“…Plants are frequent in thicker layers just above these laminites but absent in the laminites. These traces are similar to the modern grazing trails formed by stratiomyid or ceratopogonid fly larvae in shallow freshwater or brackish sediments ( Metz, 1987 ; Mángano, Buatois & Claps, 1996 ). The oldest known Stratiomyidae and Ceratopogonidae are Lower Cretaceous ( Huang & Lin, 2007 ; Borkent, Coram & Jarzembowski, 2013 ).…”

The Late Kimmeridgian marine limestones of the area around Orbagnoux (Rhône, France) are well known for their fish fauna and terrestrial flora. Here we record the first insects and their activities (mines on leaves and trails in sediments) from these layers, including the oldest record of the gerromorphan bugs, as a new genus and species Gallomesovelia grioti, attributed to the most basal family Mesoveliidae and subfamily Madeoveliinae. These new fossils suggest the presence of a complex terrestrial palaeoecosystem on emerged lands near the lagoon where the limestones were deposited. The exquisite state of preservation of these fossils also suggests that these outcrops can potentially become an important Konservat-Lagerstätte for the Late Jurassic of Western Europe.

“…Fiege (1949) proposed such an environment for an assemblage of simple traces from the Upper Triassic of Germany. Traces in recent pools have been studied by Fiege (1961), Chamberlain (1975), Ratcliffe & Fagerstrom (1980), Metz (1987b), andMángano et al (1996). In recent ponds most of the traces are produced by insects and their larvae.…”

Numerous invertebrate trace fossils and small rare vertebrate tracks are reported and described from the Upper Oligocene deposits of the Lower Freshwater Molasse in eastern Switzerland. They are commonly accompanied by mud-cracks, raindrops, and plant remains, mostly leaves. The invertebrate trace fossils were produced by different animals, mostly insect larvae, nematodes, and probably by molluscs, in desiccating pools on a fluvial plain of a braided river. The trace fossil assemblage differs from the Scoyenia ichnofacies which is typical for terrestrial fluvial plain environment. Instead, it resembles the impoverished Mermia ichnofacies which is probably common but poorly known in this environment. This ichnofacies corresponds to a low energy environment, most probably to fluvial plain ponds. ZUSAMMENFASSUNGAus der oberoligozänen Süsswasser-Molasse der Ostschweiz werden zahlreiche Spurenfossilien von Invertebraten und einige Spuren kleiner Vertebraten beschrieben. Diese Spuren sind häufig mit Trockenrissen, Abdrücken von Regentropfen und Pflanzenresten, vor allem Blättern, assoziiert. Verschiedene Organismen, meist Insektenlarven, Nematoden und möglicherweise Mollusken, haben die Invertebraten-Spuren in austrocknenden Tümpeln auf einer Schwemmlandebene hinterlassen. Die beschriebene Assoziation von Spurenfossilien unterscheidet sich von der Scoyenia Ichnofazies, die für Ablagerungen im Bereich von Schwemmlandebenen typisch ist. Statt dessen gleicht sie einer verarmten Mermia Ichnofazies, die aus diesem Ablagerungsraum wenig bekannt ist, aber wahrscheinlich häufig auftritt. Diese Ichnofazies entspricht einem Ablagerungsraum geringer Energie, wie er in Tümpeln auf einer Flussebene vorkommt.

“…Nematodes, annelids, cyclostomates and fly larvae had been suggested as Cochlichnus tracemaker (Chamberlain, 1975;Buatois & Mángano, 1993;Głuszek, 1995;Gibert et al, 2000;Uchman et al, 2009). However, Diptera are not present in the fossil record before the Upper Triassic (Mángano et al, 1996). Grazing, feeding, locomotion, and predation are the main ethologic behaviors represented by Cochlichnus (Eagar et al, 1985;Dam, 1990;Netto, 1992;Buatois & Mángano, 1993;Głuszek, 1995;Buatois et al, 1997;Sarkar et al, 2009), being recorded in marine, marginal-marine and continental subaquatic environments, including lacustrine (e.g.…”

-The ichnofauna of the Teresina Formation from the Cerro Caveiras (Dom Pedrito, Rio Grande do Sul State, South Brazil) is revised in this paper. Bergaueria isp., Cochlichnus cf. anguineus, Cruziana problematica, cf. Diplocraterion isp., Diplopodichnus biformis, Helminthopsis isp., Lockeia siliquaria, Multina arcuata isp. nov., Oldhamia isp., Palaeophycus striatus, P. tubularis, Phymatoderma burkei, Planolites beverleyensis, P. montanus, Teichichnus isp., and Thalassinoides isp. were recorded. Isopodichnus problematicus, Helminthopsis tenuis and Unarites isp., previously described in these deposits are now described as Cruziana problematica, indeterminate molluscan trail, and Multina arcuata isp. nov., respectively. The ichnofauna is composed chiefly of horizontal, simple shallow burrows, with a predominance of feeding structures. Resting, dwelling and crawling structures also occur, as well as indeterminate tiny grazing trails, but are less frequent. Ichnodiversity and intensity of bioturbation are usually low, and P. montanus is the commonest ichnotaxon. The main characteristics of the ichnofauna suggest a marine benthic fauna stressed by salinity fluctuations and resulting in an impoverished Cruziana ichnofacies. The absence of vertical burrows and the common occurrences of monospecific assemblages of Planolites indicate extreme stress events, probably due to the establishment of freshwater conditions. Further studies focused on the ichnological signatures of these deposits will provide more detailed information to improve the current paleoecologic and paleoenvironmental interpretations of the Teresina Formation deposits.
