You’re riding through the Heartlands, minding your own business, when you stumble across a ribcage the size of a stagecoach sticking out of the dirt. It’s weird. It’s ancient. And if you’re trying to hit that 100% completion mark in Red Dead Redemption 2, it’s also your new full-time job. Finding a reliable rdr2 dinosaur bones locations map isn't just about ticking a box; it's about navigating some of the most vertical, frustrating, and easily-missed terrain Rockstar ever designed.
Deborah MacGuiness is the NPC who starts this whole mess. She’s an amateur paleontologist you’ll find in the Heartlands, and she’s convinced she’s on the verge of a breakthrough. She wants 30 bones. Thirty. That sounds easy until you realize some of them are tucked onto cliff faces where a single slip sends Arthur (or John) tumbling to a very crunchy death. This isn't just a "go here, press X" quest. It’s a test of patience.

Why the Search for Bones is Actually Harder Than It Looks
Most people think they can just pull up a map on their phone and breeze through it. They’re wrong. The problem with most rdr2 dinosaur bones locations map resources is that they don't account for the sheer verticality of the game world. You might be standing exactly on the yellow dot, but the bone is actually fifty feet above you on a narrow ridge or hidden inside a cave you didn't see.
Eagle Eye is your best friend here. If you aren't clicking those sticks every five seconds, you're going to walk right past a million-year-old fossil. The bones emit a faint yellow "scent" or glow when Eagle Eye is active, which is often the only way to distinguish a prehistoric femur from a regular old rock.
The New Hanover and Lemoyne Cluster
Start small.
The Heartlands and the surrounding areas hold a decent chunk of the fossils. There’s one right near where you meet Deborah, tucked into a grassy knoll. It’s a "gimme." But things get tricky fast. Take the bone at Oil Derrick, for instance. You actually have to climb down into the dark, murky bottom of a well underneath the rig to find it. It's claustrophobic and easy to skip if you're just scanning the horizon.
Over in Lemoyne, specifically around Scarlett Meadows, you’ll find bones that are practically camouflaged by the red mud. There's one near Dewberry Creek that honestly looks like a piece of driftwood. If you're not paying attention to the way the ground slopes, you'll circle it for twenty minutes.
The Grizzlies: A Parkour Nightmare
This is where the quest gets mean.
The Grizzlies are beautiful, sure, but they’re a nightmare for fossil hunters. There’s a bone located at O'Creagh's Run that requires some serious mountain goat energy to reach. Then there’s the one at "The Loft." You’re not looking for something on the ground here; you’re looking at the rock face itself.
Rockstar loves to hide these things on the edges of precipices. You’ll find yourself whistling for your horse, hoping it doesn't fall off the cliff while you're trying to inspect a fossilized spine. The bone near Mount Shann is particularly notorious. You have to navigate these narrow switchbacks, and if the weather turns—which it always does in the Grizzlies—you’re basically flying blind.
Ambarino and the Snow Problem
Ambarino is quiet. It’s also white. Looking for a pale bone in the snow is a special kind of torture.
The bone at Deadboot Creek is a classic example. You’re freezing, your cores are draining, and you’re squinting at the ground trying to find a texture difference. Most players give up here and go hunt a legendary animal instead. Don't. If you’ve got a solid rdr2 dinosaur bones locations map guide, you’ll know to look for the rock outcroppings that break the snowline. The fossils are usually embedded in those exposed stone faces rather than buried under the powder.
The New Austin Wall: The Post-Game Grind
Here’s the kicker. You cannot finish this quest as Arthur Morgan. Well, not without using some pretty intense glitches that involve a covered wagon and a lot of luck to dodge the invisible sniper in Blackwater.
The final eight bones are in New Austin. This means the quest is fundamentally gated behind the Epilogue. You have to wait until you’re playing as John Marston to head into the desert.
The New Austin bones are, ironically, some of the coolest looking. You’ve got a massive set of ribs in Gaptooth Ridge and a skull in Rio Bravo that looks like something out of a horror movie. The terrain is more open, which makes the rdr2 dinosaur bones locations map easier to follow in these regions, but the heat haze and the sheer distance between them makes it a slog.
Tricky Spots in the Desert
- Jorge's Gap: The bone is on a ridge overlooking the gap. If you’re down in the ravine, you’re in the wrong place.
- Cholla Springs: There’s one tucked into a rock wall that’s almost completely obscured by desert scrub.
- San Luis River: This one is way out on the edge. It feels like you’re riding to the end of the world.
The Rewards: Is It Actually Worth It?
Honestly? It depends on what you value.
Once you find all 30 and mail the coordinates to Deborah, she’ll eventually invite you to her ranch (Firwood Rise) to see the "finished" skeleton. It’s... not what you expect. It’s a weird, chimeric monstrosity that she’s cobbled together incorrectly. It’s a funny bit of historical satire on the "Bone Wars" of the 19th century, where real paleontologists like Marsh and Cope were sabotaging each other.
As for tangible loot:
- 1 Bone: You get a Quartz Plug (used to craft the Bear Claw Talisman).
- 15 Bones: You get a Skull Statue.
- 30 Bones: You get the Deborah MacGuiness Invitation and, eventually, the Deborah MacGuiness Knife.
The knife is the real prize. It’s a unique bone-handled hunting knife that looks incredible in John’s belt. But let's be real: most people do this for the "Best in the West" trophy and that sweet, sweet 100% notification.
Avoiding Common Mistakes
The biggest mistake is ignoring the mail system. You can’t just find the bones; you have to go to a Post Office and mail the coordinates to Deborah. If you find 29 bones but never mail them, you won't trigger the final cutscene. Do it in batches. Find five, hit a Post Office, then keep going.
Another tip: watch your horse. Your horse will get agitated near some of these locations because predators like cougars or wolves frequent the same rocky ridges where bones are found. If your horse starts huffing and pinning its ears back, get your shotgun out before you start looking for fossils.
Mapping Your Route
If you're starting from scratch, don't jump all over the place. Start in the Heartlands, move north into the Grizzlies, swing west into Big Valley, and then save the New Austin desert for the very end.
Actionable Next Steps
- Check Your Progress: Open your "Task" menu to see how many coordinates you've actually mailed. It's easy to lose track.
- Craft the Talisman: Once you mail your first bone, go to a Fence immediately. The Bear Claw Talisman reduces Health Core drain by 10%, which is a massive quality-of-life upgrade.
- Use the Interactive Maps: Don't just rely on static images. Use an interactive map where you can "mark as found" to avoid backtracking to a bone you've already grabbed.
- Bring Potent Snake Oil: You’ll be using Eagle Eye constantly. Keep your Dead Eye/Eagle Eye bar full so you aren't squinting at rocks in the dark.
Finding every spot on the rdr2 dinosaur bones locations map is a grind, no doubt. But it forces you into corners of the map you’d otherwise never see—hidden valleys, high-altitude ridges, and secret desert overlooks. It’s a tour of the frontier that just happens to involve a lot of dead lizards. Get to a Post Office, get your rewards, and finally put this quest to bed.
