I love my new camera.

I see you!

I have a new camera for field photography and I am not afraid to use it!

Close-up photographs of a naturally green harvestman (Algidia viridata ssp. bicolor) with a bumpy, textured body that resembles moss or algae. The arachnid's long spiny legs and bumpy body are shown from multiple angles against a blurred green background.

Never miss a chance to get face-to-face with a harvestman.

This is the stunning subspecies Algidia viridata ssp. bicolor, endemic to New Zealand!

They look like experimentally deformed samples, but they actually are natural samples!

A family of splitgill mushrooms grow from the bottom of an upturned turn like a cluster of fireworks exploding above the young spring growth of the forest floor. All photos by me

Here are some nice mushrooms

calcite grain in thin section

Ultra-thin sections of marbles are another story!

Strongly deformed calcite grain with deformation twins and recrystallized new grains forming all around.

"Dear Prof. Lupi,

We are delighted to accept your manuscript titled "High-enthalpy Larderello geothermal system, Italy, powered by thousands of cubic kilometres of mid-crustal magma" for publication in Communications Earth & Environment. Thank you!"

Glad to have coauthored this!

I am sure mineralogists know some crystal habit that fits to your pizza!

Happy International Day of Women and Girls in Science!

My journey has brought me so much. Fossil prep, museums, field work, travel, my first research publication, museum collections, connections, and of course, some of the best friendships I've ever had.

Keep that dream going!

I agree. Me and Ale studied at the same university and we went collecting rocks many times. He really is oassionate about petrology!

I will try asking the biologists 😂

At some point in life I became a geologist, but I sometimes ask myself 'how would it be like to have chosen a different major?'

Gladly, I have recently had the opportunity to try the 'naturalist' life! Here is a preprint of my spider paper that's under review 😍

This song is helping me coping with the stress of having to change country again

It's my fault. I mispelled it. It's the Tellaro Fault and the sheared rocks belong to the Tuscan Nappe!

Outcrop of deformed limestones

Sigmoidal structures (S-C structures) developed in deformed limestones within the Tellare fault. What's remarkable is the presence of white tensional veins (white) oblique to shear planes and parallel to the [theoretical] sigma 1.

See first comment for a sense of scale.

At the Marcello Carapezza volcanology center?

Welcome back to #fossilfriday!

Here are the impressions of the Inoceramid clam Mytiloides mytiloides. This specimen comes from the Late Cretaceous (Cenomanian-Turonian) Greenhorn Formation (Colorado Group) in northwestern Nebraska.
