Watch people hunting fossils for the first time and you'll see the same thing almost every time: they walk. Head down, scanning the shoreline, moving at a steady pace. Looking hard, covering ground.
It feels productive. It mostly isn't.
Teeth don't reveal themselves to the first pass. They reveal themselves to the third or fourth — after your eyes have calibrated to what the spot contains.
The thing about a good fossil shoreline is that it isn't uniformly productive. There's a patch where something's going on — maybe a pocket of darker lag material, maybe where a recent tide left a concentration. And there are long stretches where there's not much to find.
If you walk past the productive patch at speed, you miss it. Scanning at three miles an hour, your brain rejects almost everything it sees. You need to slow down long enough for your eyes to adjust to what the specific patch contains — what the normal background looks like, what the anomalies are.
The Method
Find a patch that looks plausible. Dark material, good waterline exposure, something that looks different from the stretches on either side.
Mentally box off about two meters square. That's your patch.
Crouch or sit down. Dig in. Work it.
Scoop and sift, or just scan with your eyes, turning over anything that catches the light. Don't leave until you've either found something or you're genuinely sure the patch is empty. Fifteen to twenty minutes is not too long.
Then move on. Pick another patch. Repeat.
What Happens When You Slow Down
Your eyes calibrate. The first minute in a patch, everything looks like shell. By minute five, the normal background stops registering and the outliers pop. This is a real perceptual effect, not willpower.
Small finds build the eye for larger ones. Once you've picked up a dozen small teeth, the occasional big one stops surprising you. You're not hoping anymore — you're looking with knowledge of what teeth actually look like in this specific sediment.
You find the hidden ones. Teeth get tucked under shell fragments, half-buried in sand, flipped upside down so the crown is hidden. Moving things around is how you find what's actually there.
You don't chase the shoreline. A productive patch is worth more than a kilometer of indifferent beach. If you've found one, you've probably found the spot — stay.
When to Move On
You've worked the patch thoroughly. You've scooped and sifted the darker material. You've turned things over. Nothing's coming up, or the finds have tapered off.
Move. But move to another plausible patch, not to a different stretch of shoreline. The island rewards depth over distance.
This is, honestly, the difference between a beginner's trip and a veteran's. Not better eyes. Not better luck. Just the discipline to stay put long enough for the patch to give up what it has.
