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.
Advertisement Ernst A. Bottcher. Natural history specimen dealers had an important role in the development of science in the 18th, 19th and early 20th centuries. They supplied the rapidly growing, both in size and number, museums and educational establishments and private collectors whose collections, either in entirety or parts finally entered museums.
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 ...

Firefly from nearly 100 million years ago represents transitional stage in evolution of its species
Chemical analysis of soil fossils generally focuses on their lime content, which determines both their pH and how reactive they will be to dilute acids. Chemical analysis is also useful, usually through solvent extraction to determine key minerals. This analysis can be of some use in determining the structure of a soil fossil, but today X-ray ...
The trackway Protichnites from the Cambrian, Blackberry Hill, central Wisconsin. A trace fossil, also known as an ichnofossil (/ ˈ ɪ k n oʊ f ɒ s ɪ l /; from Greek: ἴχνος ikhnos "trace, track"), is a fossil record of biological activity by lifeforms but not the preserved remains of the organism itself.
