Conventional wisdom for using corals as a paleo sea level indicator says that corals must live below the low tide level. This tidal pool, which has a sill above low tide, seems to break this rule!

I am a climate scientist, focused on paleoclimate, sea level change and the evolution of Quaternary glaciations. I reconstruct ice sheets using glacial isostatic adjustment and ice sheet modelling. In Japan but have been all over the place. 🇨🇦🇯🇵🇦🇺🇩🇪🇸🇪
It is probably going to be a while before I can make it back to Kumamoto after the earthquake earlier this week, but my wife sent me some pictures of our apartment. There is a big crack on the wall, but inside the only important thing that broke was the ANU mug I got when I handed in my PHD thesis.

Hello friends. I'm starting a new job today reporting for @nature.com on all things climate and Earth science, energy, and beyond.🌍Please get in touch if you're a researcher/gov staffer/startup with results/projects that deserve attention--or are facing problems we should know about. Contact in bio.
Fun bit: "we" didn't make this! Our older close "cousins" did.
This is the Clacton Spear. At 420,000 years old, it is the oldest known worked wooden weapon. It was found in 1911 in Clacton by amateur pre-historian Samuel Warren. It is approx 40cm long, 4cm wide & so is only the spear tip. Similar wooden spears (300,000 years old) have been found in Germany.

This poor guy had a meteorite crash through his house (luckily not hurt!), and it turned out to be a very rare type of meteorite. I wondered why the person was not thanked in the acknowledgements before I realized he was a coauthor on the paper. www.science.org/doi/10.1126/...

Any paleontologists out there that has advice on how one identifies the species of a fossil? I am looking at everything from microfossils (foraminifera), molluscs and corals. Is there a manual that teaches how to do this effectively? I am but a mere modeller!
Romero et al present an ice-free and paleo sea level chronology for James Ross Island in the northeastern Antarctic Peninsula area. They found that the advance of the local ice cap happened sometime after 40,000 years ago, and this implies a period of retreated ice in MIS 3. doi.org/10.1016/j.qu...

Anyone have experience extracting microfossils out of limestone? I read that using acetic acid on crushed limestone is the way to go. I have never done this before, but am looking to learn! The limestone I am looking at is not super lithified (it is Late Pleistocene) and in theory is mostly forams.

I have to say, the increasing presence of Cloudflare bot blocking this year is making the usage of the Internet increasingly frustrating. I shouldn't need to email a website administrator to be able to access a website! There has to be a better way of stopping the bots than using Cloudflare.
Several months ago, over a period of ~22 hours, I wrote down some thoughts that have been banging around in my head for the past few years. @geomorphica.bsky.social have just published those thoughts. #GeospatialRevolution 🧪⚒️❄️ journals.psu.edu/geomorphica/...

I am finding out that there are a lot of old journals in France (for instance, published before 1990) where there is hardly any record of them online, let alone scans. Where are you, "Revue de géomorphologie dynamique" and "Photo Interprétation"?
