Sometimes the original shells, which are now fossils, are still visible.The Solnhofen Limestone or Solnhofen Plattenkalk, formally known as the Altmühltal Formation, is a Jurassic Konservat-Lagerstätte that preserves a rare assemblage of fossilized organisms, including highly detailed imprints of soft bodied organisms such as sea jellies. The most familiar fossils of the Solnhofen Plattenkalk include the early feathered …This layer of limestone does not contain kerogen so the limestone is weakest in the layers that do contain fossils. When you split this layer, its common to immediately expose fossils. This layer usually does not contain specimens detailed enough for scientific study because of damage from splitting but it's a perfect layer for fossil collectors. An alternative is to dissolve the rock in acid. Most fossil shells were composed originally of calcium carbonate, and many are preserved in . limestone, which is the same chemical make-up.

Quaternary fossils from limestone caves bear various diagenetic features due to the complex nature of sedimentary processes.

Pieces of limestone, shale, and sandstone small enough to hold are debris broken off layers of rock exposed at the surface. In Kansas, sediment in sedimentary rocks was first deposited along shorelines or the floors of seas, deltas , or swamps that covered parts of the state off and on for millions of years—up until about 65 million years ago.Many marine invertebrates like shells form fossils in this way. Amber can preserve organisms if they become trapped in tree resin. The resin will eventually harden to form a golden amber that has been shown to preserve fossils up to 100 million years old.
