Be The Change!

Turtles have existed since the late permian epoch, they evolved
many times in different ways! The first appearance of turtles was
a reptile called Eunotosaurus, This reptile is a Stem turtle. Stem
turtles are animals that definitely relate to turtles but are not
them. Then, there was a Eorhynchochelys. This reptile developed
a shell under the stomach. Then, the Proganochelys came in. This
reptile was the first who had a proper shell. Finally, the
Desmatochelys was the first proper sea turtle to exist, it was
huge. The total length of it was 2m. In Qatar, there are 5 species
of sea turtles that can be observed.
Archelons first appeared during the Triassic period, meaning they
came at the same time as Dinosaurs, marine reptiles, lizards,
crocodiles, and more. This was part of some of the early stages of
life on earth. These creatures lived through every life stage on
earth until now, some of these stages were when the dinosaurs
went extinct because of asteroids and volcanoes. So how did
Archelons survive?
Essentially, since their physical processes were so slow and
required so little energy, they could survive on scarce resources
during and after the dinosaur extinction. The conclusion is based
on the discovery of a turtle fossil in North Dakota that goes back
60 million to 65 million years. The specimen belongs to a turtle
species that is assumed to have survived global extinction
because fossils of the same species were discovered in rock layers
deposited up to 75 million years ago.
The global extinction event that wiped out the dinosaurs, known
as the K-T boundary because of its unique signature in rock layers,
was most likely caused by a meteorite strike, though the exact
sequence of events is still being debated. Some researchers
believe the meteor triggered a series of world-shattering volcanic
eruptions, which may or may not have been caused by the meteor.
