Its record can be traced in the litho- and biostratigraphy of uppermost Eifelian-lowermost Givetian strata and with multiple geochemical and geophysical proxies. In southwest Iberia, within southwestern Ossa-Morena Zone domains, there are rare, scattered Early-Middle Devonian limestone occurrences. One of these occurrences\u2014the Odivelas Limestone type locality\u2014is revisited in terms of conodont biostratigraphy and palynology and the results compared with previous data on reef macrofauna and magnetic susceptibility stratigraphy. The new data show that this locality is probably within the <em class=\"EmphasisTypeItalic \">Polygnathus hemiansatus<\/em> zone, i.e. of the earliest Givetian age. The palynological content of a ca. 2\u00a0m of black, organic-rich, fine grained limestone section is dominated, in varied proportions, by amorphous organic matter, putative fungal hyphae, and prasinophycean algae. The results are interpreted as an indication of high organic productivity and deposition in hypoxic to anoxic settings and probable biotic crisis, in both marine and terrestrial realms, connected with the Middle Devonian Ka\u010d\u00e1k Event. The similarity of this record with other Devonian events is discussed.<\/span><\/p>\n<p><span style=\"font-family: arial, helvetica, sans-serif;\">Read the full article <a href=\"https:\/\/link.springer.com\/article\/10.1007\/s12549-019-00415-1\">here<\/a>.<\/span><\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Gil\u00a0Machado, Ladislav\u00a0Slav\u00edk, Noel\u00a0Moreira, Paulo\u00a0Emanuel\u00a0Fonseca Prasinophyte bloom and putative fungi abundance near the Ka\u010d\u00e1k event (Middle Devonian) from the Odivelas Limestone, Southwest Iberia The Ka\u010d\u00e1k Event is one of the several prominent Devonian climatic and biotic perturbations with a supra-regional to global extent.
