For years, scientists categorized dinosaurs as cold-blooded (ectotherms) or, more recently, somewhere in the middle (mesotherms). But new research looking at the chemistry of dinosaur eggshells reveals that these monsters of the Triassic and Cretaceous periods were warm-blooded (endotherms) creatures. Host Stefan Chin gives us more in this presentation from SciShow.

In a spellbinding presentation, Vancouver paleontologist Jack Horner explains what many perceive as shape-shifting dinosaurs are actually growth spurts in juveniles. The shocking secret, Horner says, was revealed by slicing into the fossilized skulls of these baby dinosaurs and comparing them to the adults. He explains further in this episode of Ted Talks.

Three characteristics dominate the legacy of Tyrannosaurus Rex: It was huge, vicious and had small arms. The story of how it lost those small arms is pretty simple, but why it kept the puny limbs is another tale. PBS Eons host Hank Green fills us in on the details.

Part of our fascination with dinosaurs is their size. Shaking the earth from the Jurassic to Cretaceous periods, some dinos reached the height of a five-story building. But how did they get so huge? And why did mammals get the short end of the stick? Host Hank Green has some answers in this edition of PBS Eons.

I am now convinced that every consumable given to us by the elite, represents some kind of mockery or evil. Opal Fruits (now Starburst) are no different. These vintage commercials disclose everything from chemtrails to fallen alien deception and depict children as “fruit” and “food” to the elite.
Opal is mined from Australia’s massive Great Artesian Basin GAB, from fossilized dinosaurs. Dragon tears (see urban dictionary for real meaning of man tears) are said to be the source of Starburst’ peculiar juiciness. Things get really weird when a commercial shows children being chemtrailed with Opal Fruits under pink skies! More from EntertheStars Reloaded.

Humans and dinosaurs are never associated with each other, because science tells us they supposedly lived in completely different time periods. The dinos were prehistoric reptiles that evolved during the middle-to-late Triassic Period of the Mesozoic Era 230 millions years ago, while humans have been around for a mere 200,000 years. Beyond Science host Mikey Chen analyzes five clues that might prove otherwise.

Now that some evidence is emerging that T-Rex might have had red feathers and been an oversized relative of the chicken, inquiring minds want to know: Was the big beast even a dinosaur? Or might it have been a 40-foot-long, eight-ton bird?

Have you ever wondered what dinosaur meat might have tasted like? Chances are you’ve eaten dinosaur more recently than you might expect. More from the SciShow.

Scientists have debated for decades whether dinosaurs were warm-blooded creatures or cold-blooded killers. Host Michael Aranda says that it turns out dinos were somewhere in the middle. He helps solve the metabolism puzzle for these magnificent creatures in this edition of SciShow.
