The area around the topmost two lumbar vertebrae looks normal.
I am learning about this in my Science class, and when a geologist looks at an extrusion, they know it's an extrusion because it is Igneous rock, and an extrusion helps tell the reletive ages of the layers around it.
The Lepore Extrusion was created on 2006-10-17.
The Mary-Sue Extrusion was created in 1999.

That is the correct spelling of "extrusion" (forming by pressing through a die or opening).
plasticity in the important mechanical property for the extrusion purpose.
(Intrusion) You can learn how old the rock layers are around it. the rock layers around under and all around the intrusion are always older than the intrusion itself. (EXTRUSION) the layers of rock bellow the extrusion is older than the extrusion.
Extrusion is a manufacturing process where material is pushed through a die to create a specific shape or profile.
Wikipedia has an whole article on the topic thermoplastic extrusion. Thermoplastic extrusion is a high volume manufacturing process in which raw plastic material is melted and formed into a continuous profile.

Geologists look at the texture of the rock, presence of gas bubbles, and the way the rock interacts with surrounding layers to determine how extrusions are formed. The angle of the volcano where the rock is found and the composition of the rock itself can also provide clues to its origin. Additionally, the presence of lava flows and other volcanic features in the surrounding area can help geologists understand the context in which the extrusion was formed.
