Geological origin and formation process
Ammonites have their geological origin in ancient seas that existed between the Devonian Period (some 400 million years ago) and Cretaceous Period (approximately 66 million years ago), where they thrived as widespread marine organisms inhabiting various marine environments across this period.
Ammonites began their existence with their life cycle as cephalopods similar to modern-day squids and octopuses. Ammonites had soft bodies enclosed within a spiral shell; as they expanded, new chambers would be added until eventually one chamber became their main home – at which point organisms lived within its final chamber.
Once an ammonite died, its shell could become fossilized under certain conditions and fossilization processes involve various steps:
Death and Burial: Once an ammonite had died, its remains must be quickly covered with layers of sediment to avoid further decomposition and destruction by physical and biological processes. By doing this, burial protected its shell against being dismantled into smaller parts that could break apart further over time.
Sediment Accumulation: Over time, layers of sediment accumulated on top of a buried ammonite shell. Their weight gradually compressed all underlying sediments including its own shell.
As sediment layers accumulated, ammonite shells experienced permineralization as they became submerged under groundwater. This process involved infiltrating groundwater rich with minerals into their porous aragonite structure; gradually replacing organic material within it with calcium carbonate minerals like calcium carbonate that gradually replaced it to keep their original form intact.
Lithification: Over millions of years, sediment layers and permineralized shell became compacted due to accumulating sediments above. When combined with heat and pressure effects, this led to their transformation into sedimentary rock deposits – creating sedimentary rock.
Exposure and Discovery: Geological processes such as erosion and tectonic activity can bring fossilized ammonite shells closer to Earth’s surface, where weathering and erosion gradually expose them for discovery by paleontologists, collectors and enthusiasts.
Ammonites fossils are extremely valuable and significant because their conditions for fossilization were so rare; thus making their fossilized shells valuable sources of information about Earth history such as paleobiology, paleoecology, geologic time scale as well as ancient marine ecosystems, evolutionary patterns and life on our planet.
Fossilization process and preservation potential
Ammonites fossilization and preservation are a result of geological processes which have been occurring for millions of years. The key steps of the fossilization process, and the factors that affect the preservation potential for ammonite remains are listed below:
- Rapid Burial: In order to become fossilized, the ammonite organisms must be quickly buried following death in order to avoid scavenging and decomposition. This will also prevent physical damage. Rapid burial is possible through a variety of mechanisms, such as the deposition of sediment during storms, underwater land slides, or sinking into the seabed.
- Sediment accumulation: The ammonite’s shell, once buried, is gradually covered with sediment layers over time. The sediment protects the shell by shielding it from biological and physical disturbances.
- Permineralization: Permineralization plays a vital role in the fossilization process. This process involves the infiltration into the shell’s porous structure by groundwater carrying minerals such as silica or calcite. These minerals fill in the spaces left by the organic material, slowly replacing it with the new mineral.
- Compaction and Lithification: As more sediment layers accumulate on top of the ammonite shells, the weight from the sediments above compacts the sediments below. Compaction and heat/pressure combine to form lithification. The sediment is transformed into sedimentary rocks. The ammonite’s shell is embedded in the matrix of rock.
- Diagenesis: Diagenesis is the term used to describe the physical and chemical changes that take place during the lithification. This includes cementation processes, in which minerals fill the spaces and bind the sediment grains together.
The preservation potential of fossil ammonites is affected by a variety of factors.
- Sediment type: The sediment around the ammonite’s shell is crucial to its preservation. Fine-grained deposits, like clay or silt provide the best conditions for fossil preservation because they protect the fragile shell from decay and damage.
- Burial Environment: Ammonites’ preservation potential is affected by the environment where they are buried. Oxygen-depleted conditions, such as those found in deep marine environments or anaerobic soils, are less conducive to degradation and decomposition, which promotes better fossil preservation.
- Ammonite fossils can be preserved by geological processes such as tectonic activity and erosion: Tectonic forces may deform the original rock layers that contain fossils, and erosion may expose them to weathering or destruction. In contrast, a gentle uplift or minimal erosion may help to preserve fossil-bearing layers.
- The more time an ammonite remains buried, and the better it is protected from destructive processes. Fossils that were buried under stable geological conditions for millions of year are more likely well preserved.
Ammonite fossils have a wide range of preservation potential. Some ammonite specimens have been beautifully preserved. Others may have suffered significant damage, dissolution or alteration during the fossilization or other geological events. The rarity and beauty of ammonite specimen that are exceptionally well preserved adds to the scientific and aesthetic value.
