In the summer of 1998, Russian scientists who were investigating an area 300 th km southwest of Moscow on the remains of a meteorite, discovered a piece of rock which enclosed an iron screw. Geologists estimate that the age of the rock is 300-320 million years. At that time there were not any intelligent life forms on earth, not even dinosaurs. The screw which is clearly visible in the head and nut, has a length of about cm and a diameter of about three millimeters.
“Historically speaking, animating female characters are really, really difficult, ’cause they have to go through these range of emotions, but they’re very, very — you have to keep them pretty and they’re very sensitive to — you can get them off a model very quickly.
