After posting the trilobite and the trackways, Gemini suggested this reconstruction of what those Ordovician traces might have looked like when they were made — trilobites walking across the sea floor ~450 million years ago.
I found this funny enough to share it.

An ichnofossil: Ordovician trilobite trackways, preserved as locomotion traces on the ancient sea floor.
Unlike body fossils, these are trace fossils recording behavior rather than anatomy.

An exceptionally well-preserved Ordovician trilobite I came across this week.
Not my find this time — but the level of detail is incredible, with the thoracic segments and cephalon almost perfectly intact.

I have been playing to visit Pompey for over 30 years. I hope I make in 2026!

Maybe he got confused with something they saw somewhere else.

Orthoconic cephalopod fossils (likely nautiloids, Orthocerida) preserved in a marine limestone slab.
These Paleozoic cephalopods (~400 Ma) are early relatives of modern squid and octopus, belonging to the same class (Cephalopoda), before the evolution of reduced or internal shells.
