What else can I help you with?
Molds filled with sediments sometimes produce?
Molds and casts may be produced when sediments fill molds left by decayed organisms.
How do fossils form in 5 ways?
Freezing, Amber, Tar seeps, Casts and molds Petrification
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.
Preserved animal tracks are called?
Preserved animal tracks are called trace.
What is something that is not preserved?
Fresh fruits and vegetables are not preserved as they are perishable items that deteriorate quickly without preservation methods like canning or freezing.
Molds filled with sediments sometimes produce?
Molds and casts may be produced when sediments fill molds left by decayed organisms.
What type of fossil is a nest?
molds or casts
What does the presence of seashell molds and casts on mountaintops tell you about the surface of the earth?

Molds casts coprolites and petrified wood are all example of what?
Fossils!!
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.
Which of the major types of fossils does not form in sediments describe how this can form?
Well there are 3 types of fossils: Petrified Fossils, Molds and Cast, and Preserved Remains. Petrified Fossils are the organisms buried in the layers of sediment. Molds and Casts are the organisms, like shells, buried by sediments, in which they gradually dissolve. Preserved Remains are the organisms preserved in other substances. For example, entire organisms, such as huge elephant-like mammoths that lived thousands of years ago, have been preserved in ice. Therefore, Preserved Remains is a major type of fossil that does not form in sediments. This can be formed by decades of being stuck in the ice age and eventually falling through the ice and never getting out. Since you cant get out you get frozen! Being frozen and preserved in another type of substance in called... Preserved Remains! --Hope this could help. Thanks for reading.:)
What are four ways that organisms can be fossilized?
imprints gastroliths coproliths molds
Why Are molds and casts fossils so common?
The real bones are so old that they decay before paleontologists can dig them up.

Why is there a gap of time between the evolution of algae and trilobites?
There isn't, of course, a gap in time. There are, however, very few fossils intermediate between simple stromatolites (the first more or less multicellular organisms) and the first complex organisms found just before the Cambrian Explosion. This gap most likely exists because while predation already existed (organisms consuming other organisms), no organisms had yet developed an internal or external skeleton that could have been preserved at death. The very few organisms from that era that were preserved despite of this, were preserved in the form of molds and casts.
