“…Arthropods and other invertebrates, small reptiles, feathers, mammal hairs, plants, and various microbes from different habitats in and close to the amber forests are commonly preserved (1)(2)(3)(4)(5)(6). Ambers and other fossil tree resins are found in hundreds of Old and New World localities (7), with particular abundance in the Cretaceous and the Eocene to Miocene.…”

Amber is of great paleontological importance because it preserves a diverse array of organisms and associated remains from different habitats in and close to the amber-producing forests. Therefore, the discovery of amber inclusions is important not only for tracing the evolutionary history of lineages with otherwise poor fossil records, but also for elucidating the composition, diversity, and ecology of terrestrial paleoecosystems. Here, we report a unique find of African amber with inclusions, from the Cretaceous of Ethiopia. Ancient arthropods belonging to the ants, wasps, thrips, zorapterans, and spiders are the earliest African records of these ecologically important groups and constitute significant discoveries providing insight into the temporal and geographical origins of these lineages. Together with diverse microscopic inclusions, these findings reveal the interactions of plants, fungi and arthropods during an epoch of major change in terrestrial ecosystems, which was caused by the initial radiation of the angiosperms. Because of its age, paleogeographic location and the exceptional preservation of the inclusions, this fossil resin broadens our understanding of the ecology of Cretaceous woodlands.Arachnida | Ethiopia | Hexapoda | microorganisms | paleoecology

“…The present study extends the stratigraphic range of the Rutilariaceae back to the upper Campanian (Late Cretaceous, before 70.5 myr ago) and unpublished observations by one of us (J.W.) indicate the presence of Rutilaria already in the lower Campanian (slightly less than 83.5 myr ago); the data of Girard et al (2009) suggest a considerably longer record for this group (100 myr ago). The earliest putative cymatosirids, e.g.…”

“…Some confusion in the literature (e.g. Olney et al, 2005;Gebeshuber & Crawford, 2006;Girard et al, 2009) is caused by references to Syndetocystis (Greville, 1866) and Syndetoneis (Grunow, 1888), which, although initially regarded as separate genera, were shown to be synonyms of Rutilaria by Ross (1995; see also Ross & Sims, 1974).…”

We present four genera of bipolar centric diatoms with linking structures located on the valve face: Rutilaria (including two new species from the Cretaceous), Spinivinculum, Pseudorutilaria and Kisseleviella, which are commonly classified in the family Rutilariaceae. Functional comparison of their linking structures and modes of chain formation shows considerable diversity and does not support a close phylogenetic relationship among them. In order to reflect the probable phylogeny of this group, the Rutilariaceae is retained as a monotypic family, while Kisseleviella is transferred to the Cymatosiraceae. Rymariopsis gen. nov. is proposed as a possible link between the Hemiaulaceae and the Rutilariaceae. Based on the comparison of the stratigraphic ranges of these taxa with other diatoms, we explore the possibility of a close phylogenetic relationship between bipolar centric diatoms with centrally located linking structures and pennate diatoms, as suggested by recent molecular phylogenies. As a consequence, the Rutilariaceae is suggested as a possible sister taxon of the pennate diatoms.

“…Fossiliferous nodules are present as far back as the middle Cambrian (e.g., Won and Below 1999 ). Amber is also known as Lagerstätte, which confi nes arthropods and plant fragments on land and preserves marine protists in some exceptional cases (Girard et al 2008 ). Although the oldest amber is found from the Upper Carboniferous (Pennsylvanian) Tradewater Formation, Illinois (Bray and Anderson 2009 ), amber becomes common since the Late Cretaceous in relation to the evolutionary history of land plants.…”

The oldest marine protist fossil goes back 1.8 Ga (Statherian, Paleoproterozoic), and the oldest dinosterane biomarkers 1.6 Ga (Calymmian, Mesoproterozoic). The probable heterotrophic agglutinated microfossil appeared when marine metazoans appeared in the Ediacaran. Multichambered foraminifers appeared around the start of biomineralization in Small Shelly Fossils in the early Cambrian. The fi rst fossilizable radiolarian polycystine is likely to have appeared in the period of the Cambrian Explosion. After the initial appearance period, the emergence of fossilizable skeleton formative ability was concentrated in fi ve short geological time intervals: (1) the Middle to Late Devonian for calcareous benthic foraminifers; (2) the Carnian to the Rhaetian (Triassic) for the "switching on" of fossilizable dinofl agellate cysts, nannoliths, coccoliths and calcareous cysts, and probably the molecular appearance of diatoms; (3) the Toarcian-Aalenian Ages for diversifi ed dinofl agellates and coccolithophores, the establishment of symbiosis in radiolarian Acantharia and the appearance of planktic lifestyle in foraminifers; (4) the Albian-Maastrichtian Ages for the rapid accumulation of coccolithophores, the start of skeletogenesis both in silicofl agellates and marine centric diatoms, molecular appearance of both araphid and raphid diatoms, and the appearance of fossilizable araphid diatoms; and (5) the middle to late Eocene for the appearance of fossilizable raphid diatoms and radiolarian colonial collodarians and the continuous occurrences of ebridians. The establishment of the modern-type marine protist world was concluded in the late Eocene by the appearance of collodarians, the continuous occurrences of ebridians, and the substituted silicon precipitation marine protists as diatoms.
