Recent Discoveries Change How We Think about Dinosaurs

Five new discoveries has re-shaped how scientists and a ubiquitous open perspective dinosaurs.

Dinosaurs are cool. That’s not adult for debate. But, even yet a ancient lizards have been archaic for 65 million years, there’s still copiousness of exciting, new investigate severe a things we consider we know about dinosaurs. Over a past few years alone, a slew of studies have unclosed sum about antiquated life formerly opposite to science.

1. Triceratops had a badass relations named Hellboy

Scientists stating in Current Biology recently detected a new class of dinosaur, Regaliceratops peterhewsi (nicknamed “Hellboy” for a “devilishly hard” labor of excavating a skull and for a similarity to a comic book superhero of a same name).

After scarcely 2 years spent digging adult a dinosaur’s bones, a researchers satisfied that they’d found a new species, a vegetarian relations of Triceratops that lived around 70 million years ago. Characterized by a hulk horn above a nose and a crown-like ring of bony plates atop a forehead, a mature Hellboy was so vast that even a T. rex wouldn’t have been a hazard to it.

2. T. rexes were cannibals

And vocalization of T. rex, scientists stating in a biography PeerJ detected in Apr that Tyrannosaurs were many expected cannibals. After examining a skeleton of a immature Daspletosaurus, a member of a Tyrannosaurus family closely associated to T. rex, scientists satisfied that many of a injuries postulated by a passed dino were caused post-mortem.

In other words, some of a injuries seen in a skeleton competence have been what caused a Daspletosaur’s death, though after it was already passed another Tyrannosaur came along and ate partial of it. Yikes.

3. Velociraptors were…feathered?

Yep, we review that correctly. Despite what a Jurassic Park cinema competence show, Velociraptors were many expected lonesome in feathers, some-more bird-like and reduction dragon-like than we’d thought.

We know this interjection to a new investigate published in Scientific Reports, in that scientists analyzed a unusually well-preserved skeleton of Zhenyuanlong suni, a 5-foot-long, 25-pound relations of Velociraptors. Like a Velociraptor, Z. suni was a dromaeosaurid—a fast-running, feathered, sickled-clawed dinosaur closely associated to birds.

Sadly, notwithstanding carrying feathered wings like a bird, a scientists don’t consider Z. suni’s short, 14-inch wings could have carried it off a ground.

4. There might’ve been warm-blooded dinosaurs

We tend to consider of dinosaurs as reptilian and cold-blooded, though in fact, new investigate in Science indicates that some dinosaurs were warm-blooded (endothermic) mammals. The researchers wondered whether, given modern-day birds are endotherms, and birds are closely associated to dinosaurs, dinosaurs competence have been endotherms, too. So they complicated a dinos’ expansion rates and found that a antiquated beasts grew usually as quick as mammals, indicating that they were many expected warm-blooded creatures.

In fact, prior studies on dinosaurs’ teeth, appetite rates, and appetite expenditure have also found justification ancillary this theory. However, not all paleontologists are convinced—some still say that, formed on anniversary metabolism and information from non-avian species, dinosaurs tumble into a difficulty somewhere between endotherms and ectotherms. There’s some flattering exhilarated (zing!) discuss about this topic—in a dinosaur world, this subject is roughly as argumentative as a Pluto-(not)-being-a-planet issue.

5. The equator was no antiquated paradise

When we consider of areas tighten to a equator, we consider of pleasant paradises like a Caribbean. Who wouldn’t wish to live there? But 200 million years ago, a Jun PNAS investigate shows, it was a opposite story.

Extreme droughts, heated heat, and prevalent wildfires (similar to stream continue along a West Coast of a United States, in fact) prevented many class of dinosaurs from vital nearby a equator, explaining because paleontologists have historically usually found a skeleton of small, insatiable two-legged dinos in these areas. These resource-limited conditions could not support a different village of vast dinosaurs like a Brontosaurs or a Tyrannosaurs, so those class were driven to some-more ascetic areas during aloft altitudes.

So, if Jurassic Park ever does come true, during slightest we know you’re protected in California.
