In vol. ii. of his Flora Fossilis Arctica, Professor Oswald Heer has treated of the Fossil Flora of Bear Island, and shown that it belongs to the Lower Carboniferous Formation, of which it forms the lowest beds (named by him the “Ursa” beds), close to the junction with the Devonian. The Yellow Sandstone of Kiltorcan in Ireland, the Grauwacke of the Vosges, and the southern part of the Black Forest, and of St. John in Canada, belong to the same group. In the summer of 1870 two young Swedish naturalists (Wilander and Nathorst) discovered this same formation in the Klaas Billen Bay of the Eisfiord in Spitzbergen, and brought home fine specimens of Lepidodendron Veltheimianum, and Stigmaria ficoides. It has also been found in West Greenland, for Prof. Nordenskiold tells us that the Swedish expedition, which went to Disco in the course of last summer, to fetch the meteorite, weighing 25 tons, which he discovered at Ovifak in that island, has brought home fossil plants of true Carboniferous age.

The Oligocene palaeontological locality on Matrý Hill near Sebuzín in the České středohoří Mts., North Bohemia, belongs to the Děčín Formation and is dated to 30.8-24.7 Ma according to the regional stratigraphy. It has yielded, in addition to insects from the Heteroptera group, a fossil bee Apis petrefacta and palaeobatrachid frogs, also numerous plant remains. Their recovery began in 1996. The plant fossil assemblage consists mostly of leaf impressions, occasionally accompanied by casts or impressions of fruits. Noteworthy are records of a fern Woodwardia muensteriana, conifers Pinus cf. rigios, P. cf. hepios, Calocedrus suleticensis, Tetraclinis salicornioides, Torreya bilinica, cf. Cephalotaxus parvifolia and numerous angiosperms, e.g. Liriodendron haueri, Daphnogene cinnamomifolia, Platanus neptuni, Cercidiphyllum crenatum, Sloanea artocarpites, Ulmus pyramidalis, Celtis pirskenbergensis, Carya fragiliformis, C. quadrangula, Betula brongniartii, B. dryadum, Alnus rhenana, A. cf. kefersteinii, Carpinus grandis, Ostrya atlantidis, Acer crenatifolium, A. cf. palaeosaccharinum, A. integrilobum and Craigia bronnii. Several angiosperm foliage specimens of both monocots and dicots have not yet been identified to a particular genus and species. The fossil plant assemblage at Matrý corresponds to two vegetation types, i.e. a zonal riparian forest and zonal mixed mesophytic forest, as corroborated by the Integrated Plant Record vegetation analysis. The vegetation thrived under a humid climate, characterized by average values of MAT (13.4 °C), WMMT (23.8 °C), CMMT (3.6 °C) and MAP (1,117 mm). The Matry fossil flora is similar in composition to the flora of Žichov from the same Oligocene Děčín Formation in the České středohoří Mts.

AbstractA new fossil flora is described from the Early Cretaceous of the western Portuguese Basin, based on a combined palynological-mesofossil study. The fossil specimens were extracted from samples collected in the Nossa Senhora da Luz opencast clay pit complex near the village of Juncal in the Estremadura region. The plant-bearing sediments belong to the Famalicão Member of the Figueira da Foz Formation, considered late Aptianearly Albian in age. The palynological assemblage is diverse, including 588 spores and pollen grains assigned to 30 genera and 48 species. The palynoflora is dominated by fern spores and conifer pollen. Angiosperm pollen is also present, but subordinate. The mesofossil flora is less diverse, including 175 specimens ascribed to 17 species, and is dominated by angiosperm fruits and seeds. The mesofossil flora also contains conifer seeds and twigs as well as fossils with selaginellaceous affinity. The fossil assemblage indicates a warm and seasonally dry climate for the Nossa Senhora da Luz flora.

The Impact

Leaf-compression fossils with insect feeding traces are unique in providing rich, direct evidence of two levels in a fossil food web. Plant-insect associations dominate terrestrial trophic interactions, emphasizing the need to understand their ecological and evolutionary history. This paper first discusses methods of recognizing insect herbivore damage on fossil leaves and quantifying fossil insect herbivory. By conducting an unbiased insect damage census, damage frequency (percent of leaves with insect feeding damage), percent of leaf surface area removed by insects, and damage diversity (the number of discrete damage morphotypes, or DTs, found on a fossil flora or individual host plant) can all be measured. Three examples of responses of past plant-insect trophic interactions to environmental stresses are examined. In the first case study, late Oligocene fossil floras from Ethiopia document forest response to local perturbation and key characteristics to recognize disturbance in the plant fossil record. The second case study considers the terrestrial ecosystem response to the catastrophic global perturbation at the Cretaceous–Paleogene boundary. In the third case study, the impact of past global warming events—including the Paleocene–Eocene Thermal Maximum—on insect herbivory is discussed. Productive avenues for further research include: insect damage studies conducted outside the North American Cretaceous and Paleogene, actualistic and taphonomic studies of insect herbivory, and tighter collaboration across paleobotany, paleoentomology, botany, and entomology.
