Recent progress in beetle palaeontology has incited us to re‐address the evolutionary
history of the group. The Permian† Tshekardocoleidae had elytra that covered the posterior …

The fossil record allows a unique glimpse into the evolutionary history of organisms living on
Earth today. We discovered a specimen of the stem group ant† Gerontoformica gracilis …

The Triassic was a crucial period for the early evolution and diversification of insects,
including Coleoptera 1–3—the most diverse order of organisms on Earth. The study of …

The Coleoptera provides an excellent example of the value of fossils for understanding the
evolutionary patterns of recent lineages. We reevaluate the morphology of the Early …

Sphaeriusidae is a small family of tiny aquatic beetles in the suborder Myxophaga. In this
study we characterize two new sphaeriusid fossils from the mid-Cretaceous Burmese amber …

As the only direct records of the history of evolution, it is critical to determine the geological
source of biota-bearing fossils. Through the application of synchrotron-radiation micro …

Abstract Sphaeriusidae (Coleoptera: Myxophaga) is a group of shiny, blackish and
hemispherical riparian beetles, known for their miniaturized bodies. They are worldwide in …

The Umenocoleidae is among the most perplexing fossil insect taxa, widespread at lower
and middle latitudes during the Early Cretaceous and probably becoming extinct after the …

The third member of the extinct ommatid genus Paraodontomma is reported from mid-
Cretaceous Burmese amber. Our observation confirms the transverse ridges on elytra as a …

AimsColeoptera is the largest group on the land, with extremely rich species diversity and
morphological diversity, and plays an important role in terrestrial ecosystems and is closely …
