🛸👽 Today’s #macromonday shot was taken at the Munich Gem Shows, where I took a closer look at this kickass Seymchan Nickel-Iron Meteorite sphere!

The macro shows a unique structure that can only form in meteoritic metal: Widmanstätten patterns, aka Thomson figures. This structure forms due to 2 alloys within the nickel-iron material, kamacite and taenite—as the meteor (often an asteroid fragment) is flying through space, it cools slowly, and the 2 alloys differentiate and form distinct crystals.

When the meteor impacts with earth (becoming a meteorite), it is cut and treated with acid. The acid etches the meteorite and reveals its interior lattice structure, and these fine patterns of crystallization we call Widmanstätten patterns. A super cool formation that teaches us more about meteorites and the universe around us!

Mayan eccentric flints, 500 - 800 A.D. 

Eccentric flints, such as these, were sacred, high status offerings and evidence of the skill and technology of the Mayan workshops. A tapered base at the bottom may have been attached to a staff or scepter.

New to Tumblr, going to start dumping some of the stone carving that I've done here.

This big slate carving is based on a design from the Book of Kells, all hand carved with hammer and chisels.

Happy Fossil Friday! Let’s fly back in time to the Cretaceous some 110 million years ago to meet Tupuxuara leonardii. This flying reptile had a wingspan of about 15 ft (4.5 m) and a huge fan-shaped crest. But why the elaborate headgear? Scientists think that pterosaurs could have used their distinctive crests to steer during flight, to recognize members of the same species, or to attract mates. Like the crests of some modern birds, they may have also been brightly colored.

Natural Grape agate.

Grape agate is a botryoidal variety of chalcedony, distinguished by its clusters of tiny grape-like spheres.
