A rise in Alphaproteobacteria seemingly occurred alongside the rise of eukaryotes. See our new paper to find out why! 🦠 Genetics re-establish the utility of 2-methylhopanes as cyanobacterial biomarkers before 750 million years ago nature.com/articles/s4155…

@kippmichael I admit it was a pretty niche joke, but you are one of the privileged few who actually get it 🧢😎😆

@Bishop_geo Great caps 🧢

"We love our caps". Exploring the rise of algae transition in the central flinders ranges with Prof. Jochen Brocks. Ft. the Elatina Fm. glacials - Nuccaleena Cap Dolostone, marking the end of the Snowball Earth. Also Ft. some gorgeous giant wave ripples in the cap dolostone.

#COLDANDSTORMY to #HOTANDWARMY

Fantastic work from Brocks et al. published in Nature yesterday. Discovering a lost world of complex life. It has been awesome seeing this work come to fruition. doi.org/10.1038/d41586… The paper can be found here. nature.com/articles/s4158…

One of my greatest pleasures is to teach about the wonders of rocks!! About how the seemingly ordinary is totally extraordinary!! 🪨 Ft. Lachlan Fold Belt seds 🤘

Interesting results from the Brocks lab, ANU, found the animals ate bacteria and algae that was sourced from the ocean floor. Findings are published in Current Biology cell.com/current-biolog…

World's earliest animals in Ediacara ate algae and even had sophisticated guts, study suggests abc.net.au/news/science/2…

Which came first? The #oxygen or the #eukaryotes? @Bishop_geo gives us some clues at #VGESSS2022 @GeoSocAustralia

@JarrettGeo sooo cool!

Three days until my manuscript is due, procrastination on the Wombo app with an AI artwork of my PhD thesis: Biogeochemical evolution in the Neoproterozoic Amadeus Basin, central Australia.

Brilliant talk from @Bishop_geo at ANU on geological evidence for the Snowball Earth episode. #virtualgesss @GeoSocAustralia

@tectonicSZ @GeoSocAustralia Thanks for having me @tectonicSZ @GeoSocAustralia. Great fun being with you all #virtualgesss

@geoAlanC @sediAus sooo cool!!

Exciting stuff coming from down the hall this week. Fantastic work Clinton Foster!

Part 2 of my 2 part series on the early evolution of complex life. See what cataclysms drove life to all new heights. From Soup the Slime - Evolution and Revolution 🦠🧪

My first contribution to @On_Circulation. Take a step back in time to Earth's ancient microbial beginnings, the story of complex life 🔬🧫. Part 1 - Reminiscences of a soupy beginning

@PeterHainesGeo @sedsnstroms What a patch job 😆😂

@sedsnstroms The usual assumption, which I also made on first visiting the Ediacaran GSSP, is that the pmag holes were drilled around the already placed spike. But these photos from Raub et al 2007 show they pre-date it, and the spike covers two more holes.

Good morning to everyone who can study an outcrop without ruining it. 😔

@maxlechte Biomarkers and microfossils - what a beautiful marriage 😂👌

@Bishop_geo Just re-read my tweet - should have been “relies heavily” upon... 😂 (limited characters!) Biomarkers of course doing heavy lifting as well 💪

The study of early eukaryotes relies on microfossils preserved in shale — @WoltzTina @SusaPorter @palaeoheda @chrisjunium @NeoprotFossil & team test (& support) the idea that higher organic carbon levels actually leads to poor fossil preservation 🦠⛰️ doi.org/10.1130/G48116…
