The tarantulas are afoot! This little fellow was on my front porch when I got home...by coincidence, wandering across Permian-aged fossil footprints from the Coconino Sandstone.

Happy #FossilFriday! Here's the first ankylosaur osteoderm from our field area in the "Mesaverde" Formation, Bighorn Basin, Wyoming. We have a few teeth, but this is the first non-tooth fossil from these iconic dinosaurs. Collected under #BLMPaleo permit, accessioned at @alfpaleo.bsky.social 🧪

The latest batch of spicy brown mustard is in the jar and ready to sit for a day or two while it mellows. It's going to go great with some brats on the grill later this week!

Happy #HomeFermentationDay! To celebrate the fun of fermentation beyond just beer, I started a lacto-ferment for some heirloom beets from the garden. They are all covered in brine and waiting for some microbial magic to turn them into pickled beets.

On Monday, I gave a presentation about paleontology, sponsored by the public library at my hometown in rural South Dakota (population 698). It was a blast, and I am glad to have had the privilege to speak about my journey. <thread>

Back where my love of museums started! Who would have thought it would end up as a career? The Douglas County (South Dakota) museum complex is a small-town gem, complete with two-headed calf and a bunch of local memorabilia from the history of the area.

I'm proud of this label that I designed for one of my recent homebrews! Making beer is such an enjoyable and creative hobby, and it's fun to flex my brain in ways that the rest of life doesn't. Details on the beer itself at my blog: andybrews.com/2026/05/26/a...

At the very bottom, text says, "Farke Brewing, Claremont, California"

One of the biggest joys of museum collections is the fact that the fossils are preserved for the future. During a recent collection visit to the SDSMT Museum of Geology, I ran across some boxes of specimens that I helped ID and curate nearly a quarter of a century ago! 🦖🦕🧪

I just got really, really, really excited by this fossil! Museum preparator Andrew has been working on this bit of skull from the "Mesaverde" Fm. of Wyoming (BLM permit, accessioned @alfpaleo.bsky.social). Turns out to be most of the back part of a croc skull - a VERY important specimen! 🧪🐊

Excellent thread (speaking also as now ?mature stage of former teenage dino nerd)! I'll also, somewhat grumpily, say that many of us professionals also fan the flames of dino fandom, engage in meme-ing and fanbase engagement, and then are suddenly surprised when a fandom behaves like a fandom.

The specimen is a great example of how taking a little extra time to collect a fossil can pay off. Part of the bone was in situ on the underside of a low sandstone ledge - a piece or two was directly below it, but others had washed a good distance away.

When I was 10, I wrote to Mark with my ideas about dinosaur digestion. His response was encouraging, gracious, and part of what kept my interest in paleontology alive, and likely led in part to my path into education with high schoolers. Thank you, Mark. 2/2
Letter with "American Museum of Natural History" in header.
3 December, 1991
addressed to Mr. Andy Farke, Armour, South Dakota 57313
Text of letter:
Dear Andy:
Thank you for the letter and drawing regarding your theory on gizzards in Coelophysis. Indeed, small rounded stones called gastroliths have been found within rib cages of prehistoric dinosaurs and their relatives. Furthermore, modern day crocodiles and chickens, close relatives of dinosaurs, ingest small stones. Based on this evidence, it is likely that the digestive system of Ceolophysis included a gizzard.

Though you are far away from the American Museum, I encourage you to keep up your interest in paleontology and science. There are many good books in the library that can help you learn about fossils and how scientists develop theories from them. Furthermore, many dinosaur remains have been found in your home state of South Dakota. They include Tyrannosaurus rex, Triceratops and Anatosaurus.

We hope you will get a chance to visit our museum in the future.

Sincerely,

Mark A. Norell
Assistant Curator of Vertebrate Paleontology

Incredibly cool to get up-close views of this epaulette shark at the Denver Zoo recently. We find a ton of orectolobiform teeth in our sites in the "Mesaverde" Formation of Wyoming, so it's quite helpful and interesting for me to see a modern example in the flesh!
