[News] Did trilobites hide from nautiloids?

[Phil]

Here's details of an interesting find from Ordovician Sweden, trilobites contained within fossilised tunnels they had dug. Were they hiding from nautiloid predators or is there another explanation?

Food for thought.

My thought is "yes they did".

(Isn't science great?)

I wonder what else shared the trilobites burrows...

(and yes, science is great!)

Nautiloid thoughts:

• Trilobite dinner
• How do I get into that tunnel
• Why dont trilobites just stay on the surface

Trilobite thoughts:

• Ha ha, cant get me now
• Where is that big worm that really lives in here?

Think giant bristleworms (rekindling nightmares), think Permian extinction...

How about: "Did trilobites hide from nautiloids inside of nautiloids?"

Here are photos of a Devonian fossil I found last summer - a trilobite inside an orthocone nautiloid. Apparently the association is known; it's thought that the trilobites hid inside to molt.
Internal mold of Michelinoceras? with trilobite Eldredgeops (Phacops). The length of the nautiloid fossil is 190mm.

Cool fossil, thanks for sharing it with us. Do you have any more fossils to share?

I have a coral book that contains a photograph of a giant bristleworm species removed from a persons reef tank. It was 5 feet long... looked like a giant centipede. I can see one of those making dinner out of a trilobite. Shoot... I can see one of those making dinner out of a nautilus. Nightmare material for sure. I wouldn't be hiding in it's hole!
