Fossil insects
Background It is conventionally accepted that the lepidopteran fossil record is significantly incomplete when compared to the fossil records of other, very diverse, extant insect orders. Such an assumption, however, has been based on cumulative diversity data rather than using alternative statistical approaches from actual specimen counts. Results …A spider in Baltic amber. The evolution of spiders has been ongoing for at least 380 million years.The group's origins lie within an arachnid sub-group defined by the presence of book lungs (the tretrapulmonates); the arachnids as a whole evolved from aquatic chelicerate ancestors. More than 45,000 extant species have been described, organised …reveal unweathered surfaces. However, the insect fossils are not readily visible; the shale must be wetted and, given the small size of the average Kishenehn Formation insect fossil, examined with a hand lens. The middle sequence of the Coal Creek Member has been estimated to be 46.2 ± 0.4 million years old (early Middle

In this article, we review important findings of fossil insects from the Yanliao Biota and the Jehol Biota to highlight the diverse systematics and early evolution of insects; their …A few fossilized flying insects with wings were found as well as some very tiny spiders and some yet smaller mites. The size of these insect fossils was about 1/10 inch or less. The following photo is what appears to be some type of leaf hopper. This is one of those unusual findings in which the insect, rather than being fossilized, appeared to ... Insect damage on compressed fossil leaves provides abundant information about terrestrial food webs, because the diversity of plants and their insect feeding associations can be directly compared using the same fossils, at high sample sizes and in fine stratigraphic context (5–7).Modern ecological observations generally show positive …
