Here's another one that seems even more obvious.
I'm struggling to think of any way that doesn't represent a heavy object falling into semi-solid layers of sediment, then new layer forming above it. The layer denoted by the arrow seems to have been almost liquid.
One thing that is certain - that object was not pushed up from below.
It's the sort of thing you could easily model using layers of different coloured sand and dropping a marble into it, then adding more layers.
