Carnian-aged amber (c. 230 Ma) from north-eastern Italy contains the first pre-Cretaceous inclusions of arthropods, plant remains and microorganisms. Here, we report further recovery of mites from this Late Triassic amber, supporting the prediction of a diversity of arthropods to be found in this oldest known fossiliferous resin. Two new genera and species of the Tetrapodili lineage, Minyacarus aderces and Cheirolepidoptus dolomiticus, are described. They indicate, along with the two previously… 

Expansion of Arthropod Herbivory in Late Triassic South Africa: The Molteno Biota, Aasvoëlberg 411 Site and Developmental Biology of a Gall

The Carnian Aasvoelberg 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

Two Eocene species of peacock mites (Acari: Tetranychoidea: Tuckerellidae)

Tarsal setations of the two fossils and comparison with those of the recent Tuckerellidae advances discussion on the evolutionary significance of setal variation in acariform mites.

Floral Assemblages and Patterns of Insect Herbivory during the Permian to Triassic of Northeastern Italy

Generalized-to-specialized ratios show minimal change through the interval, although herbivore component community structure (herbivore species feeding on a single plant-host species) increasingly was partitioned from Wuchiapingian to Ladinian.

Insect and mite galls on land plants have a spotty but periodically rich and abundant fossil record of damage types (DTs), ichnotaxa, and informally described gall morphotypes. The earliest gall is

Adaptive Radiation of Four-Legged Mites of the Family Phytoptidae (Acariformes, Eriophyoidea) on Dicotyledons: Host–Parasite Relationships and Ability to Induce Gallogenesis

Analysis of the quantitative traits has shown that no groups of phytoptid species associated with eudicots can be outlined based on the currently available morphometric characters, and the correlation between the prodorsal shield ornamentation, the presence of the tibial solenidion, and their geographic distribution is analyzed.

Molecular phylogeny of the phytoparasitic mite family Phytoptidae (Acariformes: Eriophyoidea) identified the female genitalic anatomy as a major macroevolutionary factor and revealed multiple origins of gall induction

It is shown that gall-inducing ability evolved multiple times in phytoptids, a conclusion contrasting with the general expectation that host characteristics should be a major macroevolutionary force influencing the evolution of host-specific symbionts.

Molecular phylogenetic analyses reveal a deep dichotomy in the conifer-inhabiting genus Trisetacus (Eriophyoidea: Nalepellidae), with the two lineages differing in their female genital morphology and host associations

Six basic types of the female internal genitalia of Trisetacus are identified based on shapes of the spermatheca and sperMathecal tube, suggesting that the female genital morphology is both evolutionarily conserved and is a factor influencing macroevolutionary patterns in this group of mites.

Basal divergence of Eriophyoidea (Acariformes, Eupodina) inferred from combined partial COI and 28S gene sequences and CLSM genital anatomy

The results of this study suggest that the superfamily Eriophyoidea comprises basal paraphyletic pentasetacines (Loboquintus and Pentasetacus), and two large monophyletic groups: Eriophyidae s.l.str.



Arthropods in amber from the Triassic Period

It is found that the abundance of amber during the Carnian is globally anomalous for the pre-Cretaceous and may, alternatively, be related to paleoclimate.

Late Triassic Plants from the Julian Alps (Italy)

Abundant and well-preserved plant macrofossils have been recently collected near Dogna in the Julian Alps (Northeastern Italy). The macroflora is borne by a thick succession of subtidal clays, marls

The four phases of plant-arthropod associations in deep time

These four associational phases may be linked to the paleoclimatologic variables of greenhouse/icehouse cycles and atmospheric O2 and CO2 levels by uncertain causes, although some relationship probably is present.

Description of a new relict eriophyoid mite, Loboquintus subsquamatusn. gen. & n. sp. (Eriophyoidea, Phytoptidae, Pentasetacini) based on confocal microscopy, SEM, COI barcoding and novel CLSM anatomy of internal genitalia

A new pentasetacine mite Loboquintus subsquamatus was found living under scale-like leaves of 2–3 years old twigs of Cupressus sempervirens in Montenegro and possesses a number of morphological features which clearly distinguish it from all other known eriophyoids.

The fossil mite family Archaeorchestidae (Acari, Oribatida) I: redescription of Strieremaeus illibatus and synonymy of Strieremaeus with Archaeorchestes

A new diagnosis of Strieremaeus is presented, and the Cretaceous fossil genus Archaeorchestes is considered a junior subjective synonym, based on examination of the holotype of the type-species, A. minguezae Arillo & Subias, 2000.

Distribution of living Cupressaceae reflects the breakup of Pangea

It is shown that phylogenetic relationships in the gymnosperm family Cupressaceae (162 species, 32 genera) exhibit patterns expected from the Jurassic/Cretaceous breakup of Pangea, and originated during the Triassic.

Evidence that fossil araucarian cones may have produced seeds with hypogeal germination is discussed in light of recent work on germination of extant bunya seedlings and the discovery of new fossil shoots from the Jurassic Morrison Formation of Utah.

The origin of herbivory on land: Initial patterns of plant tissue consumption by arthropods

The early fossil record of terrestrial arthropod herbivory consists of two pulses, which provide a context for three emerging questions, and provides primary ecological data that remain unaddressed by the body‐fossil record alone.

A microworld in Triassic amber

220-million-year-old droplets of amber containing bacteria, fungi, algae and protozoans that are assignable to extant genera provide insight into the evolution and palaeoecology of Lower Mesozoic microorganisms.
