Didn t you say that the nautilus is extinct, why are there so many now?

The nautilus is not extinct.

The nautilus was almost all over the world during the Paleozoic era, but it is now almost extinct, and only six species of nautilus still exist in the deep sea of the South Pacific. There are not many species of nautilus, but there are as many as 2,500 fossil species. Nautilus fossils, also known as ammonites, were highly thriving populations during the Paleozoic era and constitute important stratigraphic indicators.

Geologists can use these fossils that exist in different sites and ages to study the related animal evolution, energy, minerals and environmental changes, and provide scientific data for the use and transformation of nature.

It's not extinct, it's just a small number.

What you see, no, I can't say.

However, it may be that another species of snail of the same genus may be used to pass it off.

A small number of surviving descendants of the nautilus, inhabiting the Indian Ocean.
