I have made a new UQuiz:

What your opinions on dinosaurs say about you.

Have fun (it's a long one)

#in my mineralogy class we had a slideshow presentation about which rocks were dangerous to put in your mouth #there were test questions based on this

hey

what do you think about geology

rocks taste good

Geological horror. You find a geode and crack it open and the crystal lining its walls is human blood that can't be genetically matched to anyone. You find a human skeleton but every one of the bones is made from rock, a rock that you know can't be whittled into those shapes. You find layers of clay and loam that sport ancient fossils at the top and the still-rotting corpses of modern animals at the bottom.

Daily affirmations for Paleontologists and people of similar professions: You CAN create a video tapping rocks/artifacts whispering "paleontology/(your field of study here)" I believe in you
