When #FossilFriday is also Black Friday, one looks for black fossils ... bonus points if they were apparently purchased from a science supplier like Wards. This on is a large specimen of Maclurites, an Ordovician taxon generally believed to be sedentary, suspension feeding gastropods.

Oreodonts are extinct mammals that looked similar to pigs and sheep, but were more closely related to camels. They are the most commonly found fossil in the White River Badlands in South Dakota, and this exceptional specimen from our collection shows an oreodont curled up inside its burrow.

Holy fucking shit this is a *real* image from a *real* (presumably peer-reviewed) paper in [Nature] Scientific Reports.

How many people had to sign off on this figure?

The editor, one hopes, the reviewer(s)? The copy editor?

What had to happen for THIS to get published?
Hey @nature.com, have you got an explanation for how the hell THIS happened? & especially why you accepted a paper with such a bizarre piece of genAI slop in it?!
& more to the point, why we should take you seriously at all going forward?

Native to the Americas, the Portuguese brought a “turkey” to India; in Ottoman Turkish, they were called “chicken from the land of India.”

An Englishman later described them as fowl from “Turkey,” and that’s where the English name appears to come from…

Waves coming off the basalt columns at Reynisfjara black sand beach. It's amazing that the camera technology is so good now that this was handheld at 1/8th second - the columns are sharp but I was able to capture the movement of the water too.

Started a new book. I've been fascinated with geology since the intro class I took my freshman year at Smith. This book puts me right back there again, curious to learn more with each page. It's SO good!

A geology book I recommend frequently is Timefulness by
Marcia Bjornerud. Nonfiction, looks at our relationship to time and how we understand it in geological terms. The author advocates for improving our understanding of geologic time as part of confronting our role in climate change.

While hunting for fossils, the unexpected is sometimes discovered. These finds can range from pottery shards to this fulgurite, or "fossil lightning," formed when lightning strikes the ground.
