Open AccessMesozoic evolution of cicadas and their origins of vocalization and root feeding
Extant cicada (Hemiptera: Cicadoidea) includes widely distributed Cicadidae and relictual Tettigarctidae, with fossils ascribed to these two groups based on several distinct, minimally varying morphological di...

Open AccessA new method for examining the co-occurrence network of fossil assemblages
Currently, studies of ancient faunal community networks have been based mostly on uniformitarian and functional morphological evidence. As an important source of data, taphonomic evidence offers the opportunit...

Open AccessPersistent biotic interactions of a Gondwanan conifer from Cretaceous Patagonia to modern Malesia
Many plant genera in the tropical West Pacific are survivors from the paleo-rainforests of Gondwana. For example, the oldest fossils of the Malesian and Australasian conifer Agathis (Araucariaceae) come from the ...

Open AccessUnlocking the mystery of the mid-Cretaceous Mysteriomorphidae (Coleoptera: Elateroidea) and modalities in transiting from gymnosperms to angiosperms
The monospecific family Mysteriomorphidae was recently described based on two fossil specimens from the Late Cretaceous Kachin amber of northern Myanmar. The family was placed in Elateriformia incertae sedis with...

Open AccessLife habits and evolutionary biology of new two-winged long-proboscid scorpionflies from mid-Cretaceous Myanmar amber
Long-proboscid scorpionflies are enigmatic, mid-Mesozoic insects associated with gymnosperm pollination. One major lineage, Aneuretopsychina, consists of four families plus two haustellate clades, Diptera and ...

The Fossil Record of Insect Mouthparts: Innovation, Functional Convergence, and Associations with Other Organisms
The mouthparts of insects are a phenomenal example of a multi-element, modular, feeding apparatus that repeatedly has been modified structurally to perform every feeding function imaginable in the terrestrial ...

Expansion of Arthropod Herbivory in Late Triassic South Africa: The Molteno Biota, Aasvoëlberg 411 Site and Developmental Biology of a Gall
The Carnian Aasvoëlberg 411 (Aas411) site of the Molteno Formation in South Africa provides exceptional data for understanding how plants, their arthropod herbivores and interactions responded to the P-Tr ecol...

Early bursts of diversification defined the faunal colonization of land
The colonization of land was one of the major events in Earth history, leading to the expansion of life and laying the foundations for the modern biosphere. We examined trace fossils, the record of the activit...

Rapid recovery of Patagonian plant–insect associations after the end-Cretaceous extinction
The Southern Hemisphere may have provided biodiversity refugia after the Cretaceous/Palaeogene (K/Pg) mass extinction. However, few extinction and recovery studies have been conducted in the terrestrial realm ...

Article
Open AccessNew data from the Middle Jurassic of China shed light on the phylogeny and origin of the proboscis in the Mesopsychidae (Insecta: Mecoptera)
The Mesopsychidae is an extinct family of Mecoptera, comprising eleven described genera from Upper Permian to Lower Cretaceous deposits. In 2009, several well-preserved mesopsychids with long proboscides were ...

Chapter
The End-Cretaceous Extinction and Ecosystem Change
Examination of fossil plant–insect associations in the continental realm and trace fossils in the marine realm provide considerable data for understanding organismic response to major ecological crises, such a...

Chapter
The Mesozoic Lacustrine Revolution
The Mesozoic Lacustrine Revolution (MLR) represents a significant evolutionary event for continental ecosystems. Evidence from the ichnologic and body-fossil records yields major insights into the timing and n...

Open AccessLife habits, hox genes, and affinities of a 311 million-year-old holometabolan larva
Holometabolous insects are the most diverse, speciose and ubiquitous group of multicellular organisms in terrestrial and freshwater ecosystems. The enormous evolutionary and ecological success of Holometabola ...

Evolution of a complex behavior: the origin and initial diversification of foliar galling by Permian insects
A central notion of the early evolution of insect galling is that this unique behavior was uncommon to rare before the diversification of angiosperms 135 to 125 m.yr. ago. However, evidence accumulated during ...

Open AccessThe fossil record and taphonomy of butterflies and moths (Insecta, Lepidoptera): implications for evolutionary diversity and divergence-time estimates
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 ...

Open AccessMesozoic lacewings from China provide phylogenetic insight into evolution of the Kalligrammatidae (Neuroptera)
The Kalligrammatidae are distinctive, large, conspicuous, lacewings found in Eurasia from the Middle Jurassic to mid Early Cretaceous. Because of incomplete and often inadequate fossil preservation, an absence...

Deep-time patterns of tissue consumption by terrestrial arthropod herbivores
A survey of the fossil record of land-plant tissues and their damage by arthropods reveals several results that shed light on trophic trends in host-plant resource use by arthropods. All 14 major plant tissues...
