"We've basically been able to show that spore-forming organisms preserved in amber have the ability to be revived," said Robin Steele, president of Ambergene.

The Late Series 3, Stage 4 to Furongian (Upper Cambrian) Orsten fauna includes fossilized organisms preserved in Orsten lagerstätten, notably at Kinnekulle and on the island of Öland, all in Sweden.

The scientific names of taxa are formally attached to a type, which is one particular specimen (or in some cases a group of specimens, or in some cases an illustration) of the organism, preserved in a museum.

It is rare to find organisms preserved by replacement alone (as opposed to in combination with permineralization), but these fossils present significant importance to paleontologists because these fossils tend to be very detailed.

The Small Carbonaceous Fossils (SCFs) are sub-millimetric organic remains of organisms preserved in sedimentary strata.

Phase one of the Darwin Centre houses the Zoological department's 'spirit collections' - organisms preserved in alcohol.

The community of organisms preserved is a good representation of the (preservable) community; the biasing effects of time-averaging and preferential decay seem to be minimal.

Three-dimensional preservation is most common, with organisms preserved in sandy beds containing internal bedding.

The majority of such claims were based on the retrieval of DNA from organisms preserved in amber.
