Troodon Were Among The Most Intelligent Dinosaurs
Due to its high encephalization quotient (EQ), which compares brain size to body size, Troodon is often considered one of the more intelligent dinosaurs. This feathered predator lived in North America during the Cretaceous period. However, Dr. Lacovara suggests that while paleontologists use EQ to estimate intelligence, it's an approximate measure, and dinosaurs essentially possessed the brainpower they needed to survive.
Dinosaurs Didn't Give Us Oil
The vast oil reserves we utilize today actually originate from ancient marine plankton, not from dinosaurs. According to paleontologists, the sheer volume of petroleum found globally could not have been produced by the total mass of dinosaurs that ever existed. This understanding corrects a common misconception about the source of fossil fuels.
Velociraptors More Likely Had Feathers Than Scales
Scientific evidence suggests that Velociraptors were likely covered in feathers, not scales as commonly depicted. This characteristic is also believed to be true for Deinonychus, another dinosaur species. This understanding shifts the visual representation of these creatures from reptilian to more bird-like.
It Is Estimated That 65 Million Years Ago Is When Dinosaurs Became Extinct
The leading theory for the dinosaurs' demise points to a massive asteroid impact, though large-scale volcanic eruptions and gradual climate shifts may have also played significant roles. This major extinction event, which occurred approximately 65 million years ago, is still a subject of ongoing scientific study. The combination of these factors likely led to the end of the dinosaurs' reign.
Hadrosaurs Were Much More Dangerous Than We Think
Despite common portrayals of Hadrosaurs as gentle, approachable creatures, paleontologist Dr. Lacovara warns that these duck-billed dinosaurs were, in fact, dangerous. He emphasizes that the idea of them being friendly "gentle giants" is a misconception and that no dinosaur should be considered safe. According to Dr. Lacovara, an encounter with a Hadrosaur in reality would likely be perilous.
Most Dinosaurs Could Fend For Themselves As Soon As They Hatched
Certain dinosaur species, such as titanosaurs, were precocial, meaning their young were self-sufficient almost immediately after hatching, much like an antelope calf today. This contrasts with other dinosaurs whose offspring were altricial, born helpless and entirely dependent on parental care, similar to a baby robin. This variation in early development highlights different survival strategies among dinosaur groups.
Dreadnoughtus Could Crush Predators Under Their Colossal Weight
Weighing an estimated 65 tons, the massive Dreadnoughtus was so colossal that it could overpower even formidable predators like a T-Rex simply by using its immense weight. This makes it about nine times heavier than a T-Rex and roughly ten times heavier than a Boeing 737. Its sheer size meant it could crush its adversaries, for instance, by pressing a T-Rex against a tree.
The Argentinosaurus Was The Biggest Dinosaur To Live On Land
Reaching lengths of up to 40 meters and standing as tall as 21 meters, the Argentinosaurus holds the distinction of being the largest known dinosaur to have lived on land. To put its immense scale into perspective, an average blue whale measures only about 4 to 5 meters long. This truly massive herbivore was a colossal presence in its environment.
"Dinosaur" Comes From Greek
The name "dinosaur" itself comes from two Greek words: "deinos," meaning terrible, and "sauros," which translates to lizard. Thus, the term directly means "terrible lizard," a fitting description for formidable species like the T-Rex, even if not all dinosaurs were aggressive carnivores. This Greek origin provides the well-known classification for these ancient creatures.
The Longest Dinosaur Name Is Micropachycephalosaurus
With a genus name consisting of 23 letters, Micropachycephalosaurus holds the distinction of having the longest dinosaur name. When its full scientific binomial is considered, the letter count impressively reaches 37. This lengthy name makes Micropachycephalosaurus notable in paleontological records.
Herbivores Made Up A Large Portion Of The Biggest Dinosaurs
Many of the most massive dinosaurs to ever exist, such as the Brachiosaurus and Apatosaurus, were actually plant-eaters. These enormous creatures sustained their huge bodies solely with a vegetarian diet.
Ankylosaurs Probably Fought Each Other With Their Club Tails
The prominent tail clubs of Ankylosaurs likely played a significant role in conflicts between individuals of the same species. While these bony appendages could also have served as a defense against predators, recent research indicates that competition among Ankylosaurs themselves may have been the primary driver for the evolution of this iconic feature. Thus
Dinosaurs Were Wiped Out By An Asteroid
The prevailing scientific theory attributes the extinction of the dinosaurs to the impact of a massive asteroid. Evidence of this cataclysmic event includes a colossal crater, approximately 110 miles (or 180 kilometers) wide, situated off the coast of Mexico. This impact event is understood to have caused widespread devastation, ultimately leading to the end of the dinosaurs' reign.
We Don't Really Know What Colors Dinosaurs Were
The exact colors of dinosaurs remain largely unknown to scientists. To make educated guesses, researchers often look at the coloration of very large animals alive today, such as whales, hippos, and rhinoceroses. Since these modern giants tend to be gray or have otherwise subdued, drab colors, it's probable that many of the enormous dinosaurs shared a similar, less vibrant appearance.
Dinosaurs Ate All Kinds Of Things
The dietary habits of dinosaurs were quite varied, with some species consuming only plants as herbivores, while others were meat-eaters, known as carnivores. Additionally, certain types of dinosaurs were omnivores, meaning their diet included both vegetation and animals. This diversity in food sources was a key feature of prehistoric ecosystems.
Dinosaurs Roamed All Of Earth, Even Belgium
Dinosaurs inhabited every part of the globe, with their remains found even in places like modern-day Belgium, because their reign began when Earth's landmasses were joined as the supercontinent Pangea around 230 million years ago. Throughout the 165 million years that dinosaurs existed, this massive landform gradually broke apart. The ongoing process of plate tectonics drove this continental drift, eventually scattering dinosaur habitats across the forming continents we recognize today.
