The occurrence of arthropods in amber exclusively from the Cretaceous and Cenozoic is widely regarded to be a result of the production and preservation of large amounts of tree resin beginning ca. 130 million years (Ma) ago. Abundant 230 million-year-old amber from the Late Triassic (Carnian) of northeastern Italy has previously yielded myriad microorganisms, but we report here that it also preserves arthropods some 100 Ma older than the earliest prior records in amber. The Triassic specimens…

Plant-feeding mite diversity in Triassic amber (Acari: Tetrapodili)

TLDR
Further recovery of mites from this Late Triassic amber is reported, supporting the prediction of a diversity of arthropods to be found in this oldest known fossiliferous resin and two new genera and species of the Tetrapodili lineage are described.

Early Miocene amber inclusions from Mexico reveal antiquity of mangrove-associated copepods

TLDR
The first discovery of amber-preserved harpacticoid copepods, represented by ten putative species belonging to five families, based on Early Miocene samples from Chiapas, southeast Mexico are reported, which highlights the antiquity of the specialized harPacticoid fauna living in this habitat.

Sampling the insects of the amber forest

TLDR
A study in PNAS compares the range of insects trapped in modern tree resin in a Madagascar forest with the diversity of insects that live there, which represents a major step in determining the extent to which inclusions in amber represent the diversity and ecology of ancient forest communities.

NEW FOSSIL LABIDOSTOMATIDS (ACARI: LABIDOSTOMATIDAE) FROM EOCENE AMBER AND PRESENCE OF AN APUSTULATE SPECIES IN EUROPE

TLDR
The first finding of Labidostomatidae from Bitterfield (Germany) amber and Rovno (Ukraine) amber is reported, with an indication that the modern distribution of the genus Sellnickiella results from extinctions over large parts of its former range.

Liverworts from Cretaceous amber

The Carnian Pluvial Episode and the first global appearance of amber

Amber (fossil resin) is not common throughout the fossil record, and previously the only globally significant deposits were thought to occur during the Cretaceous, Eocene, Oligocene and Miocene

A tardigrade in Dominican amber

TLDR
It is proposed that the patchy tardigrade fossil record can be explained by the preferential preservation of these microinvertebrates as amber inclusions, coupled with the scarcity of fossiliferous amber deposits before the Cretaceous.

MIDDLE TRIASSIC AMBER ASSOCIATED WITH VOLTZIALEAN CONIFERS FROM THE SOUTHERN ALPS OF ITALY

Amber from the Carnian succession of the Dolomites and Julian Alps (northeastern Italy) represents one of the most ancient and quantitatively substantial Triassic fossil resin records in the world.

How Time Flies for Flies: Diverse Diptera from the Triassic of Virginia and Early Radiation of the Order

TLDR
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.

Identification of Carboniferous (320 Million Years Old) Class Ic Amber

TLDR
It is found that amber from the Carboniferous, dating to more than 300 million years ago, has a similar chemistry to that of amber from angiosperms that evolved about 150 million years later, demonstrating that preconifer gymnosperms evolved the biosynthetic mechanisms to produce complex polyterpenoid resins earlier than previously believed.

A microworld in Triassic amber

TLDR
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.

Oribatid mites and the decomposition of plant tissues in Paleozoic coal-swamp forests

TLDR
Oribatid mites were important arthropod decomposers in Pennsylvanian coal swamps of Euramerica and consumed dead, aerially-derived plant tissues at ground level, as well as root-penetrated tissues substantially within the peat.

Insect outbreaks produce distinctive carbon isotope signatures in defensive resins and fossiliferous ambers

TLDR
It is shown that infestation results in a rapid 13C enrichment of fresh lodgepole pine resins, in a pattern directly comparable with that observed in resins collected from uninfested trees subjected to water stress, and resin isotopic values are shown to track both the progression of infestation and instances of recovery.
