The “oldest octopus” wasn’t an octopus after all

A 300-million-year-old fossil once believed to be the world’s oldest octopus has just been reclassified — and it changes what we thought we knew about evolution.

The species, Pohlsepia mazonensis, discovered in Illinois, was long considered the earliest known octopus.

But new research from the University of Reading tells a different story.

Using advanced synchrotron X-ray imaging, scientists found:

11 tooth-like structures in its radula
While true octopuses only have 7–9

That key difference revealed the truth…

It wasn’t an octopus.

It was a nautiloid.

Paleobiologist Thomas Clements put it simply:

“The most famous octopus fossil was never an octopus.”

This discovery reshapes the timeline:

Octopus origins move forward by ~150 million years
Nautiloid evidence moves back by ~220 million years

A reminder that even in science…

one discovery can rewrite history.

A U.S. Air Force F-35 stealth fighter crashed in Nevada on March 31 during a training mission, with the pilot ejecting safely, officials confirmed.

The jet, based at Nellis Air Force Base, went down roughly 25 miles northeast of Indian Springs within the Nevada Test and Training Range.

The pilot sustained minor injuries, and authorities emphasized the crash occurred in restricted airspace, posing no threat to civilians.

Emergency crews quickly secured the site, which remains under military control as an investigation into the cause is underway.

The F-35, an advanced and costly stealth aircraft operated by several nations, is once again under scrutiny following this training incident.

Hikaru Nakamura spent 67 minutes on one move at the 2026 Candidates—but still lost.

On move 13 vs Javokhir Sindarov, he chose the wrong move (h4 instead of Ne4), losing his advantage. Sindarov quickly countered and won.
