Day 11: You’d think a dinosaur with a built-in musical instrument wouldn’t be all that intimidating. That’s what I thought before I stumbled across a Parasaurolophus herd and learned just how loud—and terrifying—they could be. Let’s just say that if dinosaurs had marching bands, these guys would have been the brass section.
Quick Facts About Parasaurolophus
Here’s what makes this crested dinosaur stand out:
- Name Meaning: Parasaurolophus means “near crested lizard.”
- Time Period: Lived about 76–74 million years ago during the Late Cretaceous.
- Size: Around 31 feet long and weighing up to 3.5 tons.
- Diet: Herbivore, feeding on plants like ferns, conifers, and cycads.
- Habitat: Lush floodplains and forests in what is now North America.
Max’s Encounter: A Dino Symphony
I first spotted a group of Parasaurolophus by a river, their long, curved crests gleaming in the sunlight. The crests were even more impressive up close—like long tubes that arched back over their heads.
I crouched down to get a better angle with my camera, and that’s when it happened. One of them tilted its head back and let out a deep, haunting sound that echoed through the valley. It wasn’t a roar; it was more like a trumpet crossed with a foghorn.
The whole herd froze, then started making the same sound, one after the other. The noise was so loud it felt like it was vibrating in my chest. At first, I thought they’d spotted me, but then I saw what they were warning each other about: a pair of dromaeosaurs stalking them from the trees.
Thankfully, the predators decided the herd was too alert and backed off. Meanwhile, I was still frozen in place, clutching my camera and wondering if my ears would ever stop ringing.
The Crest: Nature’s Trumpet
Parasaurolophus’s long crest wasn’t just for decoration—it was a multitool. Here’s what scientists think it could do:
- Communication
The hollow tubes inside the crest acted like a wind instrument, producing deep, resonating calls. These sounds were likely used for communication, from warning of predators to calling to mates. - Thermoregulation
Some researchers believe the crest may have helped regulate body temperature by acting like a heat exchanger. - Attraction
The size and shape of the crest might have been a way to attract mates, with larger, more elaborate crests signaling stronger individuals.
Did You Know?
- Parasaurolophus was part of the hadrosaur family, also known as duck-billed dinosaurs.
- Each Parasaurolophus species had a slightly different crest shape, which might have produced unique sounds.
- Fossilized skin impressions show they had scaly, pebbled skin similar to modern reptiles.
Real Parasaurolophus Pictures
The photo I took of the Parasaurolophus herd is one of my favorites. You can see the sunlight hitting their crests just right, highlighting the hollow structure. Sam says it looks like a postcard. I say it’s proof that dinosaurs weren’t just giant lizards—they were complex, social animals.

Field Notes From Max
- Survival Tip: Don’t mistake loud for harmless. Parasaurolophus may not have sharp teeth or claws, but their warning calls can draw predators—or scare the life out of you.
- What I Learned: Dinosaurs had social structures and used sound to communicate in ways we’re only beginning to understand.
- Favorite Moment: Watching the herd move together, their calls echoing like a prehistoric symphony.
The Bigger Picture
Parasaurolophus is a perfect example of how dinosaurs weren’t just about survival—they were about connection. Whether they were warning each other of danger or showing off to impress a mate, their crests were more than just tools; they were part of who they were.
Back home, the debate about dinosaur intelligence rages on. Were they smart, or just instinct-driven? My encounter with Parasaurolophus suggests they were a lot more complex than we give them credit for. Of course, Dr. Kline says I’m “anthropomorphizing,” but I think he’s just jealous he’s never heard a dinosaur orchestra.
Sam, as always, had a practical suggestion: “You should sell those pictures to a sound lab or something. ‘Prehistoric Soundscapes, by Max Vale.’ You’d make a fortune!”

Think all predators look the same? Think again. Carnotaurus is like the dino world’s weird cousin, and wait until you hear about the time it almost outsmarted me. Stay tuned!
