The common denominator among most deposits of fossil insects and terrestrial plants is the lake environment. Those insects that became preserved were either living in the fossil lake (autochthonous) or carried into it from surrounding habitats by winds, stream currents, or their own flight (allochthonous).
Biofacts can include but are not limited to plants, seeds, pollen, animal bones, insects, fish bones and mollusks. [1] The study of biofacts, alongside other archaeological remains such as artifacts are a key element to understanding how past societies interacted with their surrounding environment and with each other.
The Lepidoptera fossil record encompasses all butterflies and moths that lived before recorded history. The fossil record for Lepidoptera is lacking in comparison to other winged species, and tending not to be as common as some other insects in the habitats that are most conducive to fossilization , such as lakes and ponds, and their juvenile ...
Fossils are often found flattened along the bedding plane of the rocks in which they occur, though may be found in three dimensions when they are infilled by iron pyrite or some other minerals. They vary in shape, but are most commonly wiktionary:dendritic or branching (such as Dictyonema ), sawblade -like, or " tuning fork "-shaped (such as ...
These fossils are aquatic and terrestrial insects, giving insight into the ecology and biology of the area. [6] Ostracods are believed to have fed on algae on the bottom of the lake. Most of the fossil examples of ostracod come from the preserved carapaces, or feeding appendages. Only one species of ostracods has been described so far.

Palynology is also used to date and understand the evolution of many kinds of plants and animals. In paleoclimatology, fossil palynomorphs are studied for their usefulness in understanding ancient Earth history in terms of reconstructing paleoenvironments and paleoclimates. [3] [4]
