Preserved bones and tracks are two types of fossils. Describe three other types of fossils?
Three other types of fossils include molds, casts, and amber fossils. Molds are formed when an organism leaves an impression in sediment, creating a hollow shape. Casts occur when that mold is filled with minerals or sediment, resulting in a replica of the original organism. Amber fossils are created when small organisms, like insects, are trapped in tree resin that hardens over time, preserving them in remarkable detail.
What are Two most common types of fossils?
There are a variety of types of fossils. These include cast fossils, mold fossils, petrified wood, as well as fossil fuels.
How is a cast fossil different from a mold fossil?
if the original organism dissolves or decays, leaving a hollow in the rock, that is a mold. If the mold fills up with sediment which gradually hardens into the shape of the original organism, then that is a cast. Casts are copies of fossilized plants or animals. Molds are hollow impressions of the fossil.

When is a casting disinfected?
A casting in dentistry is disinfected before and after a person trys-in. The casts must be disinfected as they are how molds are created for people's teeth.
Molds filled with sediments sometimes produce?
Molds and casts may be produced when sediments fill molds left by decayed organisms.
How is chocolate shaped?
