Behavior/New Adaptations: Unlike its many offspring, this animal did not have a shell.

Geographical Differences: The animal resided in swamps in Southern Africa.]]> 2023-05-04 12:14:31 UTC https://padlet.com/emunozc16/c2nhecv5kdhxatpd/wish/2578181986 Odontochelys Semitestacea - 232 - 222 Million Years Ago emunozc16 https://padlet.com/emunozc16/c2nhecv5kdhxatpd/wish/2578182067 Structural Changes: The animal had paired bony plates in the plastron and had metaplastic ossification, unlike its ancestors, which had simple rods and no ossification.

Behavior/New Adaptations: The animal started to form the basis of what would be the shell, which would protect the animal from predators

Geographical Differences: The animal lived entirely in coastal and freshwater regions, unlike its ancestor who survived on land and water]]> 2023-05-04 12:14:36 UTC https://padlet.com/emunozc16/c2nhecv5kdhxatpd/wish/2578182067 Protostega - 101 - 66 Million Years Ago emunozc16 https://padlet.com/emunozc16/c2nhecv5kdhxatpd/wish/2578182120 Structural Changes: This animal had a reduction of ossification in its shell that allowed it to manage its weight and flow in water.

Behavior/New Adaptations: This animal had flipper-like front legs that allowed it to traverse the water faster.

Geographical Differences: This animal lived in the Western Interior Seaway, a sea that ran through North America, while the Santanachelys lived in freshwater.]]> 2023-05-04 12:14:39 UTC https://padlet.com/emunozc16/c2nhecv5kdhxatpd/wish/2578182120 Proganochelys - 228 - 201 Million Years Ago emunozc16 https://padlet.com/emunozc16/c2nhecv5kdhxatpd/wish/2578182179 Structural Changes: This animal would also develop paired bony plates instead of paired gastralia like its ancestors, this animal would also have metaplastic ossification and teeth.

Behavior/New Adaptations: This animal would form the upper part of its shell, protecting the animal from predators.

Geographical Differences: This animal lived in small freshwater ponds in Europe, while the Odontochelys lived in both costal and freshwater regions.]]> 2023-05-04 12:14:43 UTC https://padlet.com/emunozc16/c2nhecv5kdhxatpd/wish/2578182179 Kayentachelys - 199 - 183 Million Years Ago emunozc16 https://padlet.com/emunozc16/c2nhecv5kdhxatpd/wish/2578182236 Structural Changes: This animal formed an epiplastron unlike its past ancestors

Behavior/New Adaptations: The size of this animal's fenestra ovalis differs from the Proganochelys and its other ancestors

Geographical Differences: This animal lived in wetlands located in the Navajo region of Arizona, while the Proganochelys lived in freshwater ponds]]> 2023-05-04 12:14:46 UTC https://padlet.com/emunozc16/c2nhecv5kdhxatpd/wish/2578182236 Archelon - 84 - 66 Million Years Ago emunozc16 https://padlet.com/emunozc16/c2nhecv5kdhxatpd/wish/2578182276 Structural Changes: This animal, similar to its ancestor, gained strong front feet that helped this animal navigate through strong waters.

Behavior/New Adaptations: This animal gained a hooked beak with a powerful jaw for resources.

Geographical Differences: This animal also lived in the Western Interior Seaway.]]> 2023-05-04 12:14:49 UTC https://padlet.com/emunozc16/c2nhecv5kdhxatpd/wish/2578182276 Santanachelys Gaffneyi - 120 Million Years Ago emunozc16 https://padlet.com/emunozc16/c2nhecv5kdhxatpd/wish/2578182356 Structural Changes: This animal had distinguishable tips on its forearms and had large salt glands.

Behavior/New Adaptations: This animal is fully adapted to marine environments and has fully formed proper protection from sealife predators.

Geographical Differences: This animal lived in freshwater bodies of water in Eastern Brazil, while the Kayentachelys lived in wetlands in the Navajo Region.]]> 2023-05-04 12:14:54 UTC https://padlet.com/emunozc16/c2nhecv5kdhxatpd/wish/2578182356 Stupendemys - 13 - 5 Million Years Ago emunozc16 https://padlet.com/emunozc16/c2nhecv5kdhxatpd/wish/2578182410 Structural Changes: This animal was massive compared to its ancestors and the species of sea turtles that came after this animal.

Behavior/New Adaptations: This animal had a huge skull and horns of the carapace of males for resources.

Geographical Differences: This animal lived in parts of South America in freshwater wetlands, while the Archelon lived in the Western Interior Seaway]]> 2023-05-04 12:14:57 UTC https://padlet.com/emunozc16/c2nhecv5kdhxatpd/wish/2578182410 Colossochelys - 2.5 Million Years Ago emunozc16 https://padlet.com/emunozc16/c2nhecv5kdhxatpd/wish/2578182460 Structural Changes: This animal is known as the largest land tortoise in history.

Behavior/New Adaptations: Its size allowed it to camouflage easily from predators.

Geographical Differences: This animal lived on the shores of Central Asia, India, and Indochina, while the Stupendemys lived in wetlands in South America.]]> 2023-05-04 12:15:00 UTC https://padlet.com/emunozc16/c2nhecv5kdhxatpd/wish/2578182460 Galapagos Tortoise - Today emunozc16 https://padlet.com/emunozc16/c2nhecv5kdhxatpd/wish/2578182579 Structural Changes: This animal has two variations, each with different shells.

Behavior/New Adaptations: The new shell allows this animal to reach different forms of food depending on its environment

Geographical Differences: This animal lives in dry lowlands on the Galapagos Island, while the Colossochelys lived on the shores of Eastern countries]]> 2023-05-04 12:15:05 UTC https://padlet.com/emunozc16/c2nhecv5kdhxatpd/wish/2578182579 Sources emunozc16 https://padlet.com/emunozc16/c2nhecv5kdhxatpd/wish/2578183591 https://prezi.com/p/oa5ltsgrods0/turtle-evolution-timeline/
