Resumen:
Here, we report for the first
time the presence of fungi and fungus-like microorganisms from a Mesozoic
hot-spring ecosystem. This Jurassic hot spring deposit (Patagonia, Argentina)
represents only the second known Phanerozoic hot spring ecosystem with an
associated microflora and contains diverse, exceptionally-preserved
microorganisms. Preserved remains include variously-shaped bodies, spores and
hyphae that show affinities with ascomycetes, chytridiomycetes, oomycetes and
others of uncertain affinity. Many of these microorganisms occur dispersed in
chert matrix, but others are associated with variously decayed organic remains
including animals and plants, mainly horsetails. This report expands the fungal
fossil record and provides a unique opportunity to learn about the biology of
Mesozoic microorganisms.
