A ginger cat labelled "Me", pressing a grey cat's head labelled "Bluesky" into a red feeding bowl labelled "Minerals". Black, translucent crystals of smoky quartz rising out of a white feldspar groundmass sprinkled with tiny orange spessartine crystals, a type of garnet. Specimen from the Natural History Museum, London's collections.

Pollucite:
- A zeolite mineral
- An ore of caesium
- Forms in lithium rich granite pegmatites
- It's named after Pollux, a Greek mythological figure who was the brother of Castor (who gives his name to castorite/petalite, a commonly associated mineral) #minerals
A white, slightly translucent chunk of pollucite with a rough powdery looking texture. From Bernic Lake, Manitoba, Canada. Specimen on display in the Natural History Museum, London. A rough, flattened spherical crystal of pollucite, beige and translucent. From San Piero in Campo, Elba, Italy. Specimen on display in the Natural History Museum, London.

I hear and see your concerns. Over the weekend, a couple users hosted on Blacksky's PDS were banned from the Bluesky app and thus the Bluesky API servers. This was a weakness of our system I've been aware of and hoped we had more time to address before any kind of public incident. 1/11

Thin blue blades of kyanite sticking out of a beige quartz groundmass. From Itabira, Brazil. Specimen on display in the Natural History Museum, London. A lump consisting of blue and white kyanite prisms. Frm Botriphnie, Aberdeenshire, Scotland, UK. Specimen on display in the Natural History Museum, London. A cluster of white, opaque kyanite prisms. From Val di Vizze, Italy. Specimen on display in the Natural History Museum, London. An aggregate of kyanite blades, ranging from dark inky blue in the centre to paler blue towards the edges.

No, unfortunately not. But these are all photos of specimens in the Natural History Museum in London, so I'd definitely recommend a visit if you're ever in the area!

"I Contain Multitudes"

This digitally painted piece honors coyote by tracing its lineage from the first cells of life to the animal trotting our cities and the wilderness today.

The thread gives descriptions of all the extinct organisms shown in this piece (not to scale)
This digitally painted piece honors the survivor spirit of the coyote by tracing its lineage from the first cells of life to the animal trotting our landscapes today. Below the horizon, carefully chosen ancestors mark pivotal moments in adaptation, each contributing to the form and survivor we see today. Above the horizon, Coyote stands alert at the center, framed by both Denver’s skyline and a mountain backdrop, symbols of their ability to thrive in cities as well as wilderness. Embedded in the ground are the skulls and bones of carnivores whose lineages ended long ago, emphasizing Coyote’s persistence in contrast.
