Some may regard uncommon modes of a fossil preservation to be:-
1. Carbon replication of cellulosic structures as in U Carboniferous Plants etc. Also Graptolites in Silurian.
2. "Negative" or "Hollowcast" by solution (of calcareous test) in siliceous bed.
3. Substitution replication by solution effect to Pyrite, Hydrated Silica (flint) or other mineral eg Echinoderma in Cretaceous also wood of tree trunks as in Petrified Forest in Az. USA , also of Ammonites etc in Jurassic
4. "Wrapping" in a Geode, usually with 3 above
What else can I help you with?
Which is not a reason for the lack of a fossil record from the precanbrian time?
The fossil records have eroded due to lack of proper preservation.
When tiny spaces inside a fossil are filled in with minerals you have what kind of preservation?
You have what is known as permineralization preservation when tiny spaces inside a fossil are filled in with minerals. This process can result in the fossil being preserved in great detail, often retaining the original structure of the organism.
Which type of fossil preservation's is a thin carbon silhouette of the original organism?
Carbon film
What effect does continental drift have on fossil remains?
Continental drift can affect fossil remains by causing them to be dispersed across different continents as landmasses move. It can also result in changes to the environmental conditions where fossils are found, impacting preservation and fossil formation processes. Additionally, the movement of continents can lead to the creation of new habitats or barriers, influencing the distribution and evolution of species.
How do you define different Ag and Bg phonon modes?
Ag phonon modes refer to acoustic phonon modes where all atoms move in phase, while Bg phonon modes refer to optical phonon modes where atoms move in opposite directions. Ag modes are usually lower in energy and frequency compared to Bg modes. These modes are often used to describe the vibrational behavior of crystals in condensed matter physics.

What do you do with a skull fossil in diamond?
Go underground and dig on walls. its uncommon but you will eventually find it.
What is Conservation Lagerstätten?
(Konservat-Lagerstätten) - fossil deposits where preservation is remarkable because of the unusual quality.
What are the fossils?
There are rarer fossils, as in fossils that belong to creatures that haven't been discovered yet or are very uncommon, but no "best" fossil.
What are the best fossils?
There are rarer fossils, as in fossils that belong to creatures that haven't been discovered yet or are very uncommon, but no "best" fossil.
Is buried slowly a condition that makes fossil formations more likely?
No. Preservation as a fossil is most likely when the organism is buried quickly. Slow burial gives opportunity for decay and other destructive processes to occur.
What is the difference between fossil rocks and non fossil rocks?
fossil rock has to be sedimentary, never igneous nor metamorphic, it contains dead very old plants, creatures any kind..... and that suggests a suitable environment for preservation; quick burial and no air existence also not a very high temperature to keep the shape of the fossil.
Which type of preservation produces a 3-D replica showing the exterior features of an organism?
Which type of preservation produces a 3-D replica, showing the exterior features of an organism?A. Microfossil B. Carbon film C. Trace fossil D. Cast
What type of fossil is a frozen fossil?
A preserved fossil is an organism or Animal that has been PERFECTLY PRESERVED for lots of years, or however old it may be. For example, a wooly mammoth frozen in the ice for millions of years would be known as a preserved fossil.There are 2 different types of fossil preservation- preservation with alteration and without. With alteration also has different types. The type of organism you are looking for depends on the how it was preserved.
What modes of transportation do not use fossil fuels to power the vehicle?
BicyclesYachts and sailboatsSailing shipsGlidersWind surf skisRowing boats, canoes and kayaksSurfboardsSkisSkateboardsElectric cars charged with renewable electricityHydrogen powered vehiclesVehicles running on biodiesel and other biofuels
