Abstract: Arthropods and plants play an essential role in terrestrial ecosystems, as they provided the basic organic constituents with extended evolutionary histories and ecological structures (Labandeira, 2006a). Since the earliest terrestrialisation in the latest Silurian/Early Devonian, plant-arthropod associations have been documented in the fossil record (e.g.

Silicified wood remains, especially redeposited driftwood, are relatively abundant in the Central Paratethys upper Oligocene (Egerian) to lower Miocene (Eggenburgian) fluviatile St. Marein-Freischling Formation (SMFF) in northwestern Lower Austria (Waldviertel), especially in the Horn Basin. The SMFF is superimposed on the crystalline units of the Bohemian Massif and in the Horn Basin overlain by marine formations of the lower Miocene (Eggenburgian). Several pieces of silicified wood show flight holes, tunnels (= domichnia) and feeding traces of the new ichnofossil Polyphagichnium altenburgense igen. & isp. nov. which is described in detail herein. The cross-sections of shafts (“flight holes”) and tunnels, which are clearly visible on the surfaces of tangential sections and radial sections of several specimens, are compared with structures of different recent gnawing beetles (suborder Polyphaga). The silicified wood remains are mostly semi-ringporous hardwoods of the fossil group around Quercoxylon furwaldense Gros 1983.

Ovipositor and mouthparts in a fossil insect support a novel ecological role for early orthopterans in 300 million years old forests

A high portion of the earliest known insect fauna is composed of the so-called ‘lobeattid insects’, whose systematic affinities and role as foliage feeders remain debated. We investigated hundreds of samples of a new lobeattid species from the Xiaheyan locality using a combination of photographic techniques, including reflectance transforming imaging, geometric morphometrics, and biomechanics to document its morphology, and infer its phylogenetic position and ecological role. Ctenoptilus frequens sp. nov. possessed a sword-shaped ovipositor with valves interlocked by two ball-and-socket mechanisms, lacked jumping hind-legs, and certain wing venation features. This combination of characters unambiguously supports lobeattids as stem relatives of all living Orthoptera (crickets, grasshoppers, katydids). Given the herein presented and other remains, it follows that this group experienced an early diversification and, additionally, occurred in high individual numbers. The ovipositor shape indicates that ground was the preferred substrate for eggs. Visible mouthparts made it possible to assess the efficiency of the mandibular food uptake system in comparison to a wide array of extant species. The new species was likely omnivorous which explains the paucity of external damage on contemporaneous plant foliage.
