How they know about fossils buried under? Are there instruments to detect fossiles?
In: Technology
There are things like ground penetrating radar or electrical resistivity detectors, but they’re not very useful for most fossils. It’d have to be pretty big bones or a dense bone bed to show up clearly against the background. Much more commonly, fossil bearing rocks erode at the surface and we’ll see lots of small fragments and other geological clues that tell us it’s a good place to dig. Then paleontologists will dig down or back further into hillsides to get to the deposits.
