Are snakes related to dinosaurs

Answer 1

Dinosaurs evolved from their earlier archosaur ancestors in the Triassic Period. The fundamental difference between dinosaurs and other reptiles is the structure of their hips. In most reptiles the legs are splayed out, limiting their locomotion. In dinosaurs they are erect and located on the underside of the body, allowing dinosaurs to have more stamina.

Dinosaurs diverged from their archosaur ancestors approximately 230 million years ago in the Middle to Late Triassic Period. It is believed that Eoraptor ("dawn thief") represents the common ancestor of all dinosaurs. If this is so, the first dinosaurs were small, bipedal predators. As earlier forms of reptiles became extinct the dinosaurs grew and diversified, and became the dominant terrestrial animals throughout most of the Mesozoic Era. They occupied various niches. Some were small insectivores, some were vicious predators, and others were the giant sauropods.

Answer 2

it is theorized that birds evolved from the smaller theropods
there is a mountain of evidence suggesting this because
of skeletal similarities and feathers in most theropods
and birds

Answer 3

No is not thought that snakes evolved from dinosaurs. They evolved from a completely different branch of the reptile family.

Snakes, lizards, crocodiles, dinosaurs (birds) etc have common ancestors in the sauria clade of reptiles.

The sauria evolved into several different groups :-

• Ichthyosaursia which become would ichthyosaurs
• Saurpterygia which would become pliesosaurs
• Lepidosauromorpha which would become lizards, mosasaurs & snakes
• Archosauromorpha which would become pterosaurs, dinosaurs, birds & crocodiles.

Answer 4

The origin of snakes is kind of mysterious, since they have all these little bones and don't make good fossils. This is what some scientists THINK happened:

Dinosaurs were reptiles (although some were a good deal like birds), but there were also reptiles which weren't dinosaurs. [Ignore the fact that "dinosaur" means "terrible lizard"; that was a mistake; we should really call them something else.] These were the turtles, who ARE older than the dinosaurs, and the lizards. With dinosaurs dominating the Earth, the way for lizards to survive was to stay out of the way. One kind of lizard found that creeping into small crevices was a good way to do this. Well, when one is trying to fit into small places, legs are more in the way than useful and external ears just tend to collect dirt. Over time, these lizards changed into snakes, which still have scales and scutes and flickering tongues, but no legs and no ears.

Answer 5

Only distantly, though both are technically reptiles. Dinosaurs are actually more closely related to birds than they are to snakes. The last common ancestor of snakes and dinosaurs lived in the Permian period, more than 250 million years ago.

Answer 6

Snakes didn't evolve from dinosaurs. They evolved from lizards. It is debated among scientists as to whether they evolved from a burrowing or a swimming ancestor.

Answer 7

snakes directly evolved from the garden lizard.
