rapid burial and possession of hard parts.
The fossils belong to Petrifaction type of preservation.
The best preservation and fossilization of fossils occurs in calm,aquatic environment.Exceptional preservation also occurs in fine-grained sediments in absence of oxygen.Both this environmental conditions allow easier formation of impression of trapped fossil plant of animal.Impression mainly form from fossils plants and animals that are later decomposed leaving their image shape on the country rock at the time.CONDITIONSWet conditionfine grained country rockaerobic condition that favor decomposition of the fossils leaving behind impression
a type of preservation of food
The preserved remains of animals of evidence of their existence are Fossils Fosssils that provide evidence about the past are called trace fossils.

No, shale is a finer-grained rock and will give better preservation than a sandstone.
According to experts, the best environments to search for fossils are places near rocks or deserts. Most fossils are preserved in these areas.

molds and casts, trace fossils, petrified wood, and carbon filmThe four types of fossils are mold fossils, cast fossils, true-form fossils, and trace fossils. Mold fossils are impressions from when the plant or animal first decomposed. Cast fossils are plant or animal remains. True-form fossils are remaining body parts from an animal. Trace fossils are marks that have been left by animal, such as footprints.
