It’s only just occurred to me that dinosaur bones like this are in soil not rock? Even if it’s not technically soil, the bones are at least buried in something fairly soft.

That’s crazy. I’ve only ever thought of fossils as being encased inside hard rock.

The bias of the fossil record makes a discovery like this so unlikely that it’s objectively joyous when it happens.




Yes, fossils form in sedimentary rock, which is relatively soft rock.
