A military piece like a plate carrier vest — which would hold body armor plates — requires a little more work.

Weighing less than half a pound each, they contain an explosive warhead that will fire a jet of molten metal downward capable of penetrating two and a half inches of armor plate.

Because the bulk of Dunkleosteus’s body was most likely composed of fragile cartilage, only the thick armor plates that encased its head and neck were preserved as fossils.

Others have adapted by relocating to places like Lviv, or changing their output to fill new wartime demands, like the lingerie seamstresses who have switched to sewing cloth vests to fit body armor plates.

They discovered several broken and healed armor plates concentrated around the creature’s hips that lacked any clear signs of disease or predation.
