Fossils?

[DenileRE]

These are fossils found on the sedimentary rock canyons outside Riyadh, Saudi Arabia. Can anyone confirm if these are fossils please?

Welcome to Tnet.

Neat finds. For sure they're fossils. Google >goniatite fossls<... that's what I think they are and probably around 250-350 million years old. They were marine cephalopods with a similar form to ammonites
