Discover the Mesozoic Era: Top 12 Jaw-Dropping Fun Facts About the Jurassic Period

1. Turkey-Sized Dinos

If Jurassic Park had a turkey dinner, they'd invite these little dinos: during the Jurassic Period, not all dinosaurs towered over the earth – in fact, some, like the hypsilophodontids, were not much larger than turkeys, and their herbivorous diet and agility made them essential players in maintaining a balanced ancient ecosystem.

2. Stegosaurus Fashionista

Stegosaurus was the Jurassic's ultimate fashionista, turning heads with ostentatious back plates they styled to impress like a prehistoric peacock: Scientists theorize that these bony plates functioned as display structures, possibly to attract mates or identify fellow Stegosaurus, rather than serving any camouflaging or protective purpose.

3. Allosaurus: Jurassic Top Dog

Step aside, T-Rex wannabes: the Allosaurus jimmadseni was the top dog of the Jurassic period, stomping around with its super long, 26 to 29-foot bod and all its 4,000 pounds of prehistoric swagger! This fearsome meat-lovers' mascot made sure every dino knew who was boss with its fierce claws and teeth that would give a horror movie villain nightmares – oh, and the fact that it might have snacked on spiky-tailed Stegosaurus? Pure Jurassic gossip! But wait, there's more: A. jimmadseni was not just any old Allosaurus – it's actually the oldest species of Allosaurus discovered to date, with only one other recognized species in the genus making the cut, amidst heated paleontological debates regarding the existence of up to 12 separate species. So raise a glass (or a talon) to the original beast of the Jurassic world!

4. Feathered theropod Fashion

Think the latest fashion trends are hard to keep up with? Try being a stylish theropod during the Jurassic Period: Small carnivorous dinosaurs sported feathers for insulation, not flight, suggesting some of them were warm-blooded party animals, just like their descendants – the birds.

5. New Flaptastic Fossil

Move over, Archaeopteryx – there's a new flaptastic fossil in town! This dino-bird has swooped in and ruffled feathers in scientific circles by pecking at previously cooped-up beliefs: Researchers have discovered a new bird-like dinosaur fossil, Alcmonavis poeschli, during the Jurassic period, which shows characteristics similar to modern birds and implies that it was better adapted for flapping flight. This unexpected find topples the notion that Archaeopteryx was the only known flying bird from that era, and offers fascinating insights into avian evolution.

6. Dino High School Cliques

Move over, high school cliques: Jurassic period dinosaurs had their own social hierarchies too! During the Jurassic Period, Mussaurus patagonicus, a plant-eating dinosaur ancestor of the sauropods, formed complex herds where eggs were communally nested, juveniles stuck together in "schools," and adults worked on providing for their scaly squad. This "age segregation" points to an organized, herd-like social structure existing as early as 193 million years ago, not just in herbivores, but in some meat-eating dinos as well. Beware the teen T-rexes roaming the halls!

7. Dinosaurs Wore Fur First

In a fashion statement that would make any fashionista quiver with envy, dinosaurs from the Jurassic period dabbled in fur before it became trendy on today's catwalks: Ornitholestes, a small theropod dinosaur, might have sported a fabulous downy covering of hair-like feathers, as initially suggested by Percy Lowe in 1944. Recent fossil discoveries in China have added weight to this chic theory, prompting modern paleontologists to seriously consider these fierce feathered theropods as the original style icons.

8. Jurassic Greenhouse Rave

If the Jurassic Period were a party, it'd be a greenhouse rave with a high CO2 fog machine and an O2 bounce house: During this time, carbon dioxide levels soared up to 1900 ppm, over seven times the preindustrial level, and average oxygen levels inflated to 26%, which was 130% of today's level. This wild prehistoric bash led to global mean temperatures rising 6-9°C warmer than present day and the ultimate breakup of Pangaea, giving birth to the Atlantic and Indian oceans.

9. Land Before Time IRL

Hold onto your Jurassic hats and roar with laughter, for the sauropods and theropods of the Jurassic Period were the original "long-necks" and "sharp-tooths" from your favorite prehistoric animations: The Jurassic Period marked the emergence of new dinosaur species, including the herbivorous giants such as Brachiosaurus and Diplodocus, as well as formidable medium-to-large sized carnivores like Allosaurus and Megalosaurus, with the iconic T-Rex making a rare cameo in fossils dating back to the late Jurassic era.

10. Plesiosaurs' Double Soirée

In the age of fiesty fin-flappers and waterborne behemoths, plesiosaurs were totally flexible - whether it's a saltwater soirée or a freshwater fiesta, these aquatic party animals always knew how to make a splash: Recent discoveries reveal that plesiosaurs thrived in both saltwater and freshwater environments during the Jurassic Period, indicating their impressive adaptability and debunking the myth that descendants of these creatures could still be swimming around as elusive Loch Ness Monsters today.

11. Pteranodon-Indominus Feud

Talk about a "flying" temper: When Pteranodon met Indominus Rex, the Jurassic Park playdate turned into a chaotic wing-flapping and dino-stomping extravaganza: During the Isla Nublar Incident of 2015, an irritated Indominus Rex crashed into the Pteranodon aviary while being pursued by a helicopter, inadvertently unleashing a flock of furious Pteranodons who wreaked havoc on unsuspecting park-goers.

12. Fearsome Pliosaur Predator

Move over, Jaws: there's a new, bigger, badder predator in town, and it's not a Spielberg concoction! It's a pliosaur from the Late Jurassic seas, known to reach a colossal size of 14.4 meters long – that's double the length of a killer whale. With a massive skull, protruding teeth, and a penchant for biting ichthyosaurs in half, this prehistoric marine monster certainly tops the list of things you wouldn't want to encounter during a midnight swim.
