Dinosaurs belong to the same order as alligator, though they are not dinosaurs. Their ancestors were related to dinosaurs and walked the earth at the same time. Dinosaurs went extinct, but alligator ancestors went on to evolve into the alligators we see today.

Are alligator and crocodiles dinosaurs?
Alligators (and other crocodilians, such as crocodiles and caimans) are not dinosaurs. Crocodilians are not directly descended from dinosaurs, but they are related to them. Dinosaurs are the closest living relatives of birds, mammals, reptiles, and amphibians. All of these groups share a common ancestor that lived about 65 million years ago.
Dinosaurs and birds were the first groups of animals to evolve from a single ancestor, called the “Cretaceous-Tertiary boundary” (CTB). CTB is the boundary between the Triassic and Jurassic periods of the Earth’s history. It was a time of great environmental change, including the end-Permian mass extinction event, which wiped out the majority of all life on Earth.
Is an alligator The closest thing to a dinosaur?
Crocodilians are the most closely related group. Before crocodiles were put in the larger family group, archosaurs, they evolved. Birds are the only descendants of the giant, extinct dinosaurs, and crocodiles and alligators are related to birds. The crocodile is the largest living reptile. It is found in tropical and subtropical regions of Africa, Asia, Australia, South America and the Caribbean.
What animal is closest to a dinosaur?
Birds are thought to be the only animals around today that are direct descendants of dinosaurs. Next time you visit a farm, take a moment to think about it. The most incredible predator the world has ever known is actually the closest living relative to the squawking chickens.
Do any dinosaurs still exist?
Birds are a living group of dinosaurs because they descended from the same family of dinosaurs. Dinosaurs were not the first animals to walk the Earth, but they are the only ones that have survived to this day. Dinosaurs have been around since the Mesozoic Era, which lasted from 251 million to 66 million years ago.
The dinosaurs that lived during this time period are known as the Cretaceous-Tertiary Period (C.T.P.), which is the name given to the period of time between the end of the Permian Period and the beginning of Jurassic Period. This period was characterized by the extinction of more than 90 percent of life on Earth.
Is a chicken a dinosaur?
So, are chickens dinosaurs? No – the birds are a distinct group of animals, but they did descend from the dinosaurs, and it’s not too much of a twist of facts to call them modern dinosaurs. The similarities between the two types of animal are due to the fact that they are both herbivores.
Well, the chicken is a bird, while the dinosaur is an extinct animal that lived during the Cretaceous period, about 65 million years ago. The chicken, however, is not a true dinosaur, as it is more closely related to modern birds than to the modern-day tyrannosaurs, such as T. rex and Velociraptor.
Is a turtle a dinosaur?
Turtles provide a connection to our huge reptiles from millions of years ago, the dinosaurs. The turtles have a lot in common with dinosaurs, even though they are not as closely related as birds. For example, they both lived in the same time period (the Cretaceous Period) and both had the ability to walk on land.
The turtle also had a long tail, which was used to propel it through the water. In addition, both turtles and dinosaurs had feathers on their backs and necks, as well as a pair of wings on each side of their bodies. They also both used their tails to help them swim. And, of course, all of these features are found in birds and reptiles today.
Are chickens related to T. rex?
The analysis of a shred of a 68-million-year-old tyrannosaurus rex, along with that of 21 modern species, confirms that dinosaurs share common ancestry with birds. The study, published today in the Proceedings of the National Academy of Sciences (PNAS), is the first to show that birds and dinosaurs shared a common ancestor that lived during the Cretaceous period, about 65 million years ago.
The study also shows that modern birds are more closely related to dinosaurs than previously thought, according to the study’s lead author, University of Chicago paleontologist David Evans, Ph.D. “This is a major step forward in our understanding of dinosaur evolution,” Evans said.
Is a Komodo dragon a dinosaur?
Komodo dragon is a living dinosaur and the world’s largest lizard. Komodo dragons can grow up to 3-4 metres in length and weigh over 100 kilogrammes.
What was the last dinosaur to live?
Today’s birds are descendants of ancestors that didn’t just survive this mass extinction but evolved into thousands of new species. “This is the first time we’ve ever seen such a large number of species,” said study co-author David Evans, a paleontologist at the University of Bristol in the U.K.
What did alligators evolve from?
The first alligator ancestors evolved some 245 million years ago. crocodilians appeared around 80 million years ago. The alligatoroids, as well as their close relatives the crocodiles, alligators, and gharials, are included in this group. Crocodiles are the largest land animals on Earth. The largest crocodile ever recorded was a 30-foot-long specimen that was found off the coast of South Africa in 1996.
