Crocodiles are not dinosaurs, but both crocodiles and dinosaurs came from the crown group Archosaurs. Birds, crocodiles, pterosaurs, and dinosaurs were part of the archosaurs. The last 65 million years have seen the evolution of modern-day birds.
The crocodile is a member of the family Crocodyliformes, which includes all crocodilians, including alligators, caimans, alligator-like reptiles, lizards, snakes, turtles, birds and mammals. They are the largest land animals on Earth and are found in tropical and subtropical regions around the world.

Are alligators The closest thing to dinosaurs?
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.
Why is a crocodile not a dinosaur?
Their thigh bones are very close to the ground. They are running with a side-to-side motion. Dinosaurs also had a long neck, which allowed them to hold their breath for long periods of time. The neck of a crocodile, for example, can hold a person underwater for up to 30 minutes.
What is the closest living thing 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.
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.
Are chickens related to T rex?
Putting more meat on the theory that dinosaurs’ closest living relatives are modern-day birds, an analysis of a shred of a 68-million-year-old tyrannosaurus rex shows that dinosaurs share common ancestry with chickens. “This is the first time that we’ve been able to show that birds and dinosaurs shared a common ancestor,” said study co-author David Evans, a paleontologist at the University of Edinburgh in Scotland.
Is a turtle a dinosaur?
According to a new study, sea turtles are living dinosaurs, having lived for 90 million years before dinosaurs went extinct.
The study, published in the Proceedings of the National Academy of Sciences (PNAS), found that the turtles, which are found in tropical and subtropical waters around the world, are the only animals known to have survived the mass extinction event that wiped out most of all life on Earth.
The study was conducted by a team of researchers at the University of California, Santa Cruz, and the Smithsonian Institution’s National Museum of Natural History in Washington, D.C., and was funded by the U.S. National Science Foundation (NSF) and National Oceanic and Atmospheric Administration’s (NOAA) National Marine Fisheries Service (NMFS) Marine Mammal Stranding Network (MMSN) in partnership with NOAA Fisheries and NOAA’s Office of Ocean Exploration and Research (OER).
Is a shark a dinosaur?
According to the data reported on fossil records, sharks have been around for more than 450 million years ago, while dinosaurs have been around for less than 200 million years ago. It’s clear that sharks arrived first before dinosaurs. The study was published in the Journal of Vertebrate Paleontology.
