Were Dinosaurs Warm-Blooded?
Although many people think the issue has been settled once and for all, scientists still debate whether dinosaurs were warm-blooded or cold-blooded (or something in between). Here's a look at the evidence for and against warm-blooded dinosaurs.
T. Rex - Hunter or Scavenger?
Did Tyrannosaurus Rex actively hunt for its food, did it scavenge already dead (or dying) prey, or did it pursue both behaviors at once? Paleontologists have been debating this issue for decades, and there's no clear answer one way or the other.
Did Dinosaurs Have Arthritis?
Consider it the Jurassic equivalent of an urban myth: dinosaurs suffered from arthritis, the same way people do. Is there any truth to this belief?
What Can Dinosaurs Tell Us About Global Warming?
Both sides in the global-warming debate--those who believe human beings are helping to accelerate climate change and those who insist it's all a natural process--invoke the fate of the dinosaurs 65 million years ago to back up their arguments. Who's right?
Does Oil Come From Dinosaurs?
Many people mistakenly believe that oil comes from long-decomposed dinosaurs--and at least one prominent oil company has contributed to this myth by adopting a dinosaur as its trademark. Here's the truth about what dinosaurs do, and don't, have to do with the world's supply of fossil fuels.
Dinosaurs, Reptoids and Reptilians
According to a popular conspiracy theory, super-intelligent humanoid reptiles (usually called reptoids or reptilians) are secretly pulling the strings of world affairs. What do these scaly green super-villains have to do with dinosaurs?
Why Did T. Rex Have Such Tiny Arms?
As relentless a killing machine as Tyrannosaurus Rex was, this dinosaur was still equipped with tiny, almost vestigial arms. Why did T. Rex have such small arms and hands, and what did (or didn't) it do with these almost comical-looking appendages?
Was Archaeopteryx a Bird or a Dinosaur?
Archaeopteryx is often described as the first bird, but the truth is considerably more complex than that. The question is, was Archaeopteryx closer to being a bird than it was to being a dinosaur, and what does this tell us about the evolutionary link between dinosaurs and birds?
Why Did Stegosaurus Have Plates on its Back?
It's one of the two or three most popular dinosaurs that ever lived, yet paleontologists still don't fully understand the function, or even the precise arrangement, of Stegosaurus' plates. Here's a look at our current state of knowledge.
Is Mokele-Mbembe Really a Dinosaur?
For the last 200 years, stories have circulated about a vaguely dinosaur-like beast haunting Africa's Congo River basin. Does the Mokele-mbembe really exist, or is it simply a mythical creature that some foolish cryptozoologists insist still haunts the rain forest?
Why Did Spinosaurus Have a Sail?
Not only was Spinosaurus the largest carnivorous dinosaur that ever lived, outweighing Tyrannosaurus Rex by one or two tons, but it was also the only plus-sized theropod of the Mesozoic Era to be equipped with a prominent sail. The question is, why?
Can We Clone a Dinosaur?
Ever since Jurassic Park, people have wondered if it will one day be possible to clone a living, breathing dinosaur out of preserved DNA (possibly recovered from fossilized amber). Trouble is, the scientific challenges are much heftier than you've been led to believe.
Is the Loch Ness Monster Really a Marine Reptile?
People who insist the Loch Ness Monster really exists say it looks like a long-extinct plesiosaur, a type of marine reptile, or even a sauropod with a marine lifestyle. Do they have a leg (or flipper) to stand on, or are they simply perpetuating the Loch Ness myth?
Dinosaurs and Dragons
Dragons--or dragon-like monsters--are a common feature of folk tales around the world, especially in Europe, central America and the Far East. Could these mythical, monstrous "dragons" actually be references to long-extinct dinosaurs?
De-Extinction - The Resurrection of Extinct Animals
With new advances in DNA technology, it may be possible to "de-extinct" animals that disappeared off the face of the earth hundreds, or even thousands, of years ago. But just because de-extinction is achievable, does that mean we should do it?
The Top 10 Candidates for De-Extinction
Ten recently extinct mammals, birds and amphibians that are ripe for de-extinction--and introduction back into the wild.
De-Extinction in 10 (Not So Easy) Steps
Do you want to know what, exactly, is involved in de-extincting a long-vanished species? Here's what the process looks like, in 10 easy (or not-so-easy) steps.
Could Dinosaurs Swim?
Virtually every terrestrial animal alive today knows how to swim, which means dinosaurs did, too. But do we have any solid proof of swimming dinosaurs?
Can We Clone a Woolly Mammoth?
Since Woolly Mammoths are often found preserved in 10,0000-year-old permafrost, they would seem to be ideal candidates for cloning and reintroduction into the wild. But how close are we to actually engineering, gestating and raising a living, breathing Mammoth?
10 Facts About the Loch Ness Monster
The Loch Ness Monster is often identified as a sauropod dinosaur, or a type of long-extinct marine reptile known as a plesiosaur. What do we really know about this supposed Scottish "monster," and how do the legends match up with the established facts?
Can Christians Believe in Dinosaurs?
There are lots of things about dinosaurs in particular (and evolution in general) that run counter to Christian theology--which bothers some Christians more than it does others. Can you be a good Christian and believe in dinosaurs at the same time?
