11. An Extraordinary Amount of Tyrannosaurus Rexes Roamed The Earth

We’ve all seen the movies with dinosaurs and how much destruction a T-rex can cause. Could you imagine a total of 2.5 billion roaming the Earth? It’s crazy to think about, but that’s how many were roaming during the Cretaceous period. That’s many dinosaurs, and it’s a wonder that any other types of dinosaurs survived during that time! A study by UC Berkeley released in 2021 posited that because these dinosaurs lived and died for more than 2.5 million years, that at least 20,000 existed at any given time. That gives a total of 2.5 billion T. Rexes during those 2.5 million years.

It really is a wonder that any other type of dinosaur survived with the T. Rexes capability for violence and destruction. UC Berkeley has made strides in the paleontology department using Dalmuth’s Law. If you’re wondering how they made these calculations to determine how many T. Rexes roamed the Earth, scientists used Dalmuth’s Law. This particular law allows scientists to use the population density and body mass of a dinosaur to determine how many lived during a specific amount of time. Since science can never be exact, 2.5 billion is an estimation. However, experts believe the numbers could range from 140 million to 42 billion during the cretaceous period.

10. A Burial Site With A Shocking Discovery Made Headlines

It’s difficult to learn everything we need to know about dinosaurs without living specimens, so scientists do what they can with fossils found during excavations. These fossils give them information we would have never known. Could you imagine what we would learn from dinosaurs if they were living today? A shocking find at the Colorado – Utah border led scientists to believe some dinosaurs may have been cannibals. A paleontologist by the name of Stephanie Drumheller-Horton and her team discovered 2,000 bones with a peculiar look to them. Over 28% of the bones found had scratches, punctures, and bites, leading Stephanie and her team to believe the unthinkable.

That’s right. Other carnivorous dinosaurs cannibalized the bones. The discovery led scientists to believe in the possibility of cannibalism with certain species of dinosaurs. Scientists and paleontologists believe the reason behind cannibalism could have had something to do with the weather changes at the time. If there weren’t enough food sources available, some dinosaurs could have cannibalized their dead to survive the dry season. While it’s possible meat-eaters scavenged these fossils, the likelihood of cannibalization remains a possibility. You’ll be surprised by all of the new information available! Keep reading to learn more dinosaur facts you never learned in school.

9. A New Discovery For The T. Rex Species Could Lead to New Information

Paleontologists in Canada made a discovery in 2010 that led to a new type of Tyrannosaur called ‘The Reaper of Death.’ This new species was the first discovered in fifty years in Canada. It predates the T. Rex by at least twelve million years. Its technical name is Thanatotheristes degrootorum, which translates from Greek to mean Reaper of Death. A Ph.D. student by the name of Jared Voris find this fossil. He first saw fossils in the Royal Tyrrell Museum that didn’t look like a typical T. Rex skull. The skull had vertical ridges along the jawline that didn’t match any known species.

In 2010, when exploring the area surrounding the Bow River, Jared Voris found skull fragments. His advisor, Darla Zelenitsky, believes this Tyrannosaur is a new species different from the T. Rexes we all know from television and history books. This find is fantastic for Canada as a new species hasn’t been discovered in fifty years. It’s believed that The Reaper of Death roamed the Earth 79 million years ago during the Late Cretaceous period. Paleontologists believe this behemoth was at least 8 feet tall, weighing at least two tons. It also had 2.7- inch-long teeth used for tearing into the flesh of other dinosaurs, birds, and fish.

8. Are Dinosaurs Cold-Blooded Like Reptiles?

We still don’t know so much about dinosaurs, so is it possible they could have been warm-blooded? Scientists have speculated for years whether feathers play a role in the type of blood dinosaurs had. In fact, we now understand that most, if not all, dinosaurs had some kind of feathers. Paleontologists believe these dinos didn’t use their feathers to fly but for insulation against cooler temperatures. A 2020 study confirmed that three types of dinosaurs – the Ornithischia, Sauropodomorpha, and Theropoda – were warm-blooded. So, is it possible all dinosaurs were warm-blooded like these three? Scientists believe there are many reasons why they could have been. Keep reading to find out what those reasons are!

Some paleontologists believe dinosaurs had speedy metabolisms that would need warm blood to survive. Other aspects of their reasoning include some dinosaurs’ large sizes. Their size leads researchers to believe they could have been warm-blooded. While the topic is still up for debate, one thing is for sure – much research is needed to prove this theory and help us better understand every species of dinosaurs. If you found this interesting, keep reading to learn more facts scientists have discovered since you graduated from school.

7. Did You Know The Tyrannosaurus Rex Has Relatives?

That’s right! A species of dinosaur was discovered around 20 years ago that resembles the T. Rex. There’s one catch, however. The new species found by paleontologists is much smaller than the T. Rex we all recognize today. Its name is Suskityrannus hazelae, and it lived over 92 million years ago. This tiny dinosaur was three feet tall and had similar features to a T.Rex. Discovered in New Mexico by paleontologists, Suskityrannus hazelae may help to build the Tyrannosaurus family tree. This new information will help scientists and researchers gain a better understanding of prehistoric creatures. While the fossils found weren’t enough to gain a clear understanding, paleontologists are hopeful that more discoveries are to come.

Sterling Nesbitt, one of the paleontologists to help discover the new dinosaur, works for Virginia Tech in the Paleontology department. He believes the fossils found in New Mexico will help scientists build the family tree and determine where Suskityrannus hazelae fits into the equation. Since the dinosaur was so small, it’s challenging to find one fully intact, leading to more difficulty understanding the creature. It’s believed Suskityrannus hazelae was carnivorous as one of the fossils was found with a partially digested lizard skull inside it. Tyrannosaurs from other parts of the world have helped to discover where Suskityrannus hazelae lands on the Tyrannosaur family tree.

6. What Do You Know About The Archosaur?

It’s interesting to think of the many different places dinosaurs lived during their time on Earth. Paleontologists have found fossils, right? That includes on the frigid continent of Antarctica. The Archosaur reigned over Antarctica more than 250 million years ago. Paleontologists discovered a fossil dating back 250 million years on the icy continent that helped them gain insight into the Archosaur. This dinosaur was similar to an iguana and was at least four to five feet long. Its technical name – Antarctanax shackletoni – means Antarctica King. The Antarctanax shackletoni lived during the Triassic period, some 251 million years ago.

The Antarctanax shackletoni lived when Antarctica was thriving with abundant plant life, unlike the freezing, barren land we know today. Researchers learned quite a bit from the fossils found in Antarctica. They found that the lizard lived on the ground because the bones in its feet did not show signs of burrowing or climbing. Scientists believe Antarctica had vast forests, warm temperatures, and abundant animals when Antarctanax shackletoni was alive. It’s incredible to think of such a barren place filled with forests, rivers, and even wildlife. It’s not something you would expect, that’s for sure!

4. These Behemoths Hunted In A Strange Way

The Tyrannosaurus Rex is one of the most well-known dinosaurs. You can find this giant on the big screen, in the toy aisle, and for various decorations and party themes. It’s a dinosaur we all know well, or so we thought. Did you know these monsters actually hunted in packs? Initially, these massive dinosaurs were lone hunters, but new evidence has emerged that may change the way we think. Fossils found in Utah at the Grand Staircase-Escalante National Monument tell us a different story. These fossils show that dinosaurs hunted in packs rather than alone. The fossils also indicate something about the way they cared for their young!

Scientists now believe that the Tyrannosaurus Rex was actually a social creature. In fact, this large dino probably even enjoyed the company of others, especially while hunting. We’re sure you can imagine how much easier it would be to take down prey when there’s a group of these behemoths instead of a lone hunter. Scientists came up with this shocking discovery by studying the fossils of four T. Rexes that were found near each other. Chemical analysis of the soil and fossils show they died around the same time, leading scientists and paleontologists to believe they were hunting together. Keep reading for more interesting dinosaur facts!

3. Let’s Talk About Growth Spurts

Like humans during their teenage years, dinosaurs went through growth spurts that helped them grow into the enormous dinosaurs we know today. The Tyrannosaurus Rex is no exception. A study published in Science Advances talks about T. Rexes going through growth spurts and growing into their full size during their teenage years. Scientists previously thought that the smaller T. Rexes were different dinosaurs entirely. Advancements in science have changed the way we look at these dinosaurs. Studies on two skeletons prove the growth spurt theory due to the size of the bones and their body structures. Keep reading to learn more about these growth spurts.

A paleontologist by the name of Steve Brusatte believes most scientists are unfamiliar with the growth spurt theory as it’s a relatively new idea. It’s amazing to think these dinosaurs went from tiny hatchlings to 19,000-pound behemoths. A growth spurt had to happen somewhere during their lives to make that happen, right? It was discovered that their teenage years were a likely age for the growth spurts to occur due to evidence from the bones studied. Originally thought to be Pygmy dinosaurs, these teenage T. Rexes have taught scientists and paleontologists much about their younger years. Keep reading for more interesting facts you never knew!

2. Scientists Discovered New Information About Connections Between Birds And Dinosaurs

A paleontologist named Takuya Imai made an important discovery in 2013 that changed the way we look at the evolution between dinosaurs and modern-day birds. They discovered an Early Cretaceous period bird in Japan, which was the first one to be similar to modern-day birds. They found the bird first outside of China and named it Fukuipteryx prima. This bird had an intact skeleton that was perfect for study. Nature magazine reported it in 2019. Since then, it has become an essential topic of discussion between paleontologists. It helps scientists to understand better how birds evolved.

They believed the bird skeleton was one year old when it passed away, leading scientists to understand better the bird and its connection to the period in which it lived. Finding this intact skeleton provides much-needed information about these primitive birds and their connection to modern-day birds. As an example, Fukuipteryx prima is similar to modern-day birds in that their tailbones are the same. It’s interesting to see the connections between birds that lived millions of years ago to the birds we see today. You never know when someone will find a new skeleton, giving scientists more information and a better understanding of how our world works.

1. A Scene From Jurassic Park Couldn’t Have Happened

We’re sure you all remember the scene from Jurassic Park where a Tyrannosaurus Rex outruns a Jeep. Well, we hate to be the bearers of bad news, but this couldn’t have happened. Scientists believed that the T. Rex couldn’t have run that fast due to the size of its legs. Paleontologists initially thought the T. Rex could have run upwards of 33 miles per hour, but that estimation has since been revoked. A study done in 2017 with computer models shows these vast dinosaurs couldn’t have run any faster than 12 miles per hour. That’s a bid difference from chasing down a Jeep in the movies!

It’s incredible to think of the advancements in science that bring us this new information. When we were in school, we learned all about dinosaurs. However, with new research over the years, the authors need to update their textbooks. That way, everyone can learn about the much-needed information and new findings that change the way we think of these prehistoric creatures. The T. Rex is one of the most well-known dinosaurs due to its size and appearance. Gathering new information will help scientists give us a clearer picture of how these dinosaurs lived. Hopefully, one day, we’ll have a better understanding of the way they lived, hunted, parented, and more.
