All reptiles share several key characteristics including having dry and scaly skin, being cold-blooded, laying shelled eggs, and having a backbone. Additionally, most reptiles have four legs with clawed toes or no legs at all.
they are warm blooded, they have tails, and they sometimes eat plants.
The dinosaurs that walked on four legs had hips like some lizards. Also dinosaurs had scales and claws.
One characteristic all reptiles share is that they are all cold-blooded.

Were all dinosaurs reptiles?
No way! There were thousands of species of reptiles that lived both during, before, and after the dinosaurs lived on earth. There were the synapsid reptiles, as well as the anapsid reptiles, which were mostly gone when the dinosaurs arrived. There were also many diapsid reptiles that lived during the time the dinosaurs did. Such species include deinosuchus, dimetrodon, gorgonops, Quetzalcoatlus, and rutiodon. Dinosaurs were not reptiles themelves. They evolved from reptiles, many had warm blood even feathers,
Do all mammals have a common ancestor?
Yes, all mammals share a common evolutionary ancestor. Mammals belong to the same taxonomic class, Mammalia, which indicates their common evolutionary heritage. This common ancestor likely existed around 200-230 million years ago.
Is DNA of a lizard more similar to a dog or snake?
The DNA of a lizard is more similar to a snake than a dog, as they are both reptiles. Reptiles share genetic similarities due to their evolutionary history and shared characteristics.
Is DNA a characteristic for all living things share?
Yes, DNA is a characteristic that all living things share. To be more precise, all living things share a form of genetic material, which is DNA.
How comparative morphology support theory of evolution?
Look to the morphologies of all mammals and see rather easily how closely related they are in comparison to the more distantly related morphologies of all reptiles. Ancestral traits, such as tetropodal arrangement of limbs and then derived differences between mammals and reptiles. Reptiles having scales and mammals having hair.
What do all reptiles share?
One characteristic all reptiles share is that they are all cold-blooded.
Are all dinosaurs reptiles?
All reptiles are diapsids. Mammals (like you and I) are, in contrast, synapsids. So in that respect all reptiles are alike. However, I would not say they were all alike. Snakes are reptiles but lack limbs. Alligators are also reptiles, as are lizards. Tuatara, gavials, amphisbaenids, and tortoises each represent one of the four main modern orders of reptiles. They share some characteristics--just as you and I do, but I would not say they were all alike.
What does A Fish and amphibians and reptiles and mammals and and Birds All Share?
A heart! respiratory systems, all are heteratrophic organisms, all use sexual reproduction (with a few exceptions here and there.)
Does all reptiles have ribs or not?
no all reptiles does not have ribs
Do Marsupials share characteristics with other animals from other groups?
Marsupials are mammals, so share all features with other mammals. As well, they are vertebrates, so share the characteristic of having a backbone with birds, fish, reptiles and amphibians. Like birds and reptiles, mammals breathe via lungs (rather than gills), and like birds, they are warm-blooded.
Reptiles and amphibians share a number of features except what?
Mode of reproduction
Which reptiles are vertebrates?
Yes, mammals, birds and reptiles are all vertebrates.
All reptiles have scales?
Yes, all Reptiles do have scales.
Is the hawksbill turtle a mammal?
No, they are reptiles. ALL turtles are reptiles.
Do birds and reptiles share a common ancestor?
Yes. If you go back far enough, all life on Earth shares a common ancestor.
Are all raptiles the same?
All reptiles have some of the same characteristics, but all are different in their own ways. The characteristics they share is that they are cold blooded. This means that they do not have an internal heating system that raises their body temp, so they must sit in a warm spot to get warm. They also have scales, not skin. All reptiles lay eggs.
ARe all snakes reptiles?
Yes all rattle snakes are reptiles.
