Resumen:
Palynomorphs, including pollen, plant spores, and dinoflagellates are widely used as biological, paleoecological, and paleoclimatological proxies that provide a regional-scale signal. Within the spectrum of organismal remains classified as “palynomorphs” in the deep-time fossil record, fungi provide a unique opportunity to elucidate a local, rather than regional signal. Historically, paleoecological and paleoclimatological interpretations using fossil fungi have been hampered by datasets which relied on fossil names, many of which were derived from Sarccado spore morphologies and had no relation to extant taxa. The Fungi in a Warmer World (FiaWW) project has developed an identification method based on the system used by mycologists for morphological comparisons to equate defined fossil taxa with their nearest living relatives and to identify previously unidentified fossil taxa as members of extant fungal clades. This permits the delineation of ecological requirements and paleobiogeographic distribution patterns for fungal assemblages and functional guilds in the fossil record, which can then be used to describe paleoecological conditions and paleoclimates present at the time of deposition. Here we present initial results from multiple depositional settings across the Miocene of Europe, SE Asia, and the United States to demonstrate the utility of fossil fungi as reliable proxies.
