When did dinosaurs live?

Dinosaurs lived in the Mesozoic Era which took place between 245 and 66 million years ago. The Mesozoic Era is divided into 3 time periods: Triassic (252 to 201 million years ago), Jurassic (201 to 145 million years ago), and Cretaceous (145 to 66 million years ago).

Why were dinosaurs so big?

Paleontologist believe dinosaurs grew so big in order to gain protection from predators, help regulate internal body temperature, and to allow them to reach their source of food. Today, whales are the only animal who are close to the size of dinosaurs.

Where did dinosaurs live?

Dinosaur fossils have been found on every continent, proving that they lived in every environment of the world. During the Triassic period the continents were one supercontinent called Pangea. The continents slowly spread across the world into the arrangement that they are at today.

What causes animals to go extinct?

The factors that cause animals to go extinct are mainly the loss and degradation of habitat which is mainly due to deforestation. Other causes for animals going extinct are exploitation through hunting and overfishing, invasive species, and climate change. Plastic pollution and emerging diseases are also factors that play a role in the extinction of animals.

Can extinct animals be brought back?

Extinct animals have not successfully been brought back as of today. Scientists need to sequence its genome and then edit the DNA of a close living relative to match it. Afterwards, they would need to make embryos with the revised genome and have a surrogate mother carry them.

Which animals have gone extinct because of climate change?

Animals that have gone extinct because of climate change include the golden toad and the north Atlantic cod is threatened. The staghorn coral and orange-spotted filefish have also had their population numbers affected by the effects of climate change. It is up to humans to make the necessary changes and help endangered animal species.

What do reptiles eat?

Reptiles are typically carnivores and feed on eating other animals like insects, mollusks, birds, frogs, mammals, fishes, or sometimes other reptiles. Some reptile species like land tortoises are vegetarians and eat leaves, grass, or cactus while the marine iguana dives into the sea to obtain seaweed for consumption.

Why do reptiles shed?

Reptiles shed their skin so that they can continue to grow. When they shed, reptiles grow a new layer of skin underneath their old skin and then shed their old one. When they shed their skin reptiles also get rid of any parasites during the process. The process of shedding is referred to as sloughing.

When did reptiles first appear?

Reptiles first appeared 315 million years ago during the time period known as the Late Carboniferous Period. This time period is also referred to as the Pennsylvanian and the Coal Age. The first reptile is considered to be the Hylonomus lyelli and is also the first animal known to have fully adapted to life on land.

What are common characteristics of the animals that live in swamps?

The most common characteristics of the animals that live in swamps include having webbed feet to help them move quickly through water environments as well as camouflage to protect themselves. Camouflage also helps them hide within their surroundings and hunt. Animals that live in swamps also can remain in the water for an extended time.

What do swamp animals eat?

Swamp animals typically eat insects, spiders, earthworms, as well as slugs. Swamp animals usually eat the animals that fall below them in the food chain and are native to the swamp habitats. Swamp Animals often eat small fish, insects, crustaceans, and mollusks. Herbivore swamp animals eat algae, water lilies, cattails, and algae.

How do wetlands help endangered species?

Wetlands help endangered species because they improve water quality and provide wildlife habitat. Wetlands are also important as they maintain ecosystem productivity, reduce coastal storm damage, and provide recreational opportunities. Wetlands are significant in the preservation of endangered species by improving water supply and providing possibilities for education.

How do grazing animals help grasslands?

Grazing animals help grasslands by maintaining the ecosystem as well as stimulating plants for new growth. The constant grazing of these animals helps trigger biological activity while promoting nutrient exchanges. Grazing animals also help compact soil with their hooves as well as open new areas for seeds to spread.

What are grazing animals called?

Grazing animals are called ruminants as they eat by looking for forage, selecting the grass, and then grabbing and eating the forage with their mouth. Ruminants stand out from other animals as the way that they grasp and ingest food is different. Grazing animals also move differently in new pastures than other animals.
