The closest living relatives to dinosaurs are birds, which are dinosaurs (avian dinosaurs), having evolved from small, feathered theropods, but if you're looking for non-avian relatives that resemble prehistoric times, crocodilians (crocodiles, alligators, caimans) are the closest, sharing a common ancestor and having changed little in millions of years, along with other archosaurs like turtles, while birds like the cassowary are the most dinosaur-like in appearance and behavior.
The closest relatives of dinosaurs are birds Scientists now agree that birds alive today are living dinosaurs, directly descended from theropods (carnivorous dinosaurs that walked on two legs).
1. Crocodiles. 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).
They're still alive among us – in the form of birds! Learn about how birds survived the killer asteroid and became today's only living dinosaurs on NOVA l PBS' "Dino Birds," stream now on the PBS app!
“Dinosaurs are so old that there probably isn't any dinosaur DNA left on Earth,” Logan told Eye on Science. “Sure, if you were able to store DNA on the dark side of the moon, it could remain stable for millions of years. But on Earth, it cannot survive for long, even in permafrost.
The short answer is no. That's because DNA, the genetic code that makes up our genes and which dictate each creature's specific characteristics, degrades over time. The oldest DNA found in a fossil was one million years old.
In 2007, Nicolas Cage paid $276,000 at a Beverly Hills auction for a rare Tyrannosaurus bataar skull, outbidding Leonardo DiCaprio. The skull was later found to be illegally smuggled from Mongolia, where it's protected by strict cultural heritage laws.
If the answer is that 1) the dinosaurs lived and died before Adam and Eve, then we are consistent with evolutionary theory at least in the sense that dinosaurs lived long before humans.
It's doubtful. Tyrannosaurus Rex, and Triceratops for example, lived in the Cretaceous Period 145-66 million years ago (whatever Jurassic Park would have you believe).
Nigersaurus had so many teeth it has been dubbed "the mesozoic lawnmower," but while it may may have looked like "a hammerhead shark with legs," even it had a match.
Jonathan, a Seychelles giant tortoise living on the island of Saint Helena, is reported to be at least 193 years old, hence the oldest currently living terrestrial animal. If Adwaita's claim is not true, Jonathan might be the oldest known terrestrial animal to have ever existed.
Scripture does not mention the existence of dinosaurs—at least not as we now understand them—neither before nor after the Genesis Flood.
Sharks are ancient creatures that evolved long before dinosaurs lived on land. They have survived five global mass extinctions, each of which wiped out more than 75 per cent of animal species.
The woolly mammoth is the animal most prominently linked to a 2027 return, with biotechnology firm Colossal Biosciences aiming to have a cold-resistant elephant hybrid with mammoth traits walking the Earth by then, using gene-editing to help restore Arctic ecosystems. While not a true resurrection, this project aims to create a functional woolly mammoth-like creature, with other efforts also underway to de-extinct animals like the Tasmanian tiger (thylacine) and dodo.
Some geneticists also estimate that every person on planet Earth is at least a fiftieth cousin to everyone else. Family researchers may not see pedigree collapse for several generations, but inevitably it will pop up as you climb the family tree.
Pelycosaurs, like Dimetrodon, were early reptiles that thrived during the Permian period, before dinosaurs. Therapsids were mammal-like reptiles with powerful jaws that evolved during the early Permian period. Archosaurs were diverse reptiles that led to the first dinosaurs and still include crocodiles today.
The double dinosaur emojis (🦖🦖) primarily represent literal dinosaurs (like the T-Rex and Sauropod), but in internet slang, they often mean someone or something is old-fashioned, outdated, or “a dinosaur” that hasn't kept up with modern times, similar to calling someone out for using old tech or having outdated ideas. It can also just mean dinosaurs in general or be used playfully to call someone big and powerful, or even represent trans identities online.
Gizmodo reports the oldest sequenced DNA belongs to a million-year-old woolly mammoth. DNA is a relatively fragile molecule, and dinosaurs went extinct 65 million years ago, so the idea of sequencing DNA from these ancient creatures has so far remained science fiction.
It is unlikely that oxygen content would have any significant impact on dinosaurs brought to modern day.
Birds have the closest DNA to dinosaurs, as they are direct descendants of theropod dinosaurs, making them living dinosaurs; chickens and ostriches, in particular, share strong genetic links with T. rex, confirmed through protein analysis and shared physical traits like scales and bone structure. While crocodilians (alligators, crocodiles) are also close relatives, birds are the most immediate living link to the dinosaur lineage.
Probably not. The small proro-human mammals that survived the dinosaur killing impact would not have had the opportunity to spread as far and differentiate in a dinosaur filled world. Very likely mammals would still be small and in marginal niches if those apex dinosaur predators were still around.
On the one hand, some reject evolutionary science, while affirming the Genesis account of human origins. On the other hand, others reject Adam and Eve as real people in a real past, while affirming the evolutionary account of human origins.
The final cost was US$8,362,500, making it the most expensive fossil ever sold up until that time. Sue remains one of the most expensive dinosaur fossils ever sold, only surpassed in 2020 with the sale of Stan the T. rex. for $31.8 million, and subsequently in 2024 by Apex the Stegosaurus, which sold for $44.6 million.
