Some people call Alligators “living fossils” because they look like dinosaurs but you may be surprised to learn that alligators are not actually dinosaurs. Alligators are classified as archosaurs, which is a group that includes both dinosaurs and their closest living relatives, such as birds.
Are alligators and dinosaurs related?
Alligators are not dinosaurs, though they belong to the same order as dinosaurs once did. Their ancestors were closely related to dinosaurs and walked the earth at the same time. While dinosaurs went extinct, alligator ancestors went on to evolve into the alligators we see on Earth today.
What is the closest relative to a dinosaur?
The closest living relatives of ALL dinosaurs are the crocodilians (crocodiles, alligators, gharials). The wording is a little misleading in the question. Birds *are* dinosaurs in the same way that humans are mammals.
What animal is closely related to alligators?
Alligators, Crocodiles, caimans, and gharial are related, but are different species. Gators have a wide rounded “U” shaped snout that packs more crushing power to eat prey like turtles. Croc's have “V” shaped snouts. The Croc will have visible teeth when its mouth is closed.
What is the closest living relative to alligators and crocodiles?
It may seem hard to find two animals more different than a hummingbird and an crocodile But as strange as it may be, birds and crocodilians (the group containing alligators, crocodiles and gharials) are each other's closest relatives.

Who would win in a fight between an alligator and a crocodile?
Alligator vs. Crocodile: Who Would Win in a Fight? Crocodiles win the fight because they're bigger, stronger, and more aggressive than alligators.
Do alligators and crocodiles mate?
Crocodiles can not mate with alligators. The quick answer is no. Despite having a similar appearance, they are genetically too different, and although related, they long ago diverged into different genera.
What dinosaur did alligators evolve from?
Birds and alligators are both descendants of the archosaur, a creature that came before the dinosaurs, about 246 million years ago. The archosaur eventually evolved into two separate species — one that led to the creation of alligators, and another to dinosaurs.
What did alligators evolve from?
Today's alligators and crocodiles are members of a broader, older group of reptiles known as the Pseudosuchia. This is the 'crocodilian line' which split from the 'bird line', including dinosaurs, birds and pterosaurs – an extinct group of flying reptiles and the earliest vertebrates to have evolved powered flight.
Do alligators have a predator?
Juveniles: Small alligators are eaten by a variety of predators including raccoons, otters, wading birds, and fish; however, larger alligators may be their most significant predator. Adults: Cannibalism, intraspecific fighting, and hunting by humans are probably the most significant mortality factors.
What animal DNA is closest to dinosaurs?
Crocodilians are the most closely related group. They evolved before dinosaurs and experts put crocodiles in the larger family group, archosaurs. Strictly speaking, birds are the only direct descendants of the giant, extinct dinosaurs, and crocodiles and alligators are close relatives.
Did humans live with dinosaurs?
No! After the dinosaurs died out, nearly 65 million years passed before people appeared on Earth. However, small mammals (including shrew-sized primates) were alive at the time of the dinosaurs.
Are chickens related to T Rex?
The closest living relatives of Tyrannosaurus rex are birds such as chickens and ostriches, according to research published today in Science (and promptly reported in the New York Times). Paleontologists used material discovered in a chance find in 2003 to pin down the link.
What dinosaur is closest to a alligator?
Deinosuchus had an alligator-like, broad snout, with a slightly bulbous tip. Each premaxilla contained four teeth, with the pair nearest to the tip of the snout being significantly smaller than the other two.
Do crocodiles share DNA with dinosaurs?
This is what you came for: big, scary reptiles, right? Well, crocodiles share a heritage with dinosaurs as part of a group known as archosaurs (“ruling reptiles”), who date back to the Early Triassic period (250 million years ago).
Are crocodiles related to Trex?
They confirmed that the giant predator is closely related to chickens and ostriches, but only to a lesser extent to reptiles such as alligators and crocodiles, which were thought to be more closely related to dinosaurs than other living creatures.
How did alligators survive the asteroid?
This is a great question, and one many scientists have asked. There are two main reasons. First, crocodiles can live for a very long time without food. Second, they lived in places that were the least affected when the asteroid hit Earth.
Why did alligators stop evolving?
Surviving crocodiles did not change throughout millions of years because they arrived at an equilibrium where they were efficient and versatile enough that they did not need to evolve to exist, reports the Conversation.
What killed the dinosaurs?
Evidence suggests an asteroid impact was the main culprit. Volcanic eruptions that caused large-scale climate change may also have been involved, together with more gradual changes to Earth's climate that happened over millions of years.
Are alligators evolving?
While modern alligators do look prehistoric, study authors say they are not somehow immune to evolution. On the contrary, they are the result of an incredibly ancient evolutionary line.
Are Komodo dragons dinosaurs?
It is a reptile, a not-to-distant relative of the snake; both animals share a forked tongue. Dragons can reach 10 feet in length, and weigh as much as 300 pounds. Though it resembles one, the Komodo is not a direct descendant of the dinosaurs.
Can alligators bond with humans?
Dinets observed a juvenile alligator playing with a river otter. In rare cases, individual crocodilians have been known to bond so strongly with people that they become playmates for years. For example, a man who rescued a crocodile that had been shot in the head became close friends with the animal.
Which is more aggressive alligator or crocodile?
Typically, crocodiles are more aggressive than alligators, which makes crocodiles more dangerous than alligators. Alligators are opportunistic feeders, meaning that they're not likely to chase you down unless they're provoked. However, that certainly doesn't mean that you should swim with them.
Why are crocodiles so aggressive?
Crocodiles are apex predators and are known to attack humans when they feel threatened or provoked. Some of the reasons why crocodiles attack humans include: Protecting their territory or young. Defending their food source.
