Fossil insects.

Sep 20, 2023 · The evolution of colour patterning in insects, however, remains poorly understood. Monochromatic colour patterns are evident in fossil insects, especially compression fossils, from many Mesozoic and Palaeozoic localities from the Late Carboniferous onwards [6–8]. However, the insect fauna of the Coal Creek Member is not particularly diverse. Diptera (flies) make up 55 percent of all fossil insects in the collec-tion; of these, more than 80 percent are chironomids (non-biting midges) and representatives of other closely related families. An addi-tional 15 percent of all the fossil insectsInsects were probably similarly abundant in the past, but the fossil record of insects is limited, with only about 7,000 species known. The scarcity of insect fossils (compared to their present, and probable past, diversity) is a consequence of their relative fragility, lack of hard parts, and the fact that they lived on land. The oldest confirmed insect fossil is that of a wingless, silverfish-like creature that lived about 385 million years ago. It’s not until about 60 million years later, during a period of the Earth’s history known as the Pennsylvanian, that insect fossils become abundant.

Acoustic communication is well-known in insects since the Mesozoic, but earlier evidence of this behavior is rare. ... New fossil insect wings (Protohemiptera, family Mesotitanidae). Rec. Aust ...Its sedimentary rock deposits, formed beneath ancient lakes from nearly 16 million years ago, have yielded quite a few fascinating fossil insect specimens. Among these is a now-extinct species of prehistoric honey bee — one whose size rivals that of the modern-day giant honey bee found throughout southern Asia (via Featured Creatures ).

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 …

The fossil insect described in this paper was collected in I958 in the precordilleran region of Mendoza in Argentina by the joint ex-pedition of the Museum of Comparative Zoology and the Museo Argentino de Ciencias Naturales of BuenosAires.

However, cases of mating individuals are particularly rare in the fossil record of insects, and most of them involved preservation in amber while only in rare cases found in compression fossils. This considerably limits our knowledge of mating position and genitalia orientation during the Mesozoic, and hinders our ...

During the past 20 years, more than 1,600 species of well-preserved fossil insects, including members of over 270 families within 24 orders, have been described from the Middle Jurassic Yanliao Entomofauna and Early Cretaceous Jehol Entomofauna in Northeastern China. Diversified fossil insects not only document the origin, systematics, and early evolution of many lineages, but also reveal ...Fossils hold the evidence. Scientists know that dragonflies with wing spans as wide as a hawk’s and cockroaches big enough to take on house cats lived during the Paleozoic era (245-570 million years ago). At the same time, mammoth millipedes longer than a human leg skittered across prehistoric soil.Many fossil insects show monochromatic colour patterns that may provide valuable insights into ancient insect behaviour and ecology. Whether these patterns reflect original pigmentary coloration is, however, unknown, and their formation mechanism has not been investigated.One of the hallmarks of angiosperms is their relationship with animal pollinators, especially insects. As with plants, the diversification of insects is a field with many uncertainties. The origin of several important orders of flower-visiting insects (e.g., Coleoptera, Diptera, Hymenoptera, and Lepidoptera) lies in the Permian or Triassic (300 ...Fossils resembling modern cockroaches are known from rocks as old as the Carboniferous period (320 million years ago), when they dominated insect communities.
