Day 8: When it comes to the biggest predators of all time, everyone thinks T-Rex is the undisputed king. But what if I told you there was a dinosaur that might have been even bigger? Enter Giganotosaurus, the massive predator from South America that could challenge T-Rex for the throne.
I had one goal when I set out to photograph a Giganotosaurus: prove that size isn’t everything. What I didn’t expect was to come face-to-face with one and realize that maybe size really does matter.
Quick Facts About Giganotosaurus
Here’s what makes this predator so fascinating:
- Name Meaning: Giganotosaurus means “giant southern lizard.”
- Time Period: Lived about 98 million years ago during the Late Cretaceous.
- Size: Up to 43 feet long and weighing around 8 tons—longer than T-Rex but slightly lighter.
- Diet: Carnivore, preying on large herbivores like Argentinosaurus.
- Habitat: Lived in what is now Argentina, in a warm, semi-arid climate.
Max’s Encounter: Big Trouble
The day started off relatively quiet. I’d tracked Giganotosaurus footprints for hours, their size making them easy to follow through the dry, dusty landscape. When I finally found one, it was standing on a rocky outcrop, its silhouette framed by the blazing sun. It was huge, with a long snout and teeth that gleamed even from a distance.
I positioned myself behind a boulder to get the perfect shot. Just as I raised my camera, the wind betrayed me—again. The Giganotosaurus froze, sniffed the air, and turned its head in my direction.
It was faster than I expected. One moment it was on the outcrop; the next, it was stalking toward me. My heart felt like it was going to burst as I scrambled up the rocks, my camera swinging around my neck. Thankfully, Giganotosaurus wasn’t hungry—it was curious. It sniffed the ground where I’d been crouching, let out a low growl, and moved on. Crisis averted… barely.
Giganotosaurus vs. T-Rex: Who’s the Real King?
- Size
Giganotosaurus was slightly longer than T-Rex, but it wasn’t as bulky. While T-Rex had a bone-crushing bite, Giganotosaurus relied on speed and slicing teeth. - Speed
Giganotosaurus could run up to 31 miles per hour, faster than T-Rex, which maxed out at around 20 miles per hour. - Hunting Style
Unlike T-Rex, which was a solo hunter, Giganotosaurus may have hunted in packs to take down massive prey like Argentinosaurus, the largest dinosaur ever discovered.
Did You Know?
- Giganotosaurus teeth were serrated, like steak knives, perfect for slicing through flesh.
- Its brain was smaller than T-Rex’s, meaning it may not have been as smart.
- Fossils suggest it lived in an area filled with giant herbivores, making it one of the top predators of its ecosystem.
Real Giganotosaurus Pictures
The photo I managed to snap is one of my best yet: the Giganotosaurus standing tall, its tail stretched behind it, with the sun setting in the background. Sam says it looks like a movie poster. I say it’s proof that this predator could rival T-Rex any day.
[Dinosaur pictures are coming soon, just waiting for the film to develop!]
Field Notes From Max
- Survival Tip: Stay downwind. Giganotosaurus might not be as aggressive as T-Rex, but you don’t want to push your luck.
- What I Learned: Speed and strategy make Giganotosaurus just as formidable as the bulkier T-Rex.
- Favorite Moment: Watching it stalk a group of smaller dinosaurs like a cat chasing birds.
The Bigger Picture
Giganotosaurus proves that there’s more to being an apex predator than just size. Its speed and slicing teeth made it perfectly adapted to its environment. Back home, scientists love to pit T-Rex against Giganotosaurus in the ultimate dino showdown. My photos might not settle the debate, but they’ll definitely get people talking.
Sam, of course, has other ideas. “If you’re going to risk your life for pictures, at least pitch it to a streaming service,” she said. “Dinosaurs vs. Time Traveler—sounds like a hit to me.” Honestly? Not the worst idea she’s had.

Brachiosaurus might be a gentle giant, but it’s still a lot less gentle when it accidentally sneezes on you. Stay tuned for the story. 🦖🦕
