Abstract Holometabolan insects, including beetles (Coleoptera), represent about half of all living organisms. Their development cycle, allowing larvae and adults to exploit distinct ecological niches, is traditionally advocated as a critical adaptation resulting in this extraordinary diversity. Herein I report the occurrence of a beetle from the Pennsylvanian deposit of Mazon Creek (IL, USA). It predates the diversification of Coleoptera by at least 65 million years. This identification…

Coleoptera (beetles) is the most species-rich metazoan order, with approximately 380 000 species. To understand how they came to be such a diverse group, we compile a database of global fossil beetle
Late Permian wood-borings reveal an intricate network of ecological relationships
A late Permian fossil wood-boring beetle microcosm is described, with the oldest known example of complex tunnel geometry, host tissue response, and the presence of fungi within.
Evolutionary history of Coleoptera revealed by extensive sampling of genes and species
A time-calibrated phylogeny for Coleoptera is infer based on 95 protein-coding genes in 373 beetle species and an association between the hyperdiversification of beetles and the rise of angiosperms is suggested.
At last, a Pennsylvanian stem-stonefly (Plecoptera) discovered
Continuing efforts on the systematics of Pennsylvanian winged insects indicate a fauna more diverse than previously appreciated, which suggests that insects already had a long, yet undocumented, history by this time.
Leehermania prorova, the Earliest Staphyliniform Beetle, from the Late Triassic of Virginia (Coleoptera: Staphylinidae)
Leehermania prorova Chatzimanolis, Grimaldi, and Engel, new genus and species, is described, which is the earliest staphylinid and the oldest definitive polyphagan beetle.
The evolution and genomic basis of beetle diversity
Beetles diversity appears to have resulted from multiple factors, including low extinction rates over a long evolutionary history, codiversification with angiosperms, and adaptive radiations of specialized herbivorous beetles following convergent horizontal transfers of microbial genes encoding PCWDEs.
Evidence for an Earliest Late Carboniferous Divergence Time and the Early Larval Ecology and Diversification of Major Holometabola Lineages
The divergence date between the Holometabola and its sister clade has been set earlier than previously thought on the basis of fossils or molecular phylogenetic evidence, and this new date provides a minimal calibration date pegged to the Early Carboniferous–Late carboniferous boundary, and approximates an absolute date of 318 million years.
Diversification in the Hexapoda : a molecular phylogenetic perspective
This thesis supports some hypotheses regarding controls on insect richness, whilst conflicting with other, well established ideas, and provides a novel dated phylogenetic framework for further studies of hexapod evolution and identifies several novel directions for research into the origins and development of this diverse and important radiation.

The appearance of such advanced beetles as early as the Lower Anisian suggests that the famous Permian–Triassic crisis was not as deep as it is usually believed, and many beetles survived it, disappearing, however, from the fossil record in the Early Triassic.

It is shown that before the demise of Pennsylvanian age coal-swamp forests, a highly stereotyped life cycle was already established between an insect that was consuming internal plant tissue and a vascular plant host responding to that herbivory.
"Inordinate Fondness" explained: why are there So many beetles?

Repeated origins of angiosperm-feeding beetle lineages are associated with enhanced rates of beetle diversification, indicating a series of adaptive radiations.
Insect origination and extinction in the Phanerozoic
Abstract Insects (Superclass Hexapoda) are the most successful group of living terrestrial arthropods and the richness of their fossil record is only just beginning to be realized with the recent
The earliest holometabolous insect from the Carboniferous: a “crucial” innovation with delayed success (Insecta Protomeropina Protomeropidae)
Abstract Insects dominate Earth by their diversity, and the most are Holometabola. Therefore, the holometabolous development characterised by a pupal stage between larvae and adult seems to be linked
Advances and problems in insect phylogeny
The insects were one of the first groups whose relationships were investigated using the theory and methods of phylogenetic systematics and the cladogram shows numerous doubtful or weakly supported sister group relationships.
Reassigned and new basal Archaeorthoptera from the Upper Carboniferous of Mazon Creek (IL, USA)
O Ongoing reviews of North American and European Upper Carboniferous insect faunas might reveal more similarities than expected in their respective composition, although at a suprageneric taxonomic level.
How Time Flies for Flies: Diverse Diptera from the Triassic of Virginia and Early Radiation of the Order
Flies did not reach modern levels of ecological abundance until the mid-Jurassic, apparently due to diversification within most infraorders by that time, and is described from the Late Carnian of Virginia, USA.
Protophasma dumasii Brongniart 1879, a link between Orthoptera and the ‘dictyopterid’ orders?
Protophasma dumasii is a good candidate to be the absolute out-group for the future phylogenetic analysis of the Archaeorthoptera.
Review of the extinct family Syntonopteridae (order uncertain)
The family Syntonopteridae was named by Handlirsch in 1911 for a new genus and species, Syntonoptera schucherti, from the Upper Carboniferous of Mazon Creek, Illinois. Although the unique specimen on
Early animal evolution: emerging views from comparative biology and geology.
The Cambrian appearance of fossils representing diverse phyla has long inspired hypotheses about possible genetic or environmental catalysts of early animal evolution. Only recently, however, have
