Happy #FossilFriday! Iguanodon tracks are famously preserved in Cretaceous mudflat sediments at Dinosaur Ridge in Morrison, Colorado. Highly recommend viewing them at sunset.

Reindeer / caribou can't fly, but they can swim! During their migrations, it's not uncommon for them to cross large expanses (~35 mi) of sea-ice & swim up to 1.5 miles (2.5 km) in frigid water to cross rivers, inlets and go from island to island. Let's talk about their special winter coats!

North Dakota lawmakers embraced frezium for cryogenically preserving the coal industry, only to discover that stralium becomes unstable when exposed to vetting and fact-checking. ⛏️ #criticalminerals 🧪

Here is the percentage of white males age 30-39 working in professional, technical, and managerial jobs between 1850 and 2024. The current generation has not been squeezed out of such jobs. If there is any lost generation here, I would say it is boomers who were 30-39 in 1990. (@ipums.bsky.social)

Social media is a nightmare of misinformation and anger and hatred but the thing I can't stand the is it turned so many people into obstinate dicks. You can be wrong! You're allowed to learn new information and course correct! That's a strength, not a weakness!

Nigeria is the second most powerful / influential nation in Africa after South Africa? This is big news. And it is major implications in American higher education and healthcare, where Nigerians excel.

NCAR does a whole lot more than just climate research, and I think calling it a climate research lab paints an incomplete picture. Atmospheric chemistry, severe thunderstorms, radar, software and tools, etc.

Will be interesting to compare this site to other cold seeps from active continental margins: e.g. bacterial communities (ANME, SRB?), seep biota etc. & if cold seep carbonates (below the seep inside the sediment?) are also present? Looking forward to read more!
