Insect fossil.
The radiations of terrestrial plants and vertebrates during this period have been widely investigated; however, the Triassic history of insects, the most diverse group of organisms on Earth, remains enigmatic because of the rarity of Early-Middle Triassic fossils. We report new insect fossils from a Ladinian deposit (Tongchuan entomofauna ...
Insect Fossils. Prehistoric insects are various groups of insects that lived before recorded history. Their study is the field of paleoentomology.

Dipterans, aphids and hymenopterans are the most common forms here, the most diverse taxa are …Exactly how insects evolved flight is a heated issue, in part because the fossil evidence for winged insects remains full of gaps. But living insects that are similar to ancestral species could also shed light on the origins of insect flight. In a study reported online this week in Biology Letters, researchers report that bristletails, primitive, wingless …Fossil plants occur much more evenly through time and space, including many important intervals and regions that lack any significant quantity of insect body-fossils. Even when insect fossils are present in the same deposits as plants, both are dispersed and extremely infrequently found in direct trophic association (Nishida & …

Many extant Phasmatodea have either reduced wings or lost them outright, although likewise, many notable exceptions do exist ...Plant-insect interactions are among the most common biotic relationships, both in diversity and abundance. The fossil record reflects these associations as damage traces on the leaves, stems or seeds, allowing researchers to identify the type of interaction and infer about its insect producer.
