What are therapods?

Where there survivors from the dinosaur times?

Yup. All the birds you see today are dinosaurs, therapods.

Which of the three taxa of dinosaurs which do birds belong?

Dinosaurs were divided into two big groups: ornistichia (bird hip) and saurischia (lizard hip). The confussing part is that scientists believe that birds evolved from a group of therapods similar to small velociraptors and therapods are saurischia.

What features are found in therapods?

Theropods are a type of dinosaur. This type of dinosaur is characterized by short arms, big jaws, and walking upright.

What are five types of dinosaurs?

Five types of dinosaurs are sauropods, carnosaurs, therapods, ceratopsians and hadrosaurs

What did pterodactyl eat?

oh just therapods!Pterodactylus was carnivorous and had a wing span of about 5 feet. Thus, they would have likely eaten small animals, like lizards and primitive mammals, as well as fish and insects.

What is the first dinosaur?

The first Dinosaurs were small Therapods (fast carnivorous/meat- eating Dinosaurs). Until recently the oldest Dinosaur known was the Eoraptor. Unlike many other Therapods it had five digits (fingers). Through time Therapods gradually lost digits. But there was one thing about its hand- two of the fingers were stubby while the three others were perfect for grasping. Herresaurus was the second oldest Dinosaur known until recently. It also had five digits and two stubby ones. This hunter was no small Dinosaur- it was 10 ft long! Scientists think it ate Mammals and small Theraspids. Eoraptor probaly only ate Mammals and Insects. Eoraptor and Herrerasaurus are part of the earliest group of Dinosaurs- Herrerasaurs. It was not long until a new group of Therapods appeared. These were the Ceratosaurs. They had S- shaped necks and hollow bones. One of the first Ceratosaurs was Coelophysis. It was a small and agile hunter. It was named for its hollow bones and once a Coelophysis fossil was found in space! Now lets move on to the herbivores (plant- eaters). The herbivorous Dinosaurs evolved from Therapods. The earliest herbivorous Dinosaurs were the Prosaurapods which later gave rise to the Saurapods (huge long- necked Dinosaurs). The Prosaurapods were armed with a pair of thumb claws. It is possible that some Prosaurapods were omnivores (animals that eat both plants and meat) and used these thumb claws to take down their prey. Some Prosaurapods also had fangs like the Therapods (Prosaurapods were more closely related to the Therapods then other herbivorous Dinosaurs). One of these Prosaurapods was Riojasaurus. Riojasaurus was one of the largest Prosaurapods (it grew up to 30- 36 ft long). It also belonged to the group of the largest Prosaurapods to ever walk the Earth- the Melanorosaurids. Not all Prosaurapods were huge. Some were small like Anchisaurus which was only 3 meters tall on its hind legs. And some were medium sized like Plateosaurus. Plateosaurus was 27.5 meters long. Now we can move on to the smaller herbivorous Dinosaurs- Ornithschians. The Ornithschian group was divided into 3 groups- Marginocephalians (the horned and bone- headed Dinosaurs), Thyreophorans (the armoured and spiked/plated Dinosaurs), and finally, the Ornithopods. The Ornithopods were the first Ornithschians. They came in all shapes and sizes- some were small, some were huge, some were known as the Dinosaur gazelles, some were slow, and some were even partly covered in protofeathers (a feather- like substance that warmed up the bodies of Dinosaurs). Pisanosaurus was one of the first Dinosaurs. Only partial fossils of this small Dinosaur have been found in Argentina. Then we have Lesothosaurus which will be the only other Ornithopod I'll tell about in this answer. Lesothosaurus was first found in Lesotho, Africa. This small Dinosaur was only 3 ft long like Pisanosaurus and was a fast runner. These are some facts about the first Dinosaurs. Hope this helps!

Is a direct living descendant of dinosaurs a parrot or an alligator or a dragonfly or a hippo?

The Parrot would be the direct ancestor of the Dinosaur. The therapod line is believed to be the line that turned into our modern day birds. There are many similarities between therapods and our modern birds. There is some debate on this theory still but there are many who believe that the birds are direct descendants of the dinosaurs

Did dinosaurus lay egg like spinosaurus?

Most of the major dinosaur groups are known to have been oviparous similar to modern birds and therefore would have laid eggs. The Therapods as a group laid eggs and brooded over their nests. Spinosaurus being a Therapod was probably no different. However, the discovered remains of Spinosaurus is scarce, and no eggs have been found confirmed to be from this species.

What animal group includes the closest relatives to the birds in terms of evolutionary relationship?

A raptor was closely related to a bird because when the raptors or two legged herbivores were running away from predators then as they ran away they had to run up steeper things too get away and that is how they developed wings to help then get up steeper things.

In what ways is a bird different from other vertebrates?

Birds are unique in having feathers; no other modern vertibrate have them, birds are also unique in having a furcula - a wish bone. The therapod dinosaurs had both feathers and wish bones, and it is believed that modern birds evolved from therapods.

Why did dinosaurs like tyrannosaurs walk on two legs?

Animals walk on four legs because it is more stable than walking on two legs. Dinosaurs were very large, and it would have taken a lot of energy for them to walk on two legs. The ones who did walk on two legs were usually predators (like Tyrannosaurus rex or velociraptor) because they could get more energy from eating other animals than from eating plants.

Was a spinosaurus fast?

I dont think there was an estimated speed but i think its been said that it could run fast
