RE: Paleocene dinosaurs (Ref.s)

"Reworking" refers to material (like fossils) which was already buried in sediment, was then excavated by erosion, and subsequently redeposited in new sediment.

 

Given that stream systems are natural agents of both erosion (on the "outside" of the curve of the meander) and deposition (on the "inside" of the curve of the meander), reworking is not an incredibly uncommon event.

Greetings,
Could someone explain exactly what "reworking" means? It's always confused me.
