking long sleeps on the seabed.

Is archelon real?

Archelon, extinct giant sea turtle known from fossilized remains found in North American rocks of the Late Cretaceous epoch (100 million to 66 million years ago). Archelon, protected by a shell similar to that found in modern sea turtles, reached a length of about 3.5 m (12 feet).

Is turtle a dinosaur?

Recent studies have shown that turtles belong in the group Archelosauria, along with relatives like birds, crocodiles, and – you guessed it – dinosaurs. Turtles evolved alongside dinosaurs, with sea turtles emerging as a distinct type about 110 million years ago.

Do leatherback turtles bite?

Can turtles live up to 500 years?

Paleontologists think feathers may have first evolved to keep dinosaurs warm. But while a young T. rex probably had a thin coat of downy feathers, an adult T. rex would not have needed feathers to stay warm.
