Giant Orthocone

The giant orthocone was a nautilus that looked like a squid in a cone. They existed 470 million years ago during the Ordivician Period. They were the top predator of there times. They lived in deep waters. They used their tentacles to crush up their prey. Their tentacle length measured up to 6 feet long. It ate everything that it could counting sea scorpions.

Giant Orthocones were very slow and very slow to turn so their prey had to stay on it's shell side for their survival.

Giant Orthocones are probably the biggest nautilus ever!!!
