The Flügel-Course is a five-days course on carbonate microfacies which attracts participants from all over the world and takes place twice a year at @UniFAU in Erlangen, Germany. For more info check our website: https://t.co/mXpyXj7GCR
#PhotoOfTheMonth March 2024: #Thinsection of a bioclastic grainstone with gravitational dolomite cements, indicating very early dolomite precipitation in the vadose zone (stained with Alizarin-S, Upper Jurassic, N-Germany)
#Carbonate#Microfacies
This invasive species lives in waters with varying salinities and it suffers little competition from other serpulids (crossed polarized light, sample kindly provided by Hanno Kinkel) (2/2)
Note the nice geopetal structures underneath the big components. Fuerteventura, crossed polarized light, sample provided by Barbara Seuß @seuss_barbara (2/2)
#PhotoOfTheMonth September 2023: Partly silicified and bioeroded brachiopod shell embedded in a sediment rich in quartz grains and sponge spicules (“opoca”); uppermost Cretaceous, Poland
#Carbonate#Microfacies
#PhotoOfTheMonth August 2023: Partly dolomitized shell fragments, echinoderms, and glauconite in a Middle Triassic #limestone from the Upper Muschelkalk (Northern Bavaria, Germany). #Thinsection was stained with a mixed solution of alizarin red-S and potassium ferricyanide
#PhotoOfTheMonth July 2023: Poorly preserved Halimeda fragment (green alga) from the subsurface of the Bahamas; internal structure partly filled with sediment and/or cement crystals (thin section impregnated with blue resin).
#ThinSectionThursday
#PhotoOfTheMonth June 2023: Glendonite crystal ( = pseudomorph after the cryophilic carbonate mineral ikaite) from the Lower Jurassic (uppermost Pliensbachian) of S-Germany indicating a massive cooling in the European epicontinental sea (1/2)

My very first paper – hot off the press! 🎉Published open access in #Facies together with @Axel_Munnecke. If you are interested in glendonites and the Early Jurassic climate, download the .pdf here: https://t.co/2o8BpV9R1M

#PhotoOfTheMonth May 2023: The oldest Bonsai tree (Silurian, Gotland) 🌳 According to Andrej Ernst (Hamburg) it is an undescribed esthoniporate bryozoan
#thinsection
#PhotoOfTheMonth April 2023: Recent carbonate gravel (bivalves, gastropods, coralline red algae, serpulids, barnacles, sea urchins) from a rocky shore environment in N-Norway
And we're done once again! A huge thank you to the participants of the second #FlügelCourse for being such a vivid group! We would also like to thank the lecturers, the student helpers and all the people from @PaleoFAU and @UniFAU who made this year's Flügel courses possible! 🎉
