- In my 'Environmental Geology' class today, we'll finish our coverage of glaciers, starting with erosional features (arêtes! spurs! horns! cirques! cols! roche moutonées!) & depositional features (till! moraines! drumlins! eskers!), lakes (tarns! finger! kettle!), then effects of climate change. 🧪🪨🧊🗻
- I can't believe I'm saying this, but GRIZZLED comes out in <30 days! I keep waiting for an asteroid to strike! It's felt like it would never happen for so long, I don't know what to do now that I'm here! It's going to be exclamation points from here on out, friends!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!🧪
- 🐻GRIZZLED🐻: Love Letters to 50 of North America's Least Understood Animals Def the biggest & most personal project of my career. Featuring artwork & foreword by Joel Sartore, as well as insights from a bajillion amazing scientists. 🧪 ❤️🔥I HOPE YOU LOVE IT❤️🔥 www.penguinrandomhouse.com/books/804002...
- Big congrats on the imminent (just 1-lunar-cycle) release of your new book, Jason! Best wishes for its success & delighting readers with your animal-inspired tales. 📚
- The near demise of Guinea worm disease in 2025 (only 10 cases worldwide) just a little more than a year after Jimmy Carter's passing seems like justice. He often said he planned to outlive this disease, & for all practical purposes, he did it. Thank you for all you did for others, Mr. President.
- Turning 34 today! If you'd like to help me celebrate, I'd be thrilled if you'd leave a compliment, a memory, or tell me about any work of mine (journalistic or fictional) that you've really liked or that meant something to you ❤️
- Happy Birthday, Asher! I think my favorite memory of you is when you came to one of my talks at Fernbank Museum in Atlanta GA & we had a nice chat afterwards. I'm recalling you were still in high school then, but please correct that if I'm misremembering. Very happy for your writing success since!

View full threadOh and by the way, got Dinosaurs Without Bones mentioned with your TLQ blurb. Sorry again for that oversight when it was first up.
- Wow Riley, thanks so much for adding 'Dinosaurs Without Bones' to my blurb for your next (eagerly anticipated) book! I'm likewise pleased to be blurbing between authors @annaleen.bsky.social & @stevebrusatte.bsky.social, whose books I also enjoy reading. 📚✍️
- The world is on fire so please enjoy these nice middle #jurassic trace #fossils. @ichnologist.bsky.social one for you! #geology #paleontology #dinosaur

- Oh, I thought those rocks & their trace fossils looked vaguely familiar! I was there & elsewhere along the Yorkshire coast on a 4-day field trip organized by U. of Manchester & others for the 1999 International Ichnofabric Workshop. I really need to go back someday. Thanks again for sharing!
- Thanks for the reminder to read Jericho Brown's stunning poetry. I'm incredibly lucky to share the same campus with him & often mention him & his works to students so they know about him, too.

- Double damn. I hate learning about the destruction of any fossils, but to lose trace fossils like these with evidence of extraordinary behaviors? Very disappointing.
- Thanks so much for posting this mix of very nice Jurassic invertebrate & vertebrate trace fossils! The burrows in the third photo I think are tops of U-shaped burrows, which I always enjoy seeing. Where are these from?
- in my 'Environmental Geology' class this a.m., we'll talk about glaciation and glaciers, including the effects of glaciations & glaciers of the pre-human past, & geological features of formerly glaciated landscapes. 🧪🪨⚒️🧊❄️🏔️

- I love that sense of geological memory in the landscape! Toward the start of today's class, I mentioned how we don't see any direct geological evidence of the Pleistocene glaciations here in Georgia, but that glacial cycles caused huge back-and-forth shifts in terrestrial ecosystems.
