Voids left behind by once present fossils are called 'trace fossils'.
No, a fossil formed when an organism buried in sediment dissolves is called a mold fossil. It is created when the organic material of the organism dissolves, leaving behind an impression or cavity in the sediment that hardens into rock.
A mold fossil is formed when an organism dissolves and leaves an empty space in a rock. This empty space can later be filled by other minerals, forming a cast fossil.
Fossils formed when silica is added are called silicified fossils. Silica replaces the original organic material of the organism, resulting in a preserved fossil with a glassy appearance. This process can produce detailed and well-preserved fossils.

Fossils are formed in rocks when the hard body parts of an organism get buried in sediment and are preserved when it turns to rock.
A cast fossil is formed when sand containing an imprint of a plant or animal is buried by sediment and solidifies into rock. The original organism decomposes or is washed away, leaving behind an impression that is filled in with minerals, creating a replica of the organism.
Trace fossils are formed when an organism leaves a trace; such as a footprint, a bite mark, or even poo.
Permineralized fossil are formed when dissolved minerals precipitate from a solution in the space occupied by the organism's remains.
