Dinosaurs were a diverse group of reptiles that lived during the Mesozoic Era, which spanned over 180 million years and ended 66 million years ago. While the majority of the species went extinct at the end of the Cretaceous period, some dinosaurs evolved into the animals we know today. Here is a list of ten animals that evolved from dinosaurs.
10- Ostrich
Ostriches are the largest living bird species, and they evolved from dinosaurs. They are the last survivors of the Struthioniformes, a group of flightless birds that once roamed the earth millions of years ago. Their ancestors first appeared in the fossil record during the Late Cretaceous period, approximately 66 million years ago. During this time, their ancestors were small, flightless creatures that lived in the forests and plains of North America and Asia.
Over time, they evolved into larger, flightless birds. During the Miocene epoch, around 20 million years ago, ostrich-like birds began to spread across Africa and Europe. These birds had long legs and were well adapted to running and foraging for food.
9- Monitor Lizard
Monitor lizards evolved from dinosaurs. They are believed to have diverged from the dinosaurs around 60 million years ago. The earliest known monitor lizard fossils date back to the mid-Miocene period, around 15 million years ago. These reptiles have since evolved to become one of the most successful groups of lizards in the world.
Monitor lizards typically have long necks, powerful tails, and well-developed limbs. Their scales are usually smooth and shiny and they have long tongues that they use to sense vibrations and smell. These lizards are also highly adapted to their environment and can be found in a wide range of habitats, from deserts to rainforests.
8- Turtles

Turtles evolved from dinosaurs. This is a fact that has been studied and discussed for many years. The exact process of how this evolution occurred is still unknown. Scientists believe that turtles evolved from a group of ancient reptiles known as thecodonts. These small, primitive animals were closely related to the dinosaurs.
Thecodonts had a hard carapace, or outer shell, that provided protection from predators. Over time, this shell developed into the shell of the modern-day turtle. Scientists believe that this carapace evolved as a way to protect thecodonts from predators. Thecodonts also had four legs and a long tail. Over time, the hind legs of thecodonts became flatter and longer, forming the flippers that are seen in modern-day turtles. The long tail also became shorter and more flexible, allowing turtles to maneuver in the water.
7- Emu

The story of the emu is an interesting one, as it is a species that has evolved from its dinosaur ancestors. It is believed that the emu, like other modern birds, is descended from theropod dinosaurs. This incredible creature has adapted and evolved over millions of years, resulting in the modern-day emu.
The emu belongs to the ratite family, a group of flightless birds that also includes the ostrich, rhea and kiwi. As such, it is thought that the emu is closely related to the ancient dinosaurs that inhabited the planet millions of years ago.
6- Snakes

Snakes evolved from dinosaurs. This remarkable transition took place over millions of years. During this period, snakes developed unique adaptations that enabled them to survive and thrive in a variety of different environments. One of the most obvious changes was the loss of limbs, which allowed snakes to move quickly and silently across the ground and into crevices. This adaptation was also accompanied by an increase in the number of vertebrae, which gave the snake increased flexibility and maneuverability. The scales and overlapping plates of a snake’s skin also evolved to protect the snake from predators and the elements.
Snakes also developed an enhanced sense of smell, which allowed them to detect prey and predators from a distance. In addition, the development of a venomous bite enabled them to effectively defend themselves and hunt prey. This combination of features made snakes an incredibly successful group of animals.
5- Cassowaries

Cassowaries evolved from dinosaurs hundreds of millions of years ago. Their family tree is closely linked to the lineage of other large flightless birds, such as ostriches and emus. These prehistoric creatures have been around for a long time, and today, they continue to inhabit the forests and grasslands of Australia and New Guinea.
The cassowary is a large, flightless bird with distinctive features. It has a small head, large body, and strong, long legs. Its neck is short and its feathers are stiff, giving it a unique, spiky look. Its feet have three toes, each equipped with a long, sharp claw.
The cassowary has an impressive range of adaptations that allow it to survive in its environment. It is incredibly fast, and its powerful legs and long toes help it to move quickly through dense vegetation. The long claws on its feet are used for defense and to help it move efficiently through the underbrush.
4- Crocodiles
The transition from dinosaur to crocodile marked a major shift in the evolution of the species. As dinosaurs evolved to become more efficient predators, they began to develop features that were more suitable for aquatic life. These features included webbed feet, a long, powerful tail and a thick, scaly hide. Over time, the dinosaurs’ physical features gradually changed, eventually giving rise to the modern-day crocodile. Crocodiles have a muscular body with a long, flat snout that is perfect for catching prey. Their webbed feet give them extra speed and agility in the water. They have powerful jaws and sharp teeth that are used to tear apart their food. Their thick, scaly skin is made up of tough overlapping plates, providing them with protection from predators.
Crocodiles also have a unique ability to regulate their body temperature. They can bask in the sun to warm up, or they can submerge themselves in the water to cool down. This allows them to survive in a range of environments, from tropical swamps to cooler desert regions. Unlike most reptiles, crocodiles are social animals. They live in groups called pods and are known to help each other out with hunting, egg guarding, and defending their territory. This behavior is a key factor in their success as a species.
3- Tuatara
Tuatara are reptiles, closely related to lizards, snakes, and crocodiles, that have been around since before the dinosaurs. They are the only surviving members of the Sphenodontia family, which has been around since the Triassic period, around 250 million years ago.
Tuatara have a number of unique characteristics that set them apart from other reptiles. They have a two-pronged lower jaw and a third eye, which is found on the top of their head and helps them regulate their body temperature. They also possess a full set of teeth in the lower jaw, which is highly unusual for reptiles. Although tuatara may appear sluggish and slow, they are capable of short bursts of speed and can even swim. They are also very long-lived, with some recorded tuatara living for over 100 years!
2- Shoebill

Shoebill storks evolved from dinosaurs and are now a unique species of their own. These large birds, which can grow up to five feet tall, have long legs, wide wings and a distinctive bill that resembles a shoe. They are found in isolated swamps and wetlands in tropical regions of central and east Africa.
Shoebill storks are believed to have descended from the group of dinosaurs known as the ornithopods. These two-legged herbivorous dinosaurs included the iguanadon, the hadrosaur, and the hypsilophodon. While these dinosaurs are now extinct, the Shoebill stork has adapted to its environment and continues to thrive in the African wetlands.
1- Chicken
The evolution of chicken from dinosaurs is a fascinating journey. Dinosaurs first appeared during the Triassic period, about 230 million years ago. Over time, they diversified into a wide variety of species, some of which eventually evolved into birds. It was during the Cretaceous period, about 65 million years ago, that the last common ancestor of modern birds and dinosaurs lived. This ancestor is thought to have resembled a small, feathered, two-legged theropod.
As theropods evolved, some of them developed features that allowed them to take to the air. They grew feathers, which provided insulation and allowed them to fly. They also began to develop a keel on their breastbone, which provided an anchor for their flight muscles. This adaptation allowed them to become more agile in the air, and eventually became the ancestor of modern birds.
From this ancestor, chickens began to emerge. It is thought that modern chickens descended from the red junglefowl, which is native to South Asia. Through selective breeding, chickens began to take on the characteristics we recognize in them today. For example, humans bred chickens for bigger breasts, and others for more productive egg laying.
