Is there generality in decomposition across substrates? We tested this in an experiment across elevation, studying carrion, dung, leaves & wood. We found idiosynchratic patterns of decomp, with local conditions being more important than macroclimate @sebseibold.bsky.social doi.org/10.1002/ecm....

Welcome to the CAMBRIAN FECAL REVOLUTION. We didn't name it the Cambrian fecal explosion for obvious reasons. I'm happy to share this paper on fecal matter and its role in Cambrian ecosystems. So if you want to read a really shitty paper (50 days free access): authors.elsevier.com/a/1nYg8cZ3X7...

$50.1 million could fund over 400 doctorates; 933 years worth of annual curator salaries (UK), or running cost for a millennium-worth of free events like the Lyme Regis Fossil Festival. It is inane that people can accumulate such wealth, and use it explicitly to cause public harm.

Alan Grant in Jurassic Park was essential for me because it modeled what an ethical, kind, and caring male collaborator and research partner should be for all women in science. I won't put up with anything less.

Genuine rewrite the textbooks discovery! 🧪🦑 The same team led last year's discovery of even deeper chemosynthetic animal communities. And they are in a crewed submersible, so they actually SAW THE WHALE GRAVEYARD!!! Can't wait for them to keep exploring!

Made this graph of the high temperature in Chicago over the last 50 days. Mean is 57.3 and the s.d. was 15.4. Not sure how this compares to the usual this time of year, but it the swings feel more extreme than usual.

NSF GRFP awards just announced: www.research.gov/grfp/Awardee.... Nice to see that the overall numbers are back up, but only one award in paleontology (7 honorable mentions). No awards, one honorable mention for sedimentary geology.
