Day 30: Not all dinosaurs were ruthless hunters or solitary giants. Some, like Maiasaura, were surprisingly nurturing—caring for their young in ways that might remind you of modern animals. When I stumbled upon a Maiasaura nesting site, I expected to learn more about these fascinating “good mothers.” What I didn’t expect was to find another piece of Captain Harrow’s treasure—and a warning that shook me to my core.
Quick Facts About Maiasaura
Here’s why this herbivorous dinosaur earned the nickname “Good Mother Lizard”:
- Name Meaning: Maiasaura means “good mother lizard,” based on fossil evidence of its nurturing behavior.
- Time Period: Lived around 76–74 million years ago during the Late Cretaceous.
- Size: About 30 feet long and weighing up to 4 tons.
- Diet: Herbivore, feeding on tough plants like cycads, conifers, and ferns.
- Habitat: Open floodplains and forests in North America.
Max’s Encounter: A Nest Full of Surprises
I found the nesting site in a wide, open plain, sheltered by a ring of low hills. Dozens of egg-shaped depressions dotted the ground, each containing fossilized remains of eggshells and tiny bones. Some of the eggs had even started to hatch, with baby Maiasaura poking their heads out into the world.
I crouched low, snapping photos, marveling at how these dinosaurs cared for their young. Adult Maiasaura were scattered around the nesting site, grazing and keeping watch. Their gentle movements reminded me more of elephants than reptiles, and I felt like I was watching history come alive.
Then I spotted something strange. Near one of the nests was a small, weathered object half-buried in the dirt. It was a piece of metal shaped like a locket, engraved with a pirate ship and the words “The Treasure’s Heart.” I reached for it, but before I could grab it, a deep growl froze me in place.
An adult Maiasaura had noticed me. It let out a low, rumbling call, its body tensing as it stepped between me and the nest. I backed away slowly, keeping my hands visible, until it seemed satisfied I wasn’t a threat. Only then did I make a second attempt to grab the locket—and this time, I succeeded.
Captain Harrow’s Treasure Clue #5:
The locket contained a tiny compass that spun wildly when I opened it, pointing in random directions before finally settling on a point to the southwest. Was it leading to the next piece of the treasure, or something else entirely?
What Makes Maiasaura So Unique?
- Parental Care
- Fossils show that Maiasaura cared for their young, feeding hatchlings and protecting their nests from predators.
- Social Behavior
- They likely lived in herds, with adults working together to raise and protect their young.
- Nesting Sites
- Maiasaura nests were carefully arranged in colonies, much like modern birds, showing an advanced level of organization.
Did You Know?
- Maiasaura was the first dinosaur discovered with evidence of parental care, changing how scientists viewed dinosaur behavior.
- Its eggs were about the size of a cantaloupe, and hatchlings were roughly the size of a small cat.
- Hatchlings grew rapidly, suggesting Maiasaura provided food and protection to help them survive.
Real Maiasaura Pictures
The photo I managed to take shows an adult Maiasaura standing guard over its nest, its gentle demeanor masking a fierce protective instinct. Sam said it looked like “a prehistoric daycare with the world’s most overprotective babysitters,” and she’s not wrong.
[Dinosaur pictures are coming soon, just waiting for the film to develop!]
Field Notes From Max
- Survival Tip: Never get between a Maiasaura and its nest. They may be herbivores, but their size and strength make them dangerous when protecting their young.
- What I Learned: Dinosaurs weren’t just cold-blooded reptiles—they had social structures and behaviors that feel surprisingly familiar.
- Favorite Moment: Finding the locket and realizing Harrow’s treasure isn’t just gold—it’s tied to something much bigger.
Modern-Day Fallout: The Clock Is Ticking
Back home, the locket became the center of a heated debate. Sam was convinced the spinning compass meant we were close to finding the treasure, but I wasn’t so sure. “What if it’s not pointing to the treasure?” I said. “What if it’s pointing to something we’re not supposed to find?”
Meanwhile, the FBI agent, Agent Carter, sent another cryptic message. This time, it wasn’t a warning—it was a threat. “Stop now, or there will be consequences,” the text read.
And then there were the aliens. They hadn’t appeared since the Archaeopteryx encounter, but I couldn’t shake the feeling they were watching, waiting for me to make a move. If the locket’s compass was leading to something they didn’t want me to find, what would they do to stop me?
The Bigger Picture
Maiasaura shows us a side of dinosaurs we don’t often see—nurturing, social, and deeply connected to their young. But in the context of my mission, it raises more questions than answers.
The locket’s compass, the growing threats from Agent Carter, and the eerie silence from the aliens are all pointing to something bigger. Whatever Harrow’s treasure is, it’s more than just gold. And with every clue I uncover, the stakes are rising—not just for me, but for the entire timeline.

PS – I think I got some of my field journal dates wrong so I’m going to stop posting until I can figure that out. In the meantime I hope you catch up on my adventures – let me know in the comments if you’re ready to hear what happens next!
